And if your right hand causes you to offend, cut it off, and cast it from you: for it is better for you that one of your members should perish, and not that your whole body should be cast into hell.
All Commentaries on Matthew 5:30 Go To Matthew 5
John Chrysostom
AD 407
Otherwise; Christ would have us careful not only of our own sin, but likewise that even they who pertain to us should keep themselves from evil. Have you any friend who looks to your matters as your own eye, or manages them as your own hand, if you know of any scandalous or base action that he has done, cast him from you, he is an offence; for we shall give account not only of our own sins, but also of such of those of our neighbours as it is in our power to hinder.
The eye of flesh is the mirror of the inward eye. The body also has its own sense, that is, the left eye, and its own appetite, that is, the left hand. Butthe parts of the soul are called right, for the soul was created both with free-will and under the law of righteousness, that it might both see and dorightly.But the members of the body being not with free-will, but under the law of sin, are called the left. Yet He does not bidus cut off the sense or appetite of the flesh; we may retain the desires of the flesh, and yet not do thereafter, but we cannot cut off the having the desires. But when we wilfully purpose and think of evil, then our right desires and right will offend us, and therefore He bids us cut them off. And these we can cut off, because our will is free. Or otherwise; Every thing, however good in itself that offends ourselves or others, we ought to cut off from us. For example, to visit a woman with religious purposes, this good intent towards her may becalled a right eye, but if often visiting her I have fallen into the net of desire, or if any looking on are offended, then the right eye, that is, something in itself good, offends me. For the “right eye” is good intention, the “right hand” is good desire.
