Augustine of Hippo
Catena Aurea · Matthäusevangelium 5
Ye have heard that it hath been said, An eye for an eye, and a tooth for a tooth: But I say unto you, That ye resist not evil: but whosoever shall smite thee on thy right cheek, turn to him the other also. And if any man will sue thee at the law, and take away thy coat, let him have thy cloak also. And whosoever shall compel thee to go a mile, go with him twain. Give to him that asketh thee, and from him that would borrow of thee turn not thou away.
(Epist. 185. 5.) But who that is of sober mind would say to kings, It is nothing of your concern who will live religiously, or who profanely? It cannot even be said to them, that it is not their concern who will live chastely, or who unchastely. It is indeed better that men should be led to serve God by right teaching than by penalties; yet has it benefitted many, as experience has approved to us, to be first coerced by pain and fear, that they might be taught after, or to be made to conform in deed to what they had learned in words. The better men indeed are led of love, but the more part of men are wrought on by fear. Let them learn in the case of the Apostle Paul, how Christ first constrained, and after taught him.
