Pseudo-Chrysostom
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.
(v. Vict. Ant. in Cat.) Or, according to Matthew, the disciples of Christ are the salt, which preserves the whole world, resisting the rottenness which proceeds from idolatry and sinful fornication. For it may also be meant, that each of us has salt, in as far as he contains in himself the graces of God. Wherefore also the Apostle joins together grace and salt, saying, Let your speech be always with grace, seasoned with salt. (Col. 4:6) For salt is the Lord Jesus Christ, Who was able to preserve the whole earth, and made many to be salt in the earth: and if any of these be corrupted, (for it is possible for even the good to be changed into corruption,) they are worthy to be cast out.
