25. Why then dost thou baptize ? By laying down those three degrees, they appear to form a very conclusive argument : if thou art not the Christ, nor Elijah, nor a prophet; for it does not belong to every man to institute the practice of baptism. The Messiah was to be one who possessed all authority. Of Elijah who was to come, they had formed this opinion, that he would commence the restoration both of the royal authority and of the Church. The prophets of God, they readily grant, have a right to discharge the office committed to them. They conclude, therefore, that for John to baptize is an unlawful novelty, since he has received from God no public station. But they are wrong in not acknowledging him to be that Elijah who is mentioned by Malachi 4:5; though he denies that he is that Elijah of whom they foolishly dreamed.
