EPISTLE 1 Peter 5: 1-4, 10-11
Lesson from the First Book of Peter. Dearly beloved, the ancients therefore that are among you, I beseech , who am myself also am ancient, and a witness of the sufferings of Christ : as also a partaker of that glory which is to be revealed in time to come: feed the flock of God which is among you, taking care of it, not by constraint, but willingly, according to God: not for filthy lucre’s sake, but voluntarily: neither as lording it over the clergy, but being made a pattern of the flock from the heart. And when the prince of pastors shall appear, you shall receive a never fading crown of glory. But the God of all grace, Who hath called us unto His eternal glory in Christ Jesus, after you have suffered a little, will himself perfect you, and confirm you, and establish you. To Him be glory and empire for ever and ever. Amen.

GOSPEL Matthew 16: 13-19
At that time, Jesus came into the quarters of Cæsarea Philippi, and He asked His disciples, saying, “Whom do men say that the Son of man is?” But they said, Some, John the Baptist, and other some, Elias, and others, Jeremias, or one of the prophets. Jesus saith to them, “But whom do you say that I am?” Simon Peter answered, Thou art Christ, the Son of the living God. And Jesus answering, said to him, “Blessed art thou, Simon Bar-Jona, because flesh and blood hath not revealed it to thee, but My Father Who is in Heaven: and I say to 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 to thee I will give the keys of the kingdom of Heaven; and whatsoever thou shalt bind upon earth, it shall be bound also in Heaven; and whatsoever thou shall loose on earth, it shall be loosed also in Heaven.”
