Saint Matthew 16:13-20.
Book of Isaiah 22:19-23.
I will thrust you from your office and pull you down from your station. On that day I will summon my servant Eliakim, son of Hilkiah; I will clothe him with your robe, and gird him with your sash, and give over to him your authority. He shall be a father to the inhabitants of Jerusalem, and to the house of Judah. I will place the key of the House of David on his shoulder; when he opens, no one shall shut, when he shuts, no one shall open. I will fix him like a peg in a sure spot, to be a place of honor for his family;
Of David. I thank you, LORD, with all my heart; before the gods to you I sing. I bow low toward your holy temple; I praise your name for your fidelity and love. For you have exalted over all your name and your promise. I bow low toward your holy temple; I praise your name for your fidelity and love. For you have exalted over all your name and your promise. I bow low toward your holy temple; I praise your name for your fidelity and love. For you have exalted over all your name and your promise. When I cried out, you answered; you strengthened my spirit. The LORD is on high, but cares for the lowly and knows the proud from afar. The LORD is with me to the end. LORD, your love endures forever. Never forsake the work of your hands! The LORD is with me to the end. LORD, your love endures forever. Never forsake the work of your hands!
Letter to the Romans 11:33-36.
Oh, the depth of the riches and wisdom and knowledge of God! How inscrutable are his judgments and how unsearchable his ways! "For who has known the mind of the Lord or who has been his counselor?" "Or who has given him anything that he may be repaid?"
For from him and through him and for him are all things. To him be glory forever. Amen.
Holy Gospel of Jesus Christ according to Saint Matthew 16:13-20.
When Jesus went into the region of Caesarea Philippi he asked his disciples, «Who do people say that the Son of Man is?» They replied, "Some say John the Baptist, others Elijah, still others Jeremiah or one of the prophets." He said to them, "But who do you say that I am?" Simon Peter said in reply, "You are the Messiah, the Son of the living God." Jesus said to him in reply, "Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my heavenly Father. And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it. I will give you the keys to the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven." Then he strictly ordered his disciples to tell no one that he was the Messiah.

"Upon this rock I will build my Church"
The Lord directly questioned the Twelve: "But who do you say that I am?". Peter spoke enthusiastically and authoritatively on behalf of them all: "You are the Christ, the Son of the living God". This solemn profession of faith the Church continues to repeat since then. Today too, we long to proclaim with an innermost conviction: "Yes, Jesus, you are the Christ, the Son of the living God!". Let us do so in the awareness that Christ is the true "treasure" (Mt 13,44) for whom it is worth sacrificing everything; he is the friend who never abandons us for he knows the most intimate expectations of our hearts. Jesus is the "Son of the living God", the promised Messiah who came down to earth to offer humanity salvation and to satisfy the thirst for life and love that dwells in every human being. What an advantage humanity would have in welcoming this proclamation which brings with it joy and peace! "You are the Christ, the Son of the living God". Jesus answers Peter's inspired profession of faith: "You are Peter, and on this rock I will build my Church, and the powers of death shall not prevail against it. I will give you the keys of the Kingdom of Heaven". This is the first time that Jesus speaks of the Church, whose mission is the actuation of God's great design to gather the whole of humanity into a single family in Christ. Peter's mission, and that of his Successors, is precisely to serve this unity of the one Church of God formed of Jews and pagans of all peoples; his indispensable ministry is to ensure that she is never identified with a single nation, with a single culture, but is the Church of all peoples - to make present among men and women, scarred by innumerable divisions and conflicts, God's peace and the renewing power of his love. This, then, is the special mission of the Pope, Bishop of Rome and Successor of Peter: to serve the inner unity that comes from God's peace, the unity of those who have become brothers and sisters in Jesus Christ.
