Our Saviour here vindicates the sixth commandment, which obliges us to do no wrong to the body of our neighbour. God had given a law to the public magistrate, to require an eye for an eye, and a tooth for a tooth, when a person was wronged: hereupon the Pharisees taught, That a private person, wronged by another, might exact satisfaction from him to the same degree in which he had been wronged by him; if he had lost an eye by another, might revenge it, by taking away the eye of another.
But, says Christ, I say unto you, resist not evil; that is, seek not private revenge, but leave the avenging of injuries to God and the magistrates; and in trivial matters not to appeal at all, and, when forced, not for revenge sake: teaching us, That Christians ought rather to suffer a double wrong, than to seek a private revenge. Christianity obliges us to bear many injuries patiently, rather than to revenge one privately. Religion indeed doth not bid them welcome: we are not to return evil for evil, but are rather to endure a greater evil than to revenge a less.
