NT Apocrypha/Pseudepigrapha

Martyrdom of Bartholomew 1:9

And when the Lord had conquered the tyrant, He sent His apostles into all the world, that He might redeem His people from the deception of the devil; and one of these I am, an apostle of Christ. On this account we seek not after gold and silver, but rather despise them, because we labour to be rich in that place where the kingdom of Him alone endures for ever, where neither trouble, nor grief, nor groaning, nor death, has place; where there is eternal blessedness, and ineffable joy, and everlasting exultation, and perpetual repose. Wherefore also the demon sitting in your temple, who makes responses to you, is kept in chains through the angel of the Lord who has sent me. Because if you shall be baptized, and wish yourself to be enlightened, I will make you behold Him, and learn from how great evils you have been redeemed. At the same time hear also by what means he injures all those who are lying sick in the temple. The devil himself by his own art causes the men to be sick, and again to be healed, in order that they may the more believe in the idols, and in order that he may have place the more in their souls, in order that they may say to the stock and the stone, You are our God. But that demon who dwells in the idol is held in subjection, conquered by me, and is able to give no response to those who sacrifice and pray there. And if you wish to prove that it is so, I order him to return into the idol, and I will make him confess with his own mouth that he is bound, and able to give no response.

Apostolic Constitutions, Book I 2:1

But if any one curse you, bless him. For it is written in the book of Numbers: He that blesses you is blessed, and he that curses you is cursed. In the same manner it is written in the Gospel: Bless those who curse you. Being injured, do not avenge yourselves, but bear it with patience; for the Scripture speaks thus: Say not, I will avenge myself on my enemy for what injuries he has offered me; but acquiesce under them, that the Lord may right you, and bring vengeance upon him who injures you. For so says He again in the Gospel: Love your enemies, do good to those who hate you, and pray for them which despitefully use you and persecute you; and you shall be the children of your Father which is in heaven: for He makes His sun to shine on the evil and on the good, and rains on the just and unjust. Let us therefore, beloved, attend to these commandments, that we may be found to be the children of light by doing them. Bear, therefore, with one another, you servants and sons of God.

The Writings of Origen

Against Celsus, Book VII 58:1

Let us now consider what follows. “They have also,” says he, “a precept to this effect, that we ought not to avenge ourselves on one who injures us, or, as he expresses it, ‘Whosoever shall strike thee on the one cheek, turn to him the other also.’ This is an ancient saying, which had been admirably expressed long before, and which they have only reported in a coarser way. For Plato introduces Socrates conversing with Crito as follows: ‘Must we never do injustice to any?’ ‘Certainly not.’ ‘And since we must never do injustice, must we not return injustice for an injustice that has been done to us, as most people think?’ ‘It seems to me that we should not.’ ‘But tell me, Crito, may we do evil to any one or not?’ ‘Certainly not, O Socrates.’ ‘Well, is it just, as is commonly said, for one who has suffered wrong to do wrong in return, or is it unjust?’ ‘It is unjust. Yes; for to do harm to a man is the same as to do him injustice.’ ‘You speak truly. We must then not do injustice in return for injustice, nor must we do evil to any one, whatever evil we may have suffered from him.’ Thus Plato speaks; and he adds, ‘Consider, then, whether you are at one with me, and whether, starting from this principle, we may not come to the conclusion that it is never right to do injustice, even in return for an injustice which has been received; or whether, on the other hand, you differ from me, and do not admit the principle from which we started. That has always been my opinion, and is so still.’ Such are the sentiments of Plato, and indeed they were held by divine men before his time. But let this suffice as one example of the way in which this and other truths have been borrowed and corrupted. Any one who wishes can easily by searching find more of them.”
