In the New Testament – in the Gospels of Mark, Matthew, and Luke – very similar wording is used to tell the same stories in the same sequence, so these are thought of as the 'synoptic' Gospels.
At one point in each of those narratives, (Mark Chapter 8, verse 27, and in Matthew Chapter 16, verses 13-20, and also in Luke Chapter 9, verses 18–20),
"Who do the multitudes say that I am?"
In response, the disciples provide a wide range of answers. Jesus then asks:
“Who do you say that I am?
The only reply comes from Simon:
“You are the Christ, the Son of the living God.”
In Matthew, Chapter 16, verse 17, Jesus blesses Simon and designates him now as Peter, the rock, and says that upon this rock he will build his church, and lets him and the other disciples know that he is to give Peter "the keys of the kingdom of heaven." In doing so, he acknowledges that he is the Christ, and the son of Almighty God.
The Roman Catholic Church traces its heritage back to the apostle Peter, as the first Vicar of Christ on earth -- and the first Pope.
In the following Chapter of Matthew, in verse 1–9 (and in Mark Chapter 9, verses 2–8; and in Luke Chapter 9, verses 28–36) radiant, on a mountaintop, Jesus is transfigured, with bright rays of light emanating from him, and as the Old Testament prophets Moses and Elijah appear with him, a voice assumed to be God the Father is heard to refer to him as his son – marking the nature of the incarnation of Jesus in his human incarnation and as Jesus the son of God.
The Gospel according to Matthew:
"Now Jesus stood before the governor; and the governor asked him,
"Are you the King of the Jews?"
"You have said so."
But when he was accused by the chief priests and elders, he made no answer.
Then Pilate said to him,
"Do you not hear how many things they testify against you?"
But he gave him no answer, not even to a single charge; so that the governor wondered greatly.
Now at the feast the governor was accustomed to release for the crowd any one prisoner whom they wanted. And they had then a notorious prisoner, called Barab'bas.
So when they had gathered, Pilate said to them,
"Whom do you want me to release for you, Barab'bas or Jesus who is called Christ?"
For he knew that it was out of envy that they had delivered him up.
Besides, while he was sitting on the judgment seat, his wife sent word to him,
"Have nothing to do with that righteous man, for I have suffered much over him today in a dream."
Now the chief priests and the elders persuaded the people to ask for Barab'bas and destroy Jesus. The governor again said to them,
"Which of the two do you want me to release for you?"
And they said,
Pilate said to them,
"Then what shall I do with Jesus who is called Christ?"
They all said,
"Let him be crucified."
And he said,
"Why, what evil has he done?"
But they shouted all the more,
"Let him be crucified."
So when Pilate saw that he was gaining nothing, but rather that a riot was beginning, he took water and washed his hands before the crowd, saying,
"I am innocent of this man's blood; see to it yourselves."
