Matthew 18:8

Or, The priests may with good reason be called the eyes of the Church, since they are considered her watchmen, but the deacons and the rest her hands, for by them spiritual deeds are wrought; the people are the feet of the body, the Church; and all these it behoves not to spare, if they become an offence to the Church. Or, by the offending hand is understood an act of the mind; a motion of the mind is the offending foot, and a vision of the mind is the sinning eye, which we ought to cut off if they give offence, for thus the acts of the limbs are often put in Scripture for the limbs themselves.

But that you may learn that there is no absolute necessity for offences, hear what follows, If thy hand or thy foot offend thee, & c. This is not said of the limbs of the body, but of friends whom we esteem as limbs necessary to us; for nothing is so hurtful as evil communications.

So all affection, our whole kindred, are severed from us; lest under cover of duty any believer should be exposed to offence. If, He says, he be united to thee as close as is thy hand, or foot, or eye, and is useful to thee, anxious and quick to discern, and yet causes thee offence, and is by the unmeetness of his behaviour drawing thee into hell; it is better for thee that thou lack his kindred, and his profitableness to thee, than that whilst thou seekest to gain thy kindred or friends, thou shouldest have cause of fallings. For every believer knows what is doing him harm, what troubles and tempts him, for it is better to lead a solitary life, than to lose eternal life, in order to have the things necessary for this present life.

But let us tear these in pieces not by our words only, but by our deeds too. For neither are these things of necessity. For if they were of necessity, He would not have said, "Woe to the man, by whom the offense cometh." For those only doth he bewail, who are wicked by their choice. And if He saith "by whom," marvel not. For not as though another were bringing in it by him, doth He say this, but viewing him as himself causing the whole. For the Scripture is wont to say, "by whom," for "of whom;" as when it saith, "I have gotten a man by God," putting not the second cause, but the first; and again, "Is not the interpretation of them by God," and, "God is faithful, by whom ye are called unto the fellowship of His Son." And that thou mayest learn that it is not of necessity, hear also what follows. For after bewailing them, He saith, "If thy hand, or thy foot offend thee, cut them off, and cast them from thee: for it is better for thee to enter into life halt or maimed, rather than having two hands or feet to be cast into the fire. And if thy right eye offend thee, pluck it out; it is better for thee to enter into life with one eye, than having two eyes to be cast into the furnace of fire;" not saying these things of limbs; far from it; but of friends, of relations, whom we regard in the rank of necessary members. This He had both said further back, and now He saith it. For nothing is so hurtful as bad company. Wherefore with much earnestness He commands us to cut off them that hurt us, intimating these that bring the offenses. Seest thou how He hath put away the mischief that would result from the offenses? By foretelling that there surely will be offenses, so that they might find no one in a state of carelessness, but that looking for them men might be watchful. By showing the evils to be great (for He would not have said without purpose, "Woe to the world because of the offenses," but to show that great is the mischief therefrom), by lamenting again in stronger terms over him that brings them in. For the saying, "But woe to that man," was that of one showing that great was the punishment, but not this only, but also by the comparison which He added He increased the fear. Then He is not satisfied with these things, but He showeth also the way, by which one may avoid the offenses. But what is this? The wicked, saith He, though they be exceeding dear friends to thee, cut off from thy friendship. And He giveth a reason that cannot be gainsaid. For if they continue friends, thou wilt not gain them, but thou wilt lose thyself besides; but if thou shouldest cut them off, thine own salvation at least thou wilt gain. So that if any one's friendship harms thee, cut it off from thee. For if of our own members we often cut off many, when they are both in an incurable state, and are ruining the rest, much more ought one to do this in the case of friends. But if evils were by nature, superfluous were all this admonition and advice, superfluous the precaution by the means that have been mentioned. But if it be not superfluous, as surely it is not superfluous, it is quite clear that wickedness is of the will.
