Muslims, by contrast, venerate the Messiah—peace be upon him—and follow him in truth far more than those Christians who altered his religion and opposed him. They affirm everything he said about himself; they do not twist his words from their proper context, nor do they interpret his speech—or the speech of any other prophet—in a sense he never intended, as the Christians have done. They report that the Messiah said, “Baptize the people in the name of the Father, the Son, and the Holy Spirit.” If the Messiah did in fact utter these words, they must be understood according to his own language, his customary style of address, and the conventions shared by the other prophets.
