O God, Who raised blessed Peter Celestine to the lofty dignity of Supreme~
Pontiff and taught him to prefer self-abasement instead; mercifully grant that~
by his example we may look upon all worldly things as naught, and may be worthy~
to reap in joy the rewards promised to the humble.

[Lectio]
Lesson from the first letter of St. Peter the Apostle
!1 Pet. 5:1-4; 5:10-11.
Beloved: I exhort the presbyters among you - I, your fellow presbyter and witness of the sufferings of Christ, the partaker also of the glory that is to be revealed in time to come - tend the flock of God which is among you, governing not under constraint, but willingly, according to God; nor yet for the sake of base gain, but eagerly; nor yet as lording it over your charges, but becoming from the heart a pattern to the flock. And when the Prince of the shepherds appears, you will receive the unfading crown of glory. But the God of all grace, Who has called us unto His eternal glory in Christ Jesus, will Himself, after we have suffered a little while, perfect, strengthen and establish us. To Him is the dominion forever and ever. Amen.

[Evangelium]
Continuation + of the Holy Gospel according to Matthew
!Matt 16:13-19
At that time, Jesus, having come into the district of Caesarea Philippi, began~
to ask His disciples, saying, Who do men say the Son of Man is? But they said,~
Some say, John the Baptist; and others, Elias; and others, Jeremias, or one of~
the prophets. He said to them, But who do you say that I am? Simon Peter~
answered and said, You are the Christ, the Son of the living God. Then Jesus~
answered and said, Blessed are you, Simon Bar-Jona, for flesh and blood has not~
revealed this to you, but My Father in heaven. And I say to you, you are Peter,~
and upon this rock I will build My Church, and the gates of hell shall not~
prevail against it. And I will give you the keys of the kingdom of heaven; and~
whatever you shall bind on earth shall be bound in heaven, and whatever you~
shall loose on earth shall be loosed in heaven.
