The EO do with these verses what the Protestants do with “this is my body”, but here are the verses:
Matthew 16:18-19
And 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.** I 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.
The “keys” of authority that Jesus gives to Peter is even acknowledged in Heaven.
Luke 22:32
but I [Jesus] have prayed for you [Peter] that your faith may not fail; and when you have turned again, strengthen your brethren.
John 21:17
He [Jesus] said to him the third time, “Simon, son of John, do you love me?” Peter was grieved because he said to him the third time, “Do you love me?” And he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep."
Are we not Jesus’ sheep?
