Matthew 3:3

The voice is a confused sound, discovering no secret of the heart, only signifying that he who utters it desires to say somewhat; it is the word that is the speech that openeth the mystery of the heart. Voice is common to men and other animals, word peculiar to man. John then is called the voice and not the word, because God did not discover His counsels through him, but only signified that He was about to do something among men; but afterwards by His Son he fully opened the mystery of his will. As a great King going on a progress is preceded by couriers to cleanse what is foul, repair what is broken down; so John preceded the Lord to cleanse the human heart from the filth of sin, by the besom of repentance, and to gather by an ordinance of spiritual precepts those things which had been scattered abroad.

Conceive, for example, how great a thing it was to see a man after thirty years coming down from the wilderness, being the son of a chief priest, who had never known the common wants of men, and was on every account venerable, and had Isaiah with him. For he too was present proclaiming him, and saying, "This is he who I said should come crying, and preaching throughout the whole wilderness with a clear voice." For so great was the earnestness of the prophets touching these things, that not their own Lord only, but him also who was to minister unto Him, they proclaimed a long time beforehand, and they not only mentioned him, but the place too in which he was to abide, and the manner of the doctrine which he had to teach when he came, and the good effect that was produced by him. See, at least, how both the prophet and the Baptist go upon the same ideas, although not upon the same words. Thus the prophet saith that he shall come saying, "Prepare ye the way of the Lord, make his paths straight." And he himself when he was come said, "Bring forth fruits meet for repentance," which corresponds with, "Prepare ye the way of the Lord." Seest thou that both by the words of the prophet, and by his own preaching, this one thing is manifested alone; that he was come, making a way and preparing beforehand, not bestowing the gift, which was the remission, but ordering in good time the souls of such as should receive the God of all? But Luke expresses somewhat further: not repeating the exordium, and so passing on, but setting down likewise all the prophecy. "For every valley," saith he, "shall be filled; and every mountain and hill shall be brought low; and the crooked shall be made straight, and the rough ways smooth; and all flesh shall see the salvation of God." Dost thou perceive how the prophet hath anticipated all by his words; the concourse of the people. […]

(De Cons. Ev. ii. 12.) The other Evangelists omit these words of John. What follows, This is He, &c. it is not clear whether the Evangelist speaks them in his own person, or whether they are part of John's preaching, and the whole from Repent ye, to Esaias the prophet, is to be assigned to John. It is of no importance that he says, This is he, and not, I am he; for Matthew speaking of himself says, He found a man sitting at the toll-office; (Mat. 9:9.) not He found me. Though when asked what he said of himself, he answered, as is related by John the Evangelist, I am the voice of one crying in the wilderness.

"I am the voice of one crying in the wilderness: Make straight the way of the Lord, as Isaiah the prophet said." You know, dearest brothers, that the only-begotten Son is called the Word of the Father, as John testifies when he says: "In the beginning was the Word, and the Word was with God, and the Word was God." And from your own manner of speaking you recognize that the voice sounds first, so that the word may afterward be heard. Therefore John asserts that he is the voice, because he precedes the Word. And so, going before the coming of the Lord, he is called a voice, because through his ministry the Word of the Father is heard by men. He also cries out in the wilderness, because he announces the comfort of the Redeemer to abandoned and forsaken Judea. But what he cries out he indicates when he adds: "Make straight the way of the Lord." The way of the Lord is made straight to the heart when the word of truth is humbly heard. The way of the Lord is made straight to the heart when one's life is prepared according to his commandment.

As it is written in the book of the words of Isaiah the prophet: The voice of one crying in the wilderness, Prepare the way of the Lord, make his paths straight. Indeed, the same John the Baptist, when asked who he was, answered, saying: I am the voice of one crying in the wilderness. He, as was said by us before, was called a voice by the prophet because he preceded the Word. But what he cried out is revealed when it is added: Prepare the way of the Lord, make his paths straight. Everyone who preaches right faith and good works, what else does he do but prepare a way for the coming Lord into the hearts of his hearers? So that the power of grace may penetrate, so that the light of truth may illuminate, so that he may make straight paths for God, while he forms pure thoughts in the mind through the word of good preaching.

(Hom. in Ev. i. 7. 2.) It is well known that the Only-begotten Son is called the Word of the Father; as in John, In the beginning was the Word. (John 1:1.) But it is by our own speech that we are known; the voice sounds that the words may be heard. Thus John the forerunner of the Lord's coming is called, The voice, because by his ministry the voice of the Father is heard by men.

(Hom. in Ev. i. 7. 2.) Crying in the desert, because he shows to deserted and forlorn Judæa the approaching consolation of her Redeemer.

(Hom. in Ev. i. 20. 3.) Every one who preacheth right faith and good works, prepares the Lord's way to the hearts of the hearers, and makes His paths straight, in cleansing the thoughts by the word of good preaching.

Then this preaching is confirmed: "This is he who was spoken of by the prophet Isaiah..." And, as Augustine says, this can be explained in two ways: first, so that the words, "This is he who was spoken of," are the words of the evangelist; …

(Gloss. ord. in cap. iv. 1.) In like manner has He cried from the beginning through the voice of all who have spoken aught by inspiration. And yet is John only called, The voice; because that Word which others showed afar off, he declares as nigh.

He is rightly called, The voice of one crying, on account of the loud sound of his preaching. Three things cause a man to speak loud; when the person he speaks to is at a distance, or is deaf, or if the speaker be angry; and all these three were then found in the human race.

(ord.) John then is, as it were, the voice of the word crying. The word is heard by the voice, that is, Christ by John. (interlin.) Or, faith is the way by which the word reaches the heart; when the life is amended the paths are made straight.

For this is he that was spoken of by the prophet Isaiah, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make His paths straight (Is. 40:3). "The way," that is, the highway, means the Gospel. The "paths" …

For this is he that was spoken of,.... These are not the words of the Baptist himself, as in Joh 1:23 but of the Evangelist, who cites and applies to John a passage in the Prophet Isaiah, Isa 40:3 and that very pertinently, since that "chapter" is a prophecy of the Messiah. The consolations spoken of in Isa 40:3, were to be in the days of the king Messiah, as a writer of note (y) among the Jews observes.

Gates of brass must be broken, and bars of iron cut asunder, ere the everlasting doors be opened for the King of glory to come in. The way of sin and Satan is a crooked way; to prepare a way for Christ, the paths must be made straight, Heb. xii. The garb in which he appeared, the figure he made, and the manner of his life,

This is he that was spoken of in the beginning of that part of the prophecy of Esaias, which is mostly evangelical, and which points at gospel-times and gospel-grace; see Isa. xl.

The prophet Esaias - The prophet Isaiah. Esaias is the Greek mode of writing the name. This passage is taken from Isa 40:3. It is here said to have been spoken in reference to John, the forerunner of Christ. The language is such as was familiar to the Jews. and such as they would understand. It was spoken at first with reference to the return from the captivity at Babylon.

These verses describe the ministry of John the Baptist, the forerunner of our Lord Jesus Christ: it is a ministry that deserves close attention. Few preachers ever produced such effects as John the Baptist: “There went out to him Jerusalem and all Judea and all the region round about Jordan.”None ever received such praise from the great head of the church: Jesus called him “a burning and a shining light” ( John 5:35 ); the great Bishop of souls Himself declared, that “among them that are born of women there hath not risen a greater than John the Baptist.”

The voice of one crying in the wilderness--(See on Lu 3:2); the scene of his ministry corresponding to its rough nature. Prepare ye the way of the Lord, make his paths straight--This prediction is quoted in all the four Gospels, showing that it was regarded as a great outstanding one, and the predicted forerunner as the connecting link between the old and the new economies.

These verses describe the ministry of John the Baptist, the forerunner of our Lord Jesus Christ: it is a ministry that deserves close attention. Few preachers ever produced such effects as John the Baptist: “There went out to him Jerusalem and all Judea and all the region round about Jordan.”None ever received such praise from the great head of the church: Jesus called him “a burning and a shining light” ( John 5:35 ); the great Bishop of souls Himself declared, that “among them that are born of women there hath not risen a greater than John the Baptist.” Let us then study the leading features of his ministry. John the Baptist spoke plainly about sin . He taught the absolute necessity of repentance before anyone can be saved; he preached that repentance must be proved by its “fruits”he warned men not to rest on outward privileges, or outward union with the church. This is just the teaching that we all need. We are naturally dead, and blind, and asleep in spiritual things; we are ready to content ourselves with a mere formal religion and to flatter ourselves that if we go to church we shall be saved: we need to be told that, except we “repent and are converted” we shall all perish. John the Baptist spoke plainly about our Lord Jesus Christ . He taught people that one “mightier than himself” was coming among them. He was nothing more than a servant: the coming one was the King. He himself could only baptize with water: the coming one could “baptize with the Holy Ghost,” take away sins, and would one day judge the world. This again is the very teaching that human nature requires. We need to be sent direct to Christ: we are all ready to stop short of this; we want to rest in our union with the church, our regular use of the sacraments, and our diligent attendance on an established ministry. We need to be told the absolute necessity of union with Christ himself by faith.

The voice of one crying in the wilderness - Or, A voice of a crier in the wilderness. This is quoted from Isa 40:3, which clearly proves that John the Baptist was the person of whom the prophet spoke. The idea is taken from the practice of eastern monarchs, who, whenever they entered upon an expedition, or took a journey through a desert country, sent harbingers before them, to prepare all things for their passage; and pioneers to open the passes, to level the ways, and to remove all impediments. The officers appointed to superintend such preparations were called by the Latins, stratores. Diodorus’s account of the march of Semiramis into Media and Persia, will give us a clear notion of the preparation of the way for a royal expedition. “In her march to Ecbatane, she came to the Zarcean mountain, which, extending many furlongs, and being full of craggy precipices and deep hollows, could not be passed without making a great compass about. Being therefore desirous of leaving an everlasting memorial of herself, as well as shortening the way, she ordered the precipices to be digged down, and the hollows to be filled up; and, at a great expense, she made a shorter and more expeditious road, which, to this day, is called from her, The road of Semiramis. Afterwards she went into Persia, and all the other countries of Asia, subject to her dominion; and, wherever she went, she ordered the mountains and precipices to be leveled, raised causeways in the plain country, and, at a great expense, made the ways passable.” Diod. Sic. lib. ii. and Bp. Lowth. The Jewish Church was that desert country, to which John was sent, to announce the coming of the Messiah. It was destitute at that time of all religious cultivation, and of the spirit and practice of piety; and John was sent to prepare the way of the Lord, by preaching the doctrine of repentance. […]
