Fundamento bíblico de que a Igreja foi constituída sobre a autoridade de Pedro e o Poder das Chaves dado a ele

16 In answer Simon Peter said, ‘You are the Messiah, the Son of the living God.’
17 In reply Jesus said to him, ‘Blessed are you, Simon son of Jonah, for flesh and blood has not revealed this to you but my Father in heaven.
18 So I now say to you: “You are Peter and on this rock I will build my church. And the gates of the underworld will never overpower it.
19 I will give you the keys of the kingdom of Heaven: whatever you bind on earth will be bound in heaven;d whatever you loose on earth will be loosed in heaven.” ’
