Matthew 3:5

The preacher of Christ is clad in the skins of unclean beasts, to which the Gentiles are compared, and so by the Prophets' dress is sanctified whatever in them was useless or unclean. The girdle is a thing of much efficacy to every good work, that we may be girt for every ministry of Christ. For his food are chosen locusts, which fly the face of man, and escape from every approach, signifying ourselves who were borne away from every word or speech of good by a spontaneous motion of the body, weak in will, barren in works, fretful in speech, foreign in abode, are now become the food of the Saints, chosen to fill the Prophets' desire, furnishing our most sweet food not from the hives of the law, but from the trunks of wild trees.

"Then went out to him all Judea, and Jerusalem, and all the region round about Jordan, and were baptized of him, confessing their sins." Seest thou how great power was in the coming of the prophet? how he stirred up all the people; how he led them to a consideration of their own sins? For it was indeed worthy of wonder to behold him in human form showing forth such things and using so great freedom of speech, and rising up in condemnation of all as children, and having his great grace beaming out from his countenance. And, moreover, the appearance of a prophet after the great interval of time contributed to their amazement, because the gift had failed them, and returned to them after a long time. And the nature of his preaching too was strange and unusual. For they heard of none of those things to which they were accustomed; such as wars and battles and victories below, and famine and pestilence, and Babylonians and Persians, and the taking of the city, and the other things with which they were familiar, but of Heaven and of the kingdom there, and of the punishment in hell. And it was for this cause, let me add, that although they that committed revolt in the wilderness, those in the company of Judas, and of Theudas, had been all of them slain no great while before, yet they were not the more backward to go out thither. For neither was it for the same objects that he summoned them, as for dominion, or revolt, or revolution; but in order to lead them by the hand to the kingdom on high. Wherefore neither did he keep them in the wilderness, to take them about with him, but baptizing them, and teaching them the rules concerning self-denial, he dismissed them; by all means instructing them to scorn whatever things are on earth, and to raise themselves up to the things to come, and press on every day. This man then let us also emulate, and forsaking luxury and drunkenness let us go over unto the life of restraint. For this surely is the time of confession both for the uninitiated and for the baptized; for the one, that upon their repentance they may partake of the sacred mysteries; for the others, that having washed away their stain after baptism, they may approach the table with a clean conscience. Let us then forsake this soft and effeminate way of living. For it is not, it is not possible at once both to do penance and to live in luxury. And this let John teach you by his raiment, by his food, by his abode. What then? dost thou require us, you may say, to practise such self-restraint as this? I do not require it, but I advise and recommend it. But if this be not possible to you, let us at least, though in cities, show forth repentance, for the judgment is surely at our doors. But even if it were further off, we ought not even so to be emboldened, for the term of each man's life is the end of the world visually to him that is summoned.

Having described the preaching of John, he goes on to say, There went out to him, for his severe life preached yet more loudly in the desert than the voice of his crying. Compared with the holiness of John, who is there that can think himself righteous? As a white garment if placed near snow would seem foul by the contrast; so compared with John every man would seem impure; therefore they confessed their sins. Confession of sin is the testimony of a conscience fearing God. And perfect fear takes away all shame. But there is seen the shame of confession where there is no fear of the judgment to come. But as shame itself is a heavy punishment, God therefore bids us confess our sins that we may suffer this shame as punishment; for that itself is a part of the judgment.

The baptism of John bare a figure of the catechumens. As children are only catechized that they may become meet for the sacrament of Baptism; so John baptized, that they who were thus baptized might afterwards by a holy life become worthy of coming to Christ's baptism. He baptized in Jordan, that the door of the Kingdom of Heaven might be there opened, where an entrance had been given to the children of Israel into the earthly kingdom of promise.

Rightly are they who are to be baptized said to go out to the Prophet; for unless one depart from sin, and renounce the pomp of the Devil, and the temptations of the world, he cannot receive a healing baptism. Rightly also in Jordan, which means their descent, because they descended from the pride of life to the humility of an honest confession. Thus early was an example given to them that are to be baptized of confessing their sins and professing amendment.
