The Confession of Peter is a statement made by Saint Peter the Apostle in the Synoptic Gospels of Matthew 16:13–20, Mark 8:27–30, and Luke 9:18–20, in which he emphatically acknowledged Jesus as the "Messiah" or "Christ" (meaning the Anointed One).
The Confession of Peter is also the name of a liturgical feastday celebrated by some Christian churches. The feast also marks the beginning of the Octave for Church Unity.
Propers for the Confession of Peter - 18 January
Almighty Father, who inspired Simon Peter, first among the apostles, to confess Jesus as Messiah and Son of the living God: Keep Thy Church steadfast upon the rock of this faith, so that in unity and peace we may proclaim the one truth and follow the one Lord, our Savior Jesus Christ; who liveth and reigneth with Thee and the Holy Ghost, one God, now and for ever. Amen.
The Epistle - Acts 4: 8-13.
Then Peter, filled with the Holy Ghost, said unto them, Ye rulers of the people, and elders of Israel, If we this day be examined of the good deed done to the impotent man, by what means he is made whole; Be it known unto you all, and to all the people of Israel, that by the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even by him doth this man stand here before you whole. This is the stone which was set at nought of you builders, which is become the head of the corner. Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. Now when they saw the boldness of Peter and John, and perceived that they were unlearned and ignorant men, they marvelled; and they took knowledge of them, that they had been with Jesus.
The Gospel - St. Matthew 16:13-19.
When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am? And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets. He saith unto them, But whom say ye that I am? And Simon Peter answered and said, Thou art the Christ, the Son of the living God. And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven. And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.
