Matthew 18:6

Mystically; The work of the mill is a toil of blindness, for the beasts having their eyes closed are driven round in a circle, and under the type of an ass we often find the Gentiles figured, who are held in the ignorance of blind labour; while the Jews have the path of knowledge set before them in the Law, who if they offend Christ's Apostles it were better for them, that having their necks made fast to a mill-stone, they should be drowned in the sea, that is, kept under labour and in the depths of ignorance, as the Gentiles; for it were better for them that they should have never known Christ, than not to have received the Lord of the Prophets.

After this, to obtain yet more acceptance for His saying, He establishes it not by the honor only, but also by the punishment, going on to say, "And whoso shall offend one of these little ones, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea." "For as they," saith He, "who honor these for my sake, have heaven, or rather an honor greater than the very kingdom; even so they likewise who dishonor them (for this is to offend them), shall suffer the extremity of punishment. And marvel thou not at His calling the affront "an offense;" for many feeble-minded persons have suffered no ordinary offense from being treated with slight and insult. To heighten therefore and aggravate the blame, He states the mischief arising therefrom. And He doth not go on to express the punishment in the same way, but from the things familiar to us, He indicates how intolerable it is. For when He would touch the grosser sort most sharply, He brings sensible images. Wherefore here also, meaning to indicate the greatness of the punishment they shall undergo, and to strike into the arrogance of those that despise them, He brought forward a kind of sensible punishment, that of the millstone, and of the drowning. Yet surely it were suitable to what had gone before to have said, "He that receiveth not one of these little ones, receivoth not me;" a thing bitterer than any punishment; but since the very unfeeling, and exceeding gross, were not so much penetrated by this, terrible as it is, He puts "a millstone," and "a drowning." And He said not, "A millstone shall be hanged about his neck," but, "It were better for him" to undergo this; implying that another evil, more grievous than this, awaits him; and if this be unbearable, much more that. Seest thou how in both respects He made His threat terrible, first by the comparison with the known image rendering it more distinct, then by the excess on its side presenting it to the fancy as far greater than that visible one. Seest thou how He plucks up by the root the spirit of arrogance; how He heals the ulcer of vainglory; how He instructs us in nothing to set our heart on the first honors; how He persuades such as covet them in everything to follow after the lowest place?

Observe that he who is offended is a little one, for the greater hearts do not take offences. And though it may be a general declaration against all who scandalize any, yet from the connection of the discourse it may be said specially to the Apostles; for in asking who should be greatest in the kingdom of heaven, they seemed to be contending for preeminence among themselves; and if they had persisted in this fault, they might have scandalized those whom they called to the faith, seeing the Apostles contending among themselves for the preference. When it is said, It is better for him that a mill-stone be hanged about his neck, He speaks according to the custom of the province; for among the Jews this was the punishment of the greater criminals, to drown them by a stone tied to them. It is better for him, because it is far better to receive a brief punishment for a fault, than to be reserved for eternal torments.

(Quaest. Ev. i. 24) Otherwise; Whoso offendeth one of these little ones, that is so humble as He would have his disciples to be, by not obeying, or by opposing, (as the Apostle says of Alexander,) it were better for him, that a millstone should be hanged about his neck, and he be drowned in the depths of the sea, (2 Tim. 4:15.) that is, it were better for him that desire of the things of the world, to which the blind and foolish are tied down, should sink him by its load to destruction.

(Mor. vi. 37.) Otherwise; What is denoted by the sea, but the world, and what by the mill-stone, but earthly action? which, when it binds the neck in the yoke of vain desires, sends it to a dull round of toil. There arc some who leave earthly action, and bond themselves to aims of contemplation beyond the reach of intellect, laying aside humility, and so not only throw themselves into error, but also cast many weak ones out of the bosom of truth. Whoso then offends one of the least of mine, it were better for him that a mill-stone be tied about his neck, and he be cast into the sea; that is, it were better for a perverted heart to be entirely occupied with worldly business, than to be at leisure for contemplative studies to the hurt of many.
