Abba Poemen : "What does 'See that none of you repays evil for evil' mean?" The old man said … 'Passions work in four stages—first, in the heart; secondly, in the face; thirdly, in words; and fourthly, it is essential not to render evil for evil in deeds. If you can purify your heart, passion will not come into your expression; but if it comes into your face, take care not to speak; but if you do speak, cut the conversation short in case you render evil for evil.' " — SAYINGS OF THE FATHERS 34 Desert Fathers : A brother asked Poemen about the words, 'Do not render evil for evil' (1 Thess. 5:15). He said to him, 'The passions work in four stages: first in the heart, then in the face, third in words, fourth in deeds – and it is in deeds that it is essential not to render evil for evil. If you purify your heart, passion will not show in your expression, but if it does, take care not to speak about it; if you do speak, cut the conversation short in case you render evil for evil.' — The Desert Fathers, Sayings of the Early Christian Monks John Chrysostom : "See that none render unto any one evil for evil; but alway follow after that which is good, one toward another, and toward all." If we ought not to render evil for evil, much less evil for good; much less, when evil has not been previously done, to render evil. Such an one, you say, is a bad man, and has aggrieved me, and done me much injury. Do you wish to revenge yourself upon him? Do not retaliate. Leave him unpunished. Well, is this the stopping-place? By no means; "But alway follow after that which is good, one toward another, and toward all." This is the higher philosophy, not only not to requite evil with evil, but to render good for evil. For this is truly revenge that brings harm to him and advantage to thyself, or rather great advantage even to him, if he will. And that thou mayest not think that this is said with respect to the faithful, therefore he has said, "both one toward another and toward all." — Homily on 1 Thessalonians 10
