They asked him, "What then? Are you Elijah?" He said, "I am not." "Are you the Prophet?" He answered, "No."
      (1.) The enquiry which the committee made about it: Why baptizest thou, if thou be not the Christ, nor Elias, nor that prophet?John 1:25; John 1:25. [1.] They readily apprehended baptism to be fitly and properly used as a sacred rite or ceremony, for the Jewish church had used it with circumcision in the admission of proselytes, to signify the cleansing of them from the pollutions of their former state. That sign was made use of in the Christian church, that it might be the more passable. Christ did not affect novelty, nor should his ministers. [2.] They expected it would be used in the days of the Messiah, because it was promised that then there should be a fountain opened (Zechariah 13:1), and clean water sprinkled,Ezekiel 36:25. It is taken for granted that Christ, and Elias, and that prophet, would baptize, when they came to purify a polluted world. Divine justice drowned the old world in its filth, but divine grace has provided for the cleansing of this new world from its filth. [3.] They would therefore know by what authority John baptized. His denying himself to be Elias, or that prophet, subjected him to this further question, Why baptizest thou? Note, It is no new thing for a man's modesty to be turned against him, and improved to his prejudice; but it is better that men should take advantage of our low thoughts of ourselves, to trample upon us, than the devil take advantage of our high thoughts of ourselves, to tempt us to pride and draw us into his condemnation.
