Matthew 3:12

Then, as having uttered the gentler part of his message, and soothed and relaxed the hearer, he again binds him up, that he may not become remiss. For such was the nature of the Jewish nation; by all encouraging things they were easily puffed up, and corrupted. Wherefore he again adduces his terrors, saying, "Whose fan is in His hand." Thus, as before he had spoken of the punishment, so here he points out the Judge likewise, and introduces the eternal vengeance. For "He will burn the chaff," saith he, "with unquenchable fire." Thou seest that He is Lord of all things, and that He is Himself the Husbandman; albeit in another place He calls His Father the same. For "My Father," saith He, "is the Husbandman." Thus, inasmuch as He had spoken of an axe, lest thou shouldest suppose that the thing needed labor, and the separation was hard to make; by another comparison he suggests the easiness of it, implying that all the world is His; since He could not punish those who were not His own. For the present, it is true, all are mingled together (for though the wheat appears gleaming through, yet it lies with the chaff, as on a threshing floor, not as in a garner), but then, great will be the separation. Where now are they by whom hell-fire is disbelieved? Since surely here are two points laid down, one, that He will baptize with the Holy Ghost, the other, that He will burn up the disobedient. If then that is credible, so is this too, assuredly. Yea, this is why the two predictions are put by him in immediate connection, that by that which hath taken place already, he might accredit the other, as yet unaccomplished. For Christ too Himself in many places doth so, often of the same things, and often of opposites, setting down two prophecies; the one of which He performs here, the other He promises in the future; that such as are too contentious may, from the one which has already come to pass, believe the other also, which is not yet accomplished.

For instance, to them that strip themselves of all that they have for His sake He promised to give an hundred fold in the present world, and life eternal in that which is to come; by the things already given making the future also credible. Which, as we see, John likewise hath done in this place; laying down two things, that He shall both baptize with the Holy Ghost, and burn up with unquenchable fire. Now then, if He had not baptized with the Spirit the apostles, and all every day who are willing, thou mightest have doubts concerning those other things too; but if that which seems to be greater and more difficult, and which transcends all reason, hath been done, and is done every day; how deniest thou that to be true, which is easy, and comes to pass according to reason? Thus having said, "He shall baptize with the Holy Ghost and with fire," and having thence promised great blessings; lest thou, released wholly from the former things, grow supine, he hath added the fan, and the judgment thereby declared. Thus, "think not at all," saith he, "that your baptism suffices, if ye become ordinary persons hereafter:" for we need both virtue, and plenty of that known self-restraint. Therefore as by the axe he urges them unto grace, and unto the font, so after grace he terrifies them by the fan, and the unquenchable fire. And of the one sort, those yet unbaptized, he makes no distinction, but saith in general "Every tree that bringeth not forth good fruit is hewn down," punishing all the unbelievers. Whereas after baptism He works of their faith.

Let no man then become chaff, let no one be tossed to and fro, nor lie exposed to wicked desires, blown about by them easily every way. For if thou continue wheat, though temptation be brought on thee, thou wilt suffer nothing dreadful; nay, for in the threshing floor, the wheels of the car, that are like saws, do not cut in pieces the wheat; but if thou fall away into the weakness of chaff, thou wilt both here suffer incurable ills, being smitten of all men, and there thou wilt undergo the eternal punishment. For all such persons both before that furnace become food for the irrational passions here, as chaff is for the brute animal: and there again they are material and food for the flame. Now to have said directly that He will judge men's doings, would not so effectually procure acceptance for His doctrine: but to blend with it the parable, and so establish it all, was apter to persuade the hearer, and part so discourses with them; threshing floor, and harvest, and vineyard, and wine-press, and field, and net, and fishing, and all things familiar, and among which they were busied He makes ingredients in His discourses. This kind of thing then the Baptist likewise did here, and offered an exceeding great demonstration of his words, the giving of the Spirit. For "He who hath so great power, as both to forgive sins, and to give the Spirit, much more will these things also be within His power:" so he speaks.

Therefore, knowing these things, let us use great diligence, while we are in the threshing floor; for it is possible while we are here, to change even out of chaff into wheat, even as on the other hand many from wheat have become chaff. Let us not then be supine, nor be carried about with every wind; neither let us separate ourselves from our brethren, though they seem to be small and mean; forasmuch as the wheat also compared with the chaff is less in measure, but better in nature. Look not therefore to the forms of outward pomp, for they are prepared for the fire, but to this godly humility, so firm and indissoluble, and which cannot be cut, neither is burnt by the fire. It being for their sake that He bears long with the very chaff, that by their intercourse with them they may become better. Therefore judgment is not yet, that we may be all crowned together, that from wickedness many may be converted unto virtue. Let us tremble then at hearing this parable. For indeed that fire is unquenchable. "And how," it may be said, "is it unquenchable?" Seest thou not this sun ever burning, and never quenched? didst thou not behold the bush burning, and not consumed? If then thou also desirest to escape the flame, lay up alms beforehand, and so thou wilt not even taste of that fire. For if, while here, thou wilt believe what is told thee, thou shalt not so much as see this furnace, after thy departure into that region; but if thou disbelieve it now, thou shalt know it there full well by experience, when no sort of escape is possible. Since in truth no entreaty shall avert the punishment from them who have not shown forth an upright life. For believing surely is not enough, since even the devils tremble at God, but for all that they will be punished.

What then, if the tares should remain until the end? "Then I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them." He again reminds them of John's words, introducing Him as judge; and He saith, So long as they stand by the wheat, we must spare them, for it is possible for them even to become wheat; but when they have departed, having profited nothing, then of necessity the inexorable punishment will overtake them.
