c. 197–220
Satan will not be at liberty to do anything against the servants of the living God unless the Lord grant leave, either that He may overthrow Satan himself by the faith of the elect which proves victorious in the trial, or in the face of the world show that apostatizers to the devil’s cause have been in reality His servants. You have the case of Job, whom the devil, unless he had received authority from God, could not have visited with trial, not even, in fact, in his property, unless the Lord had said, “Behold, all that he has I put at your disposal; but do not stretch out your hand against himself.” In short, he would not even have stretched it out, unless afterwards, at his request, the Lord had granted him this permission also, saying, “Behold, I deliver him to you; only preserve his life.” So he asked in the case of the apostles likewise an opportunity to tempt them, having it only by special allowance, since the Lord in the Gospel says to Peter, “Behold, Satan asked that he might sift you as grain; but I have prayed for you that your faith fail not;” that is, that the devil should not have power granted him sufficient to endanger his faith.
Tertullian, De Fuga in Persecutione 1
