Matthew 16:16

Art - "Are"; second person singular.

Thou art the Christ, the Son of the living God - Every word here is emphatic - a most concise, and yet comprehensive, confession of faith.

The Christ, or Messiah, points out his divinity, and shows his office; the Son - designates his person: on this account it is that both are joined together so frequently in the new covenant. Of the living God Του Θεου, του ζωντος, literally, of God the Living One. The C. Bezae has for Του ζωντος the Living One, Του σωζοντος, the Savior, and the Cant. Dei Salvatoris, of God the Savior.

Living - a character applied to the Supreme Being, not only to distinguish him from the dead idols of paganism, but also to point him out as the source of life, present, spiritual, and eternal. Probably there is an allusion here to the great name יהוה Yeve, or Yehovah, which properly signifies being or existence.

And Simon Peter answered ... - Peter, expressing the views of the apostles, with characteristic forwardness answered the question proposed to them by Jesus: "Thou art the Christ, the Son of the living God."

The Christ - The Messiah, the "Anointed" of God. See the notes at Matthew 1:1.

The Son - That is, the Son by way of eminence - in a special sense. See the notes at Matthew 1:17. This appellation was understood as implying divinity, John 10:29-36.

Of the living God - The term "living" was given to the true God to distinguish him from idols, that are dead, or lifeless blocks and stones. He is also the Source of life, temporal, spiritual, and eternal. The word "living" is often given to him in the Old Testament, Joshua 3:10; 1 Samuel 17:26, 1 Samuel 17:36; Jeremiah 10:9-10, etc. In this noble confession Peter expressed the full belief of himself and of his brethren that he was the long-expected Messiah. Other people had very different opinions of him, but they were satisfied, and were not ashamed to confess it.

16:16 Peter - Who was generally the most forward to speak.
