Matthew 16:16

And Simon Peter answered and said
Either of his own accord, and for himself, being a warm, zealous, and forward man; one that dearly loved Christ, truly believed in him, and was ready to make a confession of him; or, as the mouth of the rest, in their name, and with their consent; or, at least, as full well knowing the sentiments of their minds. Thou art Christ, the Son of the living God: a short, but a very full confession of faith, containing the following articles: as that there is a God, that there is but one God; that he is the living God, has life in himself, is the fountain of life to others, and by this is distinguishable from the idols of the Gentiles: that Jesus is the Christ, the Christ of God, the true Messiah, that was promised by God, prophesied of by all the prophets, from the beginning of the world, and expected by the people of God: a character that includes all his offices, of prophet, priest, and king, to which he is anointed by God; and that this Messiah was not a mere man, but a divine person, the Son of God; not by creation, as angels and men are, nor by adoption, as saints, nor by office, as magistrates, but by nature, being his own Son, his proper Son, the only begotten of the Father, of the same nature with him, being one with him, and equal to him. This confession, as it is uniform, and all of a piece, and consistent with itself, and is what all the disciples of Christ agreed in, so it greatly exceeds the most that can be made of the different sentiments of the people put together. They took him, one and all, to be but a mere man; their most exalted thoughts of him rose no higher: but in this he is acknowledged to be the Son of God, a phrase expressive of his divine nature, and distinct personality: they thought him to be a dead man brought to life; but here he is called the Son of the living God, as having the same life in him the Father has: they indeed judged him to be a prophet, but not that prophet that was to come, superior to all prophets; but here he is owned to be the Christ, which not only takes in his prophetic office in a higher sense than they understood it, but all his other offices, and declares him to be the promised Messiah; which they who thought, and spoke the most honourably of him, could not allow of.
