Mark 9:45

(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.

But those who hold that both of these, namely, the fire and the worm, belong to the pains of the soul, and not of the body, say also that those who are separated from the kingdom of God are tortured, as with fire, by the pangs of a soul, repenting too late, and hopelessly; and they not unfitly contend that fire may be put for that burning grief, as says the Apostle, Who is offended, and I burn not? (2 Cor. 11:29) They also think that by the worm must be understood the same grief, as is said: As a moth destroys a garment, and a worm wood, so grief tortures the heart of man. (Prov. 25:20. vulg.) All those who hesitate not to affirm that there will be pain both of body and soul in that punishment, affirm that the body is burnt by the fire. But although this is more credible, because it is absurd that there either the pains of body or of soul should be wanting, still I think that it is easier to say that both belong to the body than that neither; and therefore it seems to me that Holy Scripture in this place is silent about the pains of the soul, because it follows that the soul also is tortured in the pains of the body. Let each man therefore choose which he will, either to refer the fire to the body, the worm to the soul, the one properly, the other in a figure, or else both properly to the body; for living things may exist even in fire, in burnings without being wasted, in pain without death, by the wondrous power of the Almighty Creator. It goes on: And if thy foot offend thee, cut it off: it is better for thee to enter halt into life, than having two feel to be cast into hell, into the fire that never shall be quenched; where their worm, dieth not, and the fire is not quenched.

Here truly it appears that they who do acts of devotedness in the name of Christ, even before they have joined themselves to the company of Christians, and have been washed in the Christian Sacraments, are more useful than those who though already bearing the name of Christians, by their doctrine drag their followers with themselves into everlasting punishment; whom also under the name of members of the body, He orders, as an offending eye or hand, to be torn from the body, that is, from the fellowship itself of unity, that we may rather come to everlasting life without them, than with them go into hell. But the separation of those who separate themselves from them consists in the very circumstance of their not yielding to them, when they would persuade them to evil, that is, offend them. If indeed their wickedness becomes known to all the good men, with whom they are connected, they are altogether cut off from all fellowship, and even from partaking in the heavenly Sacraments. If however they are thus known only to the smaller number, whilst their wickedness is unknown to the generality, they are to he tolerated in such a way that we should not consent to join in their iniquity, and that the communion of the good should not be deserted on their account.

Mark relates that the Lord said these things consecutively, and has put down some things omitted by every other Evangelist, some which Matthew has also related, others which both Matthew and Luke relate, but on other occasions, and in a different series of events. Wherefore it seems to me that our Lord repeated in this place discourses which He had used in other places, because they were pertinent enough to this saying of His, by which He prevented their forbidding miracles to be wrought in His name, even by him who followed Him not together with His disciples.
