No, he was not the first or second or even the third Pope. You guys got that all wrong.
The unbroken testimony of two thousand years declares Peter the first pope.
The notion that he was not the first pope was invented out of whole cloth by anti-papal obsessives 1500 years later.
Actually, you're right. What he was was the Apostle that ordained the first pope. But he was also Christ's steward on earth, as are his successors.
Plenty of evidence out there, dearie. Read "Upon This Rock" by Stephen K. Ray. "Jesus, Peter and the Keys" by Scott Butler is pretty good, too.
