They asked him, "Why then do you baptize, if you are not the Christ, nor Elijah, nor the Prophet?"
      (1.) Negatively. He was not that great one whom some took him to be. God's faithful witnesses stand more upon their guard against undue respect than against unjust contempt. Paul writes as warmly against those that overvalued him, and said, I am of Paul, as against those that undervalued him, and said that his bodily presence was weak; and he rent his clothes when he was called a god. [1.] John disowns himself to be the Christ (John 1:20; John 1:20): He said, I am not the Christ, who was now expected and waited for. Note, The ministers of Christ must remember that they are not Christ, and therefore must not usurp his powers and prerogatives, nor assume the praises due to him only. They are not Christ, and therefore must not lord it over God's heritage, nor pretend to a dominion over the faith of Christians. They cannot created grace and peace; they cannot enlighten, convert, quicken, comfort; for they are not Christ. Observe how emphatically this is here expressed concerning John: He confessed, and denied not, but confessed; it denotes his vehemence and constancy in making this protestation. Note, Temptations to pride, and assuming that honour to ourselves which does not belong to us, ought to be resisted with a great deal of vigour and earnestness. When John was taken to be the Messiah, he did not connive at it with a Si populus vult decipi, decipiatur--If the people will be deceived, let them; but openly and solemnly, without any ambiguities, confessed, I am not the Christ; hoti ouk eimi ego ho Christos--I am not the Christ, not I; another is at hand, who is he, but I am not. His disowning himself to be the Christ is called his confessing and not denying Christ. Note, Those that humble and abase themselves thereby confess Christ, and give honour to him; but those that will not deny themselves do in effect deny Christ, [2.] He disowns himself to be Elias, John 1:21; John 1:21. The Jews expected the person of Elias to return from heaven, and to live among them, and promised themselves great things from it. Hearing of John's character, doctrine, and baptism, and observing that he appeared as one dropped from heaven, in the same part of the country from which Elijah was carried to heaven, it is no wonder that they were ready to take him for this Elijah; but he disowned this honour too. He was indeed prophesied of under the name of Elijah (Malachi 4:5), and he came in the spirit and power of Elias (Luke 1:17), and was the Elias that was to come (Matthew 11:14); but he was not the person of Elias, not that Elias that went to heaven in the fiery chariot, as he was that met Christ in his transfiguration. He was the Elias that God had promised, not the Elias that they foolishly dreamed of. Elias did come, and they knew him not (Matthew 17:12); nor did he make himself known to them as the Elias, because they had promised themselves such an Elias as God never promised them. [3.] He disowns himself to be that prophet, or the prophet. First, He was not that prophet which Moses said the Lord would raise up to them of their brethren, like unto him. If they meant this, they needed not ask that question, for that prophet was no other than the Messiah, and he had said already, I am not the Christ. Secondly, He was not such a prophet as they expected and wished for, who, like Samuel and Elijah, and some other of the prophets, would interpose in public affairs, and rescue them from under the Roman yoke. Thirdly, He was not one of the old prophets raised from the dead, as they expected one to come before Elias, as Elias before the Messiah. Fourthly, Though John was a prophet, yea, more than a prophet, yet he had his revelation, not by dreams and visions, as the Old-Testament prophets had theirs; his commission and work were of another nature, and belonged to another dispensation. If John had said that he was Elias, and was a prophet, he might have made his words good; but ministers must, upon all occasions, express themselves with the utmost caution, both that they may not confirm people in any mistakes, and particularly that they may not give occasion to any to think of them above what is meet.
