The rock Christ was speaking of was Peters confession of Jesus as Christ not Peter himself Just a few verses later Jesus calls Peter Satan If you want your church based on Peter go ahead Mine is based on the only true foundation Jesus Christ And the gates of hell have been smashed by that same Jesus
There you go interpreting the Bible for yourself and doing it badly. Lol.
This errant interpretation has been rightly rejected by all notable theologians, scholars, saints and martyrs, and was so for the first 1400 years before we saw the plague of Protestantism flood this earth with a mudslide of heresies from Joel Osteen and Billy Graham to David Koresh and Jim Jones, and right down to your current crop of televangelists.
Try explaining this to the vast constellation of people who have converted to Catholicism. These folks are not your run-of-the-mill fools.

Great! But again your wrong.
Do you have some scalpel you can use to carve Peter's confession away from Peter himself? That would take a sharp blade.
Oh, and John 21:15-19.
