Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 5
And if thy right eye offend thee, pluck it out, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell. And if thy right hand offend thee, cut it off, and cast it from thee: for it is profitable for thee that one of thy members should perish, and not that thy whole body should be cast into hell.
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.
