The Monastic Pint Answers from church history on today's questions

Is premarital sex a sin?

What Christian writers said, from about AD 70 to 1930.

246 passages · 54 writers · 14 centuries

The short answer

The writers in this collection do not use the term premarital sex. They write about fornication, which Philaret of Moscow (1839) defines as irregular carnal love between unmarried persons and which Basil (AD 357) says is not wedlock. Of the 246 passages here, 150 state a position on it and 96 mention it in passing, as in lists of sins or in comments on other texts. The writers who state a position treat intercourse outside marriage as forbidden, ground the ban in Scripture, the commandments, and natural law, and call it a grave sin that wrongs the body that belongs to Christ. They tell those who cannot remain continent to marry, and they rank virginity above marriage and marriage above fornication. They differ on discipline, and the passages on penance and restoration disagree on whether pardon is open to those who have committed it.

Forbidden by divine and natural law

34 passages · 13 writers · 300s to 1900s

Writers ground the ban on intercourse outside marriage in Scripture, the commandments, natural law, and the order of marriage.

c. 303–313

Let lust not go beyond the marriage-bed, but be subservient to the procreation of children. For a too great eagerness for pleasure both produces danger and generates disgrace, and that which is especially to be avoided, leads to eternal death.

Lactantius, The Divine Institutes 8.58

c. 370–419

Earthly laws give a free rein to the unchastity of men, merely condemning seduction and adultery; lust is allowed to range unrestrained among brothels and slave girls, as if the guilt were constituted by the rank of the person assailed and not by the purpose of the assailant. But with us Christians what is unlawful for women is equally unlawful for men, and as both serve the same God both are bound by the same obligations.

Jerome, The Letters of St. Jerome 77

1265–1274

Now this obligation which binds the female and her mate to remain together constitutes matrimony. Consequently it is evident that it is contrary to the natural law for a man to have intercourse with a woman who is not married to him, which is the signification of a concubine.

Thomas Aquinas, Summa Theologica Suppl..Q65.A3

1563

Q. What is God’s will for us in the seventh commandment? A. That God condemns all unchastity, 1 and that we should therefore detest it wholeheartedly 2 and live decent and chaste lives, 3 within or outside of the holy state of marriage.

Reformed Churches, Heidelberg Catechism 107

1755–1765

But the case is quite otherwise with fornication. This is not indifferent, but at all times evil. For the body is for the Lord - Designed only for his service.

John Wesley, Notes on the Bible 7.6

How grave the sin is

35 passages · 15 writers · 100s to 1700s

Writers describe fornication as a grave or mortal sin, set it among sins that bar entry to the kingdom, and rank it against other sins.

c. 110–140

If we please Him in this present world, we shall receive also the future world, according as He has promised to us that He will raise us again from the dead, and that if we live worthily of Him, “we shall also reign together with Him,” provided only we believe. In like manner, let the young men also be blameless in all things, being especially careful to preserve purity, and keeping themselves in, as with a bridle, from every kind of evil. For it is well that they should be cut off from the lusts that are in the world, since “every lust warreth against the spirit;” and “neither fornicators, nor effeminate, nor abusers of themselves with mankind, shall inherit the kingdom of God,” nor those who do things inconsistent and unbecoming.

Polycarp of Smyrna, Epistle to the Philippians 5

c. 246–258

That the sin of fornication is grievous. In the first Epistle of Paul to the Corinthians: “Every sin whatsoever a man doeth is outside the body; but he who committeth fornication sinneth against his own body. Ye are not your own, for ye are bought with a great price.

Cyprian of Carthage, The Treatises of Cyprian 12.4.65

c. 389–392

A dreadful, a dreadful thing is fornication, and an agent for everlasting punishment; and even in this world it brings with it ten thousand woes.

John Chrysostom, The Homilies of St. John Chrysostom on the Gospel of St. John 65

1265–1274

I answer that, As we have already stated (Sent. ii, D, 42, Q[1], A[4]), those sins are mortal in their genus which violate the bond of friendship between man and God, and between man and man; for such sins are against the two precepts of charity which is the life of the soul. Wherefore since the intercourse of fornication destroys the due relations of the parent with the offspring that is nature's aim in sexual intercourse, there can be no doubt that simple fornication by its very nature is a mortal sin even though there were no written law.

Thomas Aquinas, Summa Theologica Suppl..Q65.A4

1725

Note, The sin of fornication is a great injury in a Christian to his head and lord, and a great reproach and blot on his profession. It is no wonder therefore that the apostle should say, " Flee fornication ( v. 18 ), avoid it, keep out of the reach of temptations to it, of provoking objects.

Matthew Henry, Commentary on First Corinthians 6.3

The body, Christ, and the temple

27 passages · 14 writers · 100s to 1900s

Writers on 1 Corinthians 6 say fornication wrongs the body, which belongs to Christ and is a temple of the Spirit.

180

Here he manifestly declares the body to be the temple in which the Spirit dwells. … He speaks these things, not in reference to some other spiritual man; for a being of such a nature could have nothing to do with an harlot: but he declares “our body,” that is, the flesh which continues in sanctity and purity, to be “the members of Christ;” but that when it becomes one with an harlot, it becomes the members of an harlot.

Irenaeus of Lyons, Against Heresies: Book V 7

357–378

You have taken the members of Christ and made them the members of a harlot. This is an evil with which no other can be matched.

Basil of Caesarea, The Letters 46

1540–1564

Having set before us honorable conduct, he now shows how much we ought to abhor fornication , setting before us the enormity of its wickedness and baseness. Now he shows its greatness by comparison — that this sin alone, of all sins, puts a brand of disgrace upon the body.

John Calvin, Commentary on Corinthians, Vol. 1 6.3

1755–1765

Flee fornication - All unlawful commerce with women, with speed, with abhorrence, with all your might. Every sin that a man commits against his neighbour terminates upon an object out of himself, and does not so immediately pollute his body, though it does his soul. But he that committeth fornication, sinneth against his own body - Pollutes, dishonours, and degrades it to a level with brute beasts.

John Wesley, Notes on the Bible 7.6

1839

What motives does holy Scripture set before us to make us flee fornication and live chastely? It bids us keep our bodies in purity, because they are the members of Christ, and temples of the Holy Ghost; while, on the other hand, he who committeth fornication sinneth against his own body; that is, corrupts it, infects it with diseases, and, further, hurts his mental faculties, such as imagination and memory.

Philaret of Moscow, The Longer Catechism of the Orthodox, Catholic, Eastern Church q. 584–591

Marriage as the remedy

25 passages · 13 writers · 100s to 1800s

Writers say the unmarried who cannot remain continent are to marry, and that marriage is God's provision against fornication.

c. 290–300

Come, now, and let us examine more carefully the very words which are before us, and observe that the apostle did not grant these things unconditionally to all, but first laid down the reason on account of which he was led to this. For, having set forth that “it is good for a man not to touch a woman,” he added immediately, “Nevertheless, to avoid fornication, let every man have his own wife” —that is, “on account of the fornication which would arise from your being unable to restrain your voluptuousness”—“and let every woman have her own husband.

Methodius of Olympus, The Banquet of the Ten Virgins; or Concerning Chastity 4.12

c. 348–350

But if they have not continency, let them marry: for it is better to marry than to burn . But let all the other practices be banished afar, fornication, adultery, and every kind of licentiousness: and let the body be kept pure for the Lord, that the Lord also may have respect unto the body.

Cyril of Jerusalem, The Catechetical Lectures of S. Cyril 8

590–604

But fornicators and adulterers God will judge ( Heb. xiii. 4 ). They are therefore to be admonished that, if they suffer from the storms of temptation with risk to their safety, they should seek the port of wedlock. For it is written, It is better to marry than to burn ( 1 Cor. vii. 9 ). They come, in fact, to marriage without blame, if only they have not vowed better things.

Gregory the Great, The Book of Pastoral Rule, and Selected Epistles, of Gregory the Great 4.4.28

1559

The Lord prohibits fornication, therefore he requires purity and chastity. The only method which each has of preserving it is to measure himself by his capacity. Let no man rashly despise matrimony as a thing useless or superfluous to him; let no man long for celibacy unless he is able to dispense with the married state.

John Calvin, Institutes of the Christian Religion II.8

1725

It is convenient therefore that the unmarried abide as I, which plainly implies that Paul was at that time unmarried. But, if they cannot contain, let them marry; for it is better to marry than to burn. This is God's remedy for lust. … Marriage is honourable in all; but it is a duty in those who cannot contain nor conquer those inclinations.

Matthew Henry, Commentary on First Corinthians 7.1

What counts as fornication

9 passages · 8 writers · 100s to 1800s

Writers define simple fornication as intercourse between unmarried persons and discuss betrothal, seduction, and unions without a marriage compact.

c. 197–220

Every homicide, even outside a wood, is banditry. So, too, whoever enjoys any other than nuptial intercourse, in whatever place, and in the person of whatever woman, makes himself guilty of adultery and fornication. Accordingly, among us, secret connections as well—connections, that is, not first professed in presence of the Church—run risk of being judged akin to adultery and fornication; nor must we let them, if thereafter woven together by the covering of marriage, elude the charge.

Tertullian, On Modesty 4

357–378

Fornication is not wedlock, nor yet the beginning of wedlock. Wherefore it is best, if possible, to put asunder those who are united in fornication. If they are set on cohabitation, let them admit the penalty of fornication.

Basil of Caesarea, The Letters 199

401

For, if a man should take unto him any one for a time, until he find another worthy either of his honors or of his means, to marry as his compeer; in his soul itself he is an adulterer, and that not with her whom he is desirous of finding, but with her, with whom he so lies, as not to have with her the partnership of a husband. Whence she also herself, knowing and willing this, certainly acts unchastely in having intercourse with him, with whom she has not the compact of a wife.

Augustine of Hippo, On the Good of Marriage 5

1647

Adultery or fornication committed after a contract, being detected before marriage, giveth just occasion to the innocent party to dissolve that contract.

Westminster Assembly, Westminster Confession of Faith 24.5

1839

Fornication; or irregular carnal love between unmarried persons.

Philaret of Moscow, The Longer Catechism of the Orthodox, Catholic, Eastern Church q. 584–591

Desire and thoughts

8 passages · 5 writers · 100s to 1700s

Writers extend the ban from the act to desire, looks, and imaginations.

c. 150–200

Beware, therefore, of fornication; and if you wish to be pure in your mind, guard your senses against every woman. And command them likewise not to company with men, that they also be pure in their mind. For constant meetings, even though the ungodly deed be not wrought, are to them an irremediable disease, and to us an everlasting reproach of Beliar; for fornication hath neither understanding nor godliness in itself, and all jealousy dwelleth in the desire thereof.

The Testaments of the Twelve Patriarchs, The Testaments of the Twelve Patriarchs 3

1265–1274

Wherefore since fornication is a mortal sin, and much more so the other kinds of lust, it follows that in such like sins not only consent to the act but also consent to the pleasure is a mortal sin.

Thomas Aquinas, Summa Theologica II-II.Q154.A4

1647

Q. 139. What are the sins forbidden in the seventh commandment? A. The sins forbidden in the seventh commandment, besides the neglect of the duties required, are, adultery, fornication, rape, incest, sodomy, and all unnatural lusts; all unclean imaginations, thoughts, purposes, and affections; all corrupt or filthy communications, or listening thereunto; wanton looks, impudent or light behavior, immodest apparel; prohibiting of lawful, and dispensing with unlawful marriages; allowing, tolerating, keeping of stews, and resorting to them; entangling vows of single life, undue delay of marriage; having more wives or husbands than one at the same time; unjust divorce, or desertion; idleness, gluttony, drunkenness, unchaste company; lascivious songs, books, pictures, dancings, stage plays; and all other provocations to, or acts of uncleanness, either in ourselves or others.

Westminster Assembly, Westminster Larger Catechism 139

1650

I call all desires irregular and sinful that are not sanctified: 1. by the holy institution, or by being within the protection of marriage; 2. by being within the order of nature; 3. by being within the moderation of Christian modesty. Against the first are fornication, adultery, and all voluntary pollutions of either sex.

Jeremy Taylor, Holy Living 2.3.1

1714

Whosoever looketh on a woman (not only another man's wife, as some would have it, but any woman), to lust after her, has committed adultery with her in his heart, v. 28 . This command forbids not only the acts of fornication and adultery, but, (1.) All appetites to them, all lusting after the forbidden object; this is the beginning of the sin, lust conceiving ( James i. 15 ); it is a bad step towards the sin; and where the lust is dwelt upon and approved, and the wanton desire is rolled under the tongue as a sweet morsel, it is the commission of sin, as far as the heart can do it; there wants nothing but convenient opportunity for the sin itself.

Matthew Henry, Commentary on Matthew 5.6

Penance, discipline, and forgiveness

8 passages · 7 writers · 100s to 1500s

Writers and canons set penance, exclusion, and restoration for those who commit fornication, and disagree on whether pardon is open.

c. 190–202

She who has committed fornication liveth in sin, and is dead to the commandments; but she who has repented, being as it were born again by the change in her life, has a regeneration of life; the old harlot being dead, and she who has been regenerated by repentance having come back again to life.

Clement of Alexandria, The Stromata, or Miscellanies 2.23

c. 197–220

“Every unrighteousness is sin; and there is a sin unto death. But we know that every one who hath been born of God sinneth not” —to wit, the sin which is unto death. Thus there is no course left for you, but either to deny that adultery and fornication are mortal sins; or else to confess them irremissible, for which it is not permitted even to make successful intercession.

Tertullian, On Modesty 19

c. 348–350

But perhaps even among women some one will say, I have committed fornication, and adultery, I have defiled my body by excesses of all kinds: is there salvation for me? Turn thine eyes, O woman, upon Rahab, and look thou also for salvation; for if she who had been openly and publicly a harlot was saved by repentance, is not she who on some one occasion before receiving grace committed fornication to be saved by repentance and fasting?

Cyril of Jerusalem, The Catechetical Lectures of S. Cyril 6

357–378

In the case of a man having a wife by seduction, be it secret or by violence, he must be held guilty of fornication. The punishment of fornicators is fixed at four years.

Basil of Caesarea, The Letters 199

1540–1564

Some might think it harsh, or inconsistent with the Divine goodness, that all who have incurred the guilt of fornication or covetousness are excluded from the inheritance of the kingdom of heaven. But the answer is easy. Paul does not say that those who have fallen into those sins, and recovered from them, are not pardoned, but pronounces sentence on the sins themselves.

John Calvin, Commentary on Galatians and Ephesians Ephesians 5.2

Virginity compared with marriage

4 passages · 4 writers · 300s to 700s

Writers rank continence above marriage and marriage above fornication.

c. 370–419

Suppose I say, “It is better to be a virgin than a married woman;” in this case I have preferred to what is good what is still better. But suppose I go a step further and say, “It is better to marry than to commit fornication;” in that case I have preferred, not a better thing to a good thing, but a good thing to a bad one. There is a wide difference between the two cases; for, while virginity is related to marriage as better is to good, marriage is related to fornication as good is to bad.

Jerome, The Letters of St. Jerome 48

401

For intercourse of marriage for the sake of begetting hath not fault; but for the satisfying of lust, but yet with husband or wife, by reason of the faith of the bed, it hath venial fault: but adultery or fornication hath deadly fault, and, through this, continence from all intercourse is indeed better even than the intercourse of marriage itself, which takes place for the sake of begetting.

Augustine of Hippo, On the Good of Marriage 6

c. 403–406

Blessed is such beauty and worthy of God; for nothing is to be compared with virginity. Thus, then, those who set marriage side by side with fornication grievously err; and those who think that marriage is to be placed on an equal footing with virginity are utterly wretched and foolish. But this distinction must be maintained by wise people, that marriage belongs to those things which may be excused, while virginity points to glory, and fornication must incur punishment unless its guilt is purged away through atonement.’

Sulpitius Severus, Dialogues of Sulpitius Severus 2.10

c. 726–749

Good indeed is the procreation of children enjoined by the law, and good is marriage on account of fornications, for it does away with these , and by lawful intercourse does not permit the madness of desire to be enflamed into unlawful acts. Good is marriage for those who have no continence: but that virginity is better which increases the fruitfulness of the soul and offers to God the seasonable fruit of prayer.

John of Damascus, John of Damascus: Exposition of the Orthodox Faith 4.24

Passing mentions

Named among sins that bar entry to the kingdom

11 passages · 10 writers · 100s to 1900s

Writers cite 1 Corinthians 6:9-10 to place fornicators among those who do not inherit the kingdom of God.

180

Be not deceived: neither fornicators, nor idolaters, nor adulterers, not effeminate, nor abusers of themselves with mankind, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.” And as it was not to those who are without that he said these things, but to us, lest we should be cast forth from the kingdom of God, by doing any such thing, he proceeds to say, “And such indeed were ye; but ye are washed, but ye are sanctified in the name of the Lord Jesus Christ, and by the Spirit of our God.” And just as then, those who led vicious lives, and put other people astray, were condemned and cast out, so also even now the offending eye is plucked out, and the foot and the hand, lest the rest of the body perish in like manner. And we have the precept: “If any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner, with such an one go not to eat.”

Irenaeus of Lyons, Against Heresies: Book IV 28

400–401

Let us therefore not flatter the Catholic who is hemmed in with all these vices, nor venture, merely because he is a Catholic Christian, to promise him the impunity which holy Scripture does not prom ise him; nor, if he has any one of the faults above mentioned, ought we to promise him a partnership in that heavenly land. For, in writing to the Corinthians, the apostle enumerates the several sins, under each of which it is implicitly understood that it shall not inherit the kingdom of God: "Be not deceived," he says: "neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God." He does not say, those who possess all these vices together shall not inherit the kingdom of God; but neither these nor those: so that, as each is named, you may understand that no one of them shall inherit the kingdom of God.

Augustine of Hippo, On Baptism, Against the Donatists 6.19

1547

In opposition also to the subtle wits of certain men, who, by pleasing speeches and good words, seduce the hearts, of the innocent, it is to be maintained, that the received grace of Justification is lost, not only by infidelity whereby even faith itself is lost, but also by any other mortal sin whatever, though faith be not lost; thus defending the doctrine of the divine law, which excludes from the kingdom of God not only the unbelieving, but the faithful also [who are] fornicators, adulterers, effeminate, liers with mankind, thieves, covetous, drunkards, railers, extortioners, and all others who commit deadly sins; from which, with the help of divine grace, they can refrain, and on account of which they are separated from the grace of Christ.

Council of Trent, Canons and Dogmatic Decrees of the Council of Trent Session 6, ch. XV

1563

Q. Can those be saved who do not turn to God from their ungrateful and unrepentant ways? A. By no means. Scripture tells us that no unchaste person, no idolater, adulterer, thief, no covetous person, no drunkard, slanderer, robber, or the like will inherit the kingdom of God.

Reformed Churches, Heidelberg Catechism 87

1834–1885

The unholy cannot be saved, Co1 6:9-10. So God has determined; and this purpose cannot be evaded or escaped. It is fixed; and men may think of it as they please, still it is true that there are large classes of people who, if they continue such, cannot inherit the kingdom of God. The fornicator, the idolater, the drunkard, and the covetous, cannot enter heaven.

Albert Barnes, Notes on the Bible First Corinthians 6:20

Marriage as the remedy for fornication

9 passages · 9 writers · 200s to 1700s

Writers cite 1 Corinthians 7:2 and 7:9 and say marriage is permitted or commanded to prevent fornication.

c. 244–249

But in the new covenant also there are some legal injunctions of the same order as, “Moses for your hardness of heart suffered you to put away your wives;” for example, because of our hardness of heart, it has been written on account of our weakness, “But because of fornications, let each man have his own wife and let each woman have her own husband;” and this, “Let the husband render unto the wife her due, and likewise also the wife unto the husband.” To these sayings it is accordingly subjoined, “But this I say by way of permission, not of commandment.”

Origen of Alexandria, Origen's Commentary on the Gospel of Matthew 2.7.23

c. 300–400

“‘Since, therefore, the erotic desire occurs for the sake of continuation and legitimate increasing, as I have said, it behoves parents providing for the chastity of their children to anticipate the desire, by imbuing them with instruction by means of chaste books, and to accustom them beforehand by excellent discourses; for custom is a second nature. And in addition to this, frequently to remind them of the punishments appointed by the laws, that, using fear as a bridle, they may not run on in wicked pleasures. And it behoves them also, before the springing of the desire, to satisfy the natural passion of puberty by marriage, first persuading them not to look upon the beauty of another woman.

Pseudo-Clement, Pseudo-Clementine Literature 4.8.25

1530

First, concerning such as contract matrimony, they teach on our part that it is lawful for all men who are not fitted for single life to contract matrimony, because vows cannot annul the ordinance and commandment of God. But the commandment of God is 1 Corinthians 7:2 , To avoid fornication, let every man have his own wife.

Lutheran Church, Augsburg Confession 24.5

1755–1765

It is good for a man - Who is master of himself. … 2. Yet, when it is needful, in order to avoid fornication, let every man have his own wife. His own - For Christianity allows no polygamy.

John Wesley, Notes on the Bible 7.7

Discipline, restoration, and forgiveness

9 passages · 9 writers · 100s to 1800s

Writers and councils address exclusion from communion, penance, and whether fornicators may be restored.

c. 197–220

I admit that the sinner portrayed in each parable is one who is already a Christian; yet not that on this account must he be affirmed to be such an one as can be restored, through repentance, from the crime of adultery and fornication. For although he be said to “have perished,” there will be the kind of perdition to treat of; inasmuch as the “ewe” “perished” not by dying, but by straying; and the “drachma” not by being destroyed, but by being hidden.

Tertullian, On Modesty 7

c. 315

If a presbyter marry, let him be removed from his order; but if he commit fornication or adultery, let him be altogether cast out [i.e. of communion] and put to penance. … A presbyter who marries is removed from the exercise of the priesthood but retains his honour and seat. But he that commits fornication or adultery is cast forth altogether and put to penance.

c. 348–350

For all things whatsoever thou hast done shall be forgiven thee, whether it be fornication, or adultery, or any other such form of licentiousness. What can be a greater sin than to crucify Christ? Yet even of this Baptism can purify.

Cyril of Jerusalem, The Catechetical Lectures of S. Cyril 7

1070–1109

True it is that my conscience and sense of guilt deserves damnation, and that my penance is not enough for satisfaction; but yet it is certain that Thy mercy out strips all Thy resentment. Spare, therefore, Thou good Lord, to whom salvation belongeth, and who desirest not the death of the sinner, spare my sinful soul; for it flies, frightened by Thy frightening justice, to Thy consoling mercy; that so, since the treasure of his marred virginity is now—O grief!—irrecoverable, yet the punishment due to fornication may not be inevitable to the penitent; for ’tis neither impossible to Thy omnipotence, nor ill-becoming to Thy justice, nor unwonted to Thy mercy; since Thou art good, and since Thy mercy reaches to eternity, Thou who art blessed for ever more.

Anselm of Canterbury, Meditations and Prayers 2.3

1872

A second law of this visible kingdom of our Lord is that heretics and those guilty of scandalous offences should be excommunicated. “A man that is an heretic, after the first and second admonition reject.” (Titus iii. 10.) “I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.” (1 Cor. v. 11.) Our Lord teaches that such an offender when he refuses to hear “the Church” is to be regarded as a “heathen man and a publican.”

Charles Hodge, Systematic Theology III.11.3

The body as temple and members of Christ

8 passages · 8 writers · 100s to 1900s

Writers cite 1 Corinthians 6 to say fornication defiles the body that belongs to Christ.

c. 190–202

Those, therefore, who are consecrated to God must never live mortally ( θνητῶς ). “Nor,” as Paul says, “is it meet to make the members of Christ the members of an harlot; nor must the temple of God be made the temple of base affections.” Remember the four and twenty thousand that were rejected for fornication.

Clement of Alexandria, The Instructor 2.10

c. 246–249

And are not they who wallow in dissoluteness, as do the majority of mankind, and they who associate promiscuously with common harlots, and who teach that such practices are not wholly contrary to propriety, worms who roll in mire?—especially when they are compared with those who have been taught not to take the “members of Christ,” and the body inhabited by the Word, and make them the “members of a harlot;” and who have already learned that the body of the rational being, as consecrated to the God of all things, is the temple of the God whom they worship, becoming such from the pure conceptions which they entertain of the Creator, and who also, being careful not to corrupt the temple of God by unlawful pleasure; practise temperance as constituting piety towards God!

Origen of Alexandria, Origen Against Celsus 4.26

1692

Use four: Seeing you expect your bodies shall rise to glory, keep them unspotted from sin. Shall a drunken body rise to glory? Shall an unclean body rise to glory? … Your bodies are the members of Christ. Hear what the apostle says: ‘Shall I take the members of Christ, and make them the members of an harlot?

Thomas Watson, A Body of Divinity 7.3

1930–1933

The horror of deliberately taking "members of Christ" and making them "members of a harlot" in an actual union staggers Paul and should stagger us.

A.T. Robertson, Word Pictures in the New Testament 8.6

Lust, thoughts, and looks

11 passages · 11 writers · 1st c. to 1800s

Writers extend the prohibition to thoughts, looks, and desires, and urge guarding them.

c. 70–110

My child, flee from every evil thing, and from every likeness of it. … 3. My child, be not a lustful one; for lust leadeth the way to fornication; neither a filthy talker, nor of lofty eye; for out of all these adulteries are engendered.

The Teaching of the Twelve Apostles, The Teaching of the Twelve Apostles 3.3

c. 140–155

“I charge you,” said he, “to guard your chastity, and let no thought enter your heart of another man’s wife, or of fornication, or of similar iniquities; for by doing this you commit a great sin. But if you always remember your own wife, you will never sin. For if this thought enter your heart, then you will sin; and if, in like manner, you think other wicked thoughts, you commit sin.

Hermas, The Pastor of Hermas 3.4

c. 350–373

Even in seeing, thou mayest sin, if thy mind is not watchful; and in hearing thou mayest transgress, if thou dost not guard thy hearing. The fornicator’s heart waxes wanton through speech that is full of uncleanness. The passion hidden in the mind, sight and hearing awaken it.

Ephrem the Syrian, Ephraim Syrus:  Three Homilies 3

c. 425–429

But if a sudden thought or a passage of Holy Scripture brings up the recollection of a woman and we feel that we are at all attracted towards her, we should know that the fire of fornication is not yet extinguished in us. But if on a comparison of our own strictness with the laxity of another even the slightest conceit tries our mind, it is clear that we are affected with the dreadful plague of pride. When then we detect these signs of faults in our heart, we should clearly recognize that it is only the opportunity and not the passion of sin of which we are deprived.

Fornication compared with other sins

10 passages · 8 writers · 200s to 1800s

Writers rank fornication against adultery, polygamy, gluttony, and sins of the soul.

c. 250–400

The Fathers say nothing of polygamy as being beastly, and a thing unagreeable to human nature. To us it appears a greater sin than fornication: Let therefore such [as are guilty of it] be liable to the canons, viz.: after they have been mourners one year—let them be prostrators three years—and then be received

1674

It is a higher aggravation, when men in sinning abuse and dishonour their own bodies; for these are the principal external workmanship of God, being made for eternity, and whose preservation unto his glory is committed unto us in an especial manner. This the apostle declareth to be the peculiar aggravation of the sin of fornication, and uncleanness of any kind, 1 Cor. vi. 18, 19. But the height of impiety consists in the abuse of the faculties and powers of the soul, wherewith we are endowed purposely and immediately for the glorifying of God.

John Owen, Pneumatologia 6.8

1871

Fornication is nearly akin to gluttony, Esau's sin. He profanely cast away his spiritual privilege for the gratification of his palate.

The Acts 15 decree and the pagan setting

9 passages · 8 writers · 300s to 1900s

Writers explain why the apostles forbade fornication to Gentile converts and describe pagan and Corinthian attitudes.

375–380

Known unto God are all His works from the beginning of the world. Wherefore my sentence is, that we do not trouble those who from among the Gentiles turn unto God: but to charge them that they abstain from the pollutions of the Gentiles, and from what is sacrificed to idols, and from blood, and from things strangled, and from fornication; which laws were given to the ancients who lived before the law, under the law of nature, Enos , Enoch , Noah , Melchizedek , Job , and if there be any other of the same sort.”

Constitutions of the Holy Apostles, Constitutions of the Holy Apostles 7.3

393

Then, again, the Apostles and elders wrote letters from Jerusalem that no heavier burden should be laid on Gentile believers than that they should keep themselves from idolatry, and from fornication, and from things strangled. … For if the young man who boasted of having done all that the law enjoins, when he heard this went away sorrowful, because he had great possessions, and the Pharisees derided an utterance such as this from our Lord’s lips: how much more would the vast multitude of Gentiles, whose highest virtue consisted in not plundering another’s goods, have repudiated the obligation of perpetual chastity and continence, when they were told in the letter to keep themselves from idols, and from fornication, seeing that fornication was heard of among them, and such fornication as was not “even among the Gentiles.”

Jerome, Against Jovinianus 1

430–439

There are nevertheless some persons who, disregarding these precepts, suppose all fornication to be an indifferent matter; but contend about holy-days as if their lives were at stake, thus contravening the commands of God, and legislating for themselves, and making of none effect the decree of the apostles: neither do they perceive that they are themselves practicing the contrary to those things which God approved.

Socrates Scholasticus, The Ecclesiastical History of Socrates Scholasticus 8.23

1871

From such food James would enjoin the Gentile converts to abstain, lest it should seem to the Jews that they were not entirely weaned from idolatry. and from fornication—The characteristic sin of heathendom, unblushingly practiced by all ranks and classes, and the indulgence of which on the part of the Gentile converts would to Jews, whose Scriptures branded it as an abomination of the heathen, proclaim them to be yet joined to their old idols. and from things strangled—which had the blood in them.

Robert Jamieson, A.R. Fausset, and David Brown, Commentary Critical and Explanatory on the Whole Bible Acts 15

1930–1933

James agrees with Peter in his support of Paul and Barnabas in their contention for Gentile freedom from the Mosaic ceremonial law. The restrictions named by James affect the moral code that applies to all (idolatry, fornication, murder). Idolatry, fornication and murder were the outstanding sins of paganism then and now (Re 22:15 ).

Unmarried unions, betrothal, and seduction

9 passages · 9 writers · 100s to 1900s

Writers and canons treat intercourse before marriage, with betrothed women and unbetrothed virgins, as fornication or as binding the parties to marry.

c. 190–202

According to the opinion of the Stoics, marriage and the rearing of children are a thing indifferent; and according to the Peripatetics, a good. In a word, these, following out their dogmas in words, became enslaved to pleasures; some using concubines, some mistresses, and the most youths. And that wise quaternion in the garden with a mistress, honoured pleasure by their acts.

Clement of Alexandria, The Stromata, or Miscellanies 2.23

c. 250–400

If anyone shall force and keep a virgin not espoused, let him be excommunicated. And he may not take any other, but must retain her whom he has chosen, though she be a poor person.

c. 303–313

For it is not sufficient if you abstain from another’s bed, or from the brothel. Let him who has a wife seek nothing further, but, content with her alone, let him guard the mysteries of the marriage-bed chaste and undefiled. For he is equally an adulterer in the sight of God and impure, who, having thrown off the yoke, wantons in strange pleasure either with a free woman or a slave.

Lactantius, The Divine Institutes 8.62

1609

No unlawful pleasures are compatible with chastity; the pure heart is like the mother of pearl which admits no drop of water save that which comes from Heaven,—it is closed to every attraction save such as are sanctified by holy matrimony. Close your heart to every questionable tenderness or delight, guard against all that is unprofitable though it may be lawful, and strive to avoid unduly fixing your heart even on that which in itself is right and good.

Francis de Sales, Introduction to the Devout Life 3.12

Writers include fornication in the Decalogue, the Two Ways, and lists of vices.

c. 70–110

And the way of death is this: First of all it is evil and full of curse: murders, adulteries, lusts, fornications, thefts, idolatries, magic arts, witchcrafts, rapines, false witnessings, hypocrisies, double-heartedness, deceit, haughtiness, depravity, self-will, greediness, filthy talking, jealousy, over-confidence, loftiness, boastfulness;

c. 125–130

They have the commands of the Lord Jesus Christ Himself graven upon their hearts; and they observe them, looking forward to the resurrection of the dead and life in the world to come. They do not commit adultery nor fornication, nor bear false witness, nor covet the things of others; they honour father and mother, and love their neighbours; they judge justly, and they never do to others what they would not wish to happen to themselves; they appeal to those who injure them, and try to win them as friends; they are eager to do good to their enemies; they are gentle and easy to be entreated; they abstain from all unlawful conversation and from all impurity; they despise not the widow, nor oppress the orphan; and he that has, gives ungrudgingly for the maintenance of him who has not.

Aristides of Athens, The Apology of Aristides the Philosopher 3

c. 130–135

Thou shalt not allow over-boldness to enter into thy soul. Thou shalt not commit fornication: thou shalt not commit adultery: thou shalt not be a corrupter of youth. Thou shalt not let the word of God issue from thy lips with any kind of impurity.

Barnabas, Epistle of Barnabas 2.19

155–157

“For [God] sets before every race of mankind that which is always and universally just, as well as all righteousness; and every race knows that adultery, and fornication, and homicide, and such like, are sinful; and though they all commit such practices, yet they do not escape from the knowledge that they act unrighteously whenever they so do, with the exception of those who are possessed with an unclean spirit, and who have been debased by education, by wicked customs, and by sinful institutions, and who have lost, or rather quenched and put under, their natural ideas.

Justin Martyr, Dialog with Trypho 93

387

For we have no need to learn that fornication is an evil thing, and that chastity is a good thing, but we know this from the first.

Israel, Balaam, and Jezebel as warnings

6 passages · 6 writers · 100s to 1900s

Writers cite Israel's fornication, Balaam's counsel, and Jezebel's teaching as warnings.

180

“To inflict vengeance from the Lord on Midian.” For this man (Balaam), when he speaks no longer in the Spirit of God, but contrary to God’s law, by setting up a different law with regard to fornication, is certainly not then to be counted as a prophet, but as a soothsayer. For he who did not keep to the commandment of God, received the just recompense of his own evil devices.

Irenaeus of Lyons, Fragments from the Lost Writings of Irenæus 25

c. 362–389

Phineas was called Zelotes because he ran through the Midianitish woman with the man who was committing fornication with her, and because he took away the reproach from the children of Israel: but he was more praised because he prayed for the people when they had transgressed.

Gregory of Nazianzus, Select Letters of Saint Gregory Nazianzen 4.7.1

c. 386–407

“Neither let us commit fornication, as some of them committed.” … This then Paul also does here, at the same time both reminding them of that sin, and teaching that the parent of this evil also was luxury and gluttony. Wherefore also he adds, “Neither let us commit fornication, as some of them committed, and fell in one day three and twenty thousand.”

John Chrysostom, Homilies on First Corinthians 24

1755–1765

To teach and seduce my servants - At Pergamos were many followers of Balaam; at Thyatira, one grand deceiver. … This she seems to have done by first enticing them to fornication, just as Balaam did: whereas at Pergamos they were first enticed to idolatry, and afterwards to fornication.

John Wesley, Notes on the Bible 27.2

1871

What they had peculiarly to contend against at Pergamos was the temptation to idol-meats, and fornication, put in their way by Balaamites. As Phinehas was rewarded with "an everlasting priesthood" for his zeal against these very sins to which the Old Testament Balaam seduced Israel; so the heavenly high priesthood is the reward promised here to those zealous against the New Testament Balaamites tempting Christ's people to the same sins.

Robert Jamieson, A.R. Fausset, and David Brown, Commentary Critical and Explanatory on the Whole Bible Revelation 2

1930–1933

Balaam, as Josephus and Philo also say, showed Balak how to set a trap for the Israelites by beguiling them into the double sin of idolatry and fornication, which often went together (and do so still).
