But we must observe, that Peter most wisely confessed Christ to be one, against those who presumed to divide Immanuel into two Christs. For Christ did not enquire of them, saying, Whom do men say the divine Word is? but the Son of man, whom Peter confessed to be the Son of God. Herein then is Peter to be admired, and thought worthy of such chief honour, seeing that Him whom he marvelled at in our form, he believed to be the Christ of the Father, that is to say, that the Word which proceeded of the Father’s Substance was become man.
