[Old Yeller]

Jesus didn’t found the Catholic Church.

Yes, He did. It's probably even in your Bible.

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. Matthew 16:18

Upon this rock

[ebb tide]

I read your link. It didn’t mention that Peter was formerly named Simon, until Christ renamed him. I wonder if that omission was intentional.
