Bede the Venerable
Catena Aurea · Markusevangelium 9
And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched: Where their worm dieth not, and the fire is not quenched. And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feet to be cast into hell, into the fire that never shall be quenched: Where their worm dieth not, and the fire is not quenched. And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire: Where their worm dieth not, and the fire is not quenched. For every one shall be salted with fire, and every sacrifice shall be salted with salt. Salt is good: but if the salt have lost his saltness, wherewith will ye season it? Have salt in yourselves, and have peace one with another.
(ubi sup.) A friend is called a foot, on account of its service in going about for us, since he is as it were ready for our use. It goes on: And if thine eye offend thee, pluck it out: it is better for thee to enter into the kingdom of God with one eye, than having two eyes to be cast into hell fire; where their worm dieth not, and the fire is not quenched. A friend who is useful, and anxious, and sharp in perception, is called an eye.
