John 6
 Therefore the Jews were grumbling about Him, because He said, “I am the bread that came down out of heaven.” They were saying, “Is not this Jesus, the son of Joseph, whose father and mother we know? How does He now say, ‘I have come down out of heaven’?” Jesus answered and said to them, “Do not grumble among yourselves. No one can come to Me unless the Father who sent Me draws him; and I will raise him up on the last day. It is written in the prophets, ‘And they shall all be taught of God.’ Everyone who has heard and learned from the Father, comes to Me. Not that anyone has seen the Father, except the One who is from God; He has seen the Father. Truly, truly, I say to you, he who believes has eternal life. I am the bread of life. Your fathers ate the manna in the wilderness, and they died. This is the bread which comes down out of heaven, so that one may eat of it and not die. I am the living bread that came down out of heaven; if anyone eats of this bread, he will live forever; and the bread also which I will give for the life of the world is My flesh.”
 Then the Jews began to argue with one another, saying, “How can this man give us His flesh to eat?” So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves. He who eats My flesh and drinks My blood has eternal life, and I will raise him up on the last day. For My flesh is true food, and My blood is true drink. He who eats My flesh and drinks My blood abides in Me, and I in him. As the living Father sent Me, and I live because of the Father, so he who eats Me, he also will live because of Me. This is the bread which came down out of heaven; not as the fathers ate and died; he who eats this bread will live forever.”
Words to the Disciples

Mat 16:13 ¶ Now when Jesus came into the district of Caesarea Philippi, He was asking His disciples, “Who do people say that the Son of Man is?”
14 And they said, “Some say John the Baptist; and others, Elijah; but still others, Jeremiah, or one of the prophets.”
15 He *said to them, “But who do you say that I am?”
16 Simon Peter answered, “You are the Christ, the Son of the living God.”
17 And Jesus said to him, “Blessed are you, Simon Barjona, because flesh and blood did not reveal this to you, but My Father who is in heaven.
18 “I also say to you that you are Peter, and upon this rock I will build My church; and the gates of Hades will not overpower it.
19 “I will give you the keys of the kingdom of heaven; and whatever you bind on earth shall have been bound in heaven, and whatever you loose on earth shall have been loosed in heaven.”
