Peter was buried in Jerusalem.

If Peter was a Catholic why did he call himself a christian?

Also we dont read other book and add them to scripture. Rev: 22:18-19

Peter isnt the Rock Jesus is the Rock.

“In 1953, two Franciscan monks discovered hundreds of 1st century ossuaries stored in a cave on the Mount of Olives near Jerusalem. The archaeologists claimed to have discovered the earliest physical evidence of a Christian community in Jerusalem, including some very familiar Biblical names. The name inscribed on one ossuary read: "Shimon Bar Yonah" - Simon, the Son of Jonah, the original Biblical name of the Disciple Peter. However, several scholars, both Protestant and Catholic, disputed that the tomb belonged to Peter, one of the reasons being that there was no inscription referring to him as "Cefa" or "Peter".
