Jesus changed Peter's name elsewhere, not in Matthew 16.
John 1:42 And he brought him to Jesus. And when Jesus beheld him, he said, Thou art Simon the son of Jona: thou shalt be called Cephas, which is by interpretation, A stone. So why is it you are claiming it was changed in Matthew 16 if I can ask. Because this seems rather problematic. Who taught you that?

Matthew 16:

15 Jesus saith to them: But whom do you say that I am?

16 Simon Peter answered and said: Thou art Christ, the Son of the living God.

17 And Jesus answering said to him: Blessed art thou, Simon Bar-Jona: because flesh and blood hath not revealed it to thee, but my Father who is in heaven.

18 And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.

19 And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose on earth, it shall be loosed also in heaven.

I didn't claim that it came from Matthew 16. I just said that it was there somewhere and I don't have access to a bible at present.
