那時候，耶穌來到了斐理伯的凱撒勒雅境內，就問門徒說： 「人們說人子是誰？」他們說：「有人說是洗者若翰；有人說是厄里亞；也有人說是耶肋米亞，或先知中的一位。」耶穌對他們說：「你們說我是誰？」西滿伯多祿回答說：「你是默西亞，永生天主之子。」耶穌回答他說：「約納的兒子西滿，你是有福的，因為不是肉和血啟示了你，而是我在天之父。我再給你說： 你是伯多祿（磐石）：在這磐石上，我要建立我的教會：陰間的門決不能戰勝她。我要將天國的鑰匙交給你：凡你在地上所束縛的，在天上也要被束縛；凡你在地上所釋放的，在天上也要被釋放。」

A Reading from the Holy Gospel according to Matthew 16:13-19
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 Christ, 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.”
