From Catholic.org, Matthew 16:
22 Then, taking him aside, Peter started to rebuke him. ‘Heaven preserve you, Lord,’ he said, ‘this must not happen to you.’
23 But he turned and said to Peter, ‘Get behind me, Satan! You are an obstacle in my path, because you are thinking not as God thinks but as human beings do.’

I guess Peter’s demand didn’t bind Jesus in Heaven from not being crucified. It also appears that Jesus said that Peter was Satan.
This is your first Pope? Really?
I find those comments rather typical of a certain types of faith communities where people are not taught to love, respect, and venerate either the Jewish patriarchs or the Jewish apostles. Catholics love, respect, and. venerate them, including the blessed Apostle Peter, given the keys to the kingdom of heaven by the Messiah.
