“Flesh and blood has not revealed this to you, but My Father who is in heaven,” the Lord said to Simon Peter (Mt 16:17). For among men “no one can say that Jesus is Lord except by the Holy Spirit” (1 Cor 12:3).
Peter appeared as the representative of the faith of the eleven faithful Apostles. Yet in his confession there is also his own individual warmth of feeling, a faith burning with love.
This was the reason why the Lord, knowing and foretelling Peter’s fall, said to him, “When you have returned, strengthen your brethren” (Lk 22:32).
Indeed, we see that Peter’s words burst from the depth of his heart in a warm stream. Almost with desperation he utters the touching words, “Lord, to whom shall we go?”
He fears that the Lord might suspect them of unfaithfulness and send them away from Himself. “You, Lord,” he says, “have the words of eternal life.”
Perhaps more than all the other disciples, Peter had detached himself from the earthly and cleaved to the heavenly. The words of life had filled his soul with unspeakable joy.
He sincerely says that, having tasted them, he can no longer live without them. This character of Peter’s ardent faith and love stands out especially in the Gospel of John, which nevertheless does not hide Peter’s denial (Jn 18:26-27).
Let us remember that John was the beloved disciple and an eyewitness of all the events of the Lord’s earthly life.
“We have believed,” says the chief Apostle on behalf of all twelve, not yet suspecting the betrayal being prepared by one of them. “We have known that You are the Christ, the Son of the living God.”
The expression of faith is literally the same as that recorded from Peter’s lips in the Evangelist Matthew, 16:16.
This confession of faith, formed in an unchanging form in the minds of the believing disciples, contains the dogma formulated by Peter’s lips.
It was written by the Evangelists Matthew and John at the command of the Holy Spirit for the guidance of all believers.
“You are the Christ.” That is, You are the One whom from ancient times we have awaited under the name of the Anointed One. Messiah and Christ are equivalent names, the Hebrew and the Greek, meaning Anointed.
Moses and the prophets foretold You. You brought in Yourself the expected deliverance.
“You are the Son of God.” You are the Son of the Living One, that is, of the eternally Existing One, Jehovah, the God of the Covenant. You are consubstantial with Him.
Thus, in the mouth of Peter, according to the will of the Spirit of God, the formula of the dogma is composed.
It binds the Old Covenant with the New, in fulfillment of the promise concerning the coming of the Savior, Reconciler, and Redeemer.
In His mouth are the words of life, while His Body is given up to the dread breaking as a sacrifice for the sin of men.
But the disciples do not yet know this. So far, they know only the words of life. They will understand all things afterward.
Yet only those will understand who have loved the words of life and confessed the Lord through the mouth of Peter.
