John Chrysostom
Catena Aurea · Lukasevangelium 6
But I say unto you which hear, Love your enemies, do good to them which hate you, Bless them that curse you, and pray for them which despitefully use you. And unto him that smiteth thee on the one cheek offer also the other; and him that taketh away thy cloke forbid not to take thy coat also. Give to every man that asketh of thee; and of him that taketh away thy goods ask them not again. And as ye would that men should do to you, do ye also to them likewise. It follows, Bless them that curse you.
(Hom. 18. in Matt.) For physicians also, when they are attacked by madmen, have then most compassion on them, and exert themselves to restore them. Have thou also a like consideration towards thy persecutors; for it is they who are under the greatest infirmity. And let us not cease until they have exhausted all their bitterness, they will then overpower thee with thanks, and God Himself will give thee a crown, because thou hast delivered thy brother from the worst disease.
