First Reading 1 PETER 5:1-4
1So I exhort the elders among you, as a fellow elder and a witness of the sufferings of Christ as well as a partaker in the glory that is to be revealed. 2Tend the flock of God that is your charge, not by constraint but willingly, not for shameful gain but eagerly, 3not as domineering over those in your charge but being examples to the flock. 4And when the chief Shepherd is manifested you will obtain the unfading crown of glory.
Responsorial Psalm PSALMS 23:1-6
1The LORD is my shepherd, I shall not want; 2he makes me lie down in green pastures. He leads me beside still waters; 3he restores my soul. He leads me in paths of righteousness for his name’s sake. 4Even though I walk through the valley of the shadow of death, I fear no evil; for thou art with me; thy rod and thy staff, they comfort me. 5Thou preparest a table before me in the presence of my enemies; thou anointest my head with oil, my cup overflows. 6Surely goodness and mercy shall follow me all the days of my life; and I shall dwell in the house of the LORD for ever.
Gospel MATTHEW 16:13-19
13Now when Jesus came into the district of Caesare’a Philip’pi, he asked his disciples, “Who do men say that the Son of man is?” 14And they said, “Some say John the Baptist, others say Eli’jah, and others Jeremiah or one of the prophets.” 15He said to them, “But who do you say that I am?” 16Simon Peter replied, “You are the Christ, the Son of the living God.” 17And Jesus answered him, “Blessed are you, Simon Bar-Jona! For flesh and blood has not revealed this to you, but my Father who is in heaven. 18And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it. 19I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.”
