Hilary of Poitiers
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.
Thus a more lofty step of innocence is appointed us, in that we are admonished to keep free, not only from sin ourselves, but from such as might touch as from without.
