It’s because your evangelical co-worker doesn’t know his bible. Peter is mentioned 155 times, and the other Apostles are mentioned 130 times **combined. **This is from Matthew right through to Revelation.
Ask your co-worker why Peter is always mentioned first with only two exceptions. (1 Cor. 3:22 and Gal. 2:9)
Ask your co-worker if Paul walked on water, if Paul was the first to confess Christ’s divinity, if Paul or anybody else received the keys, if Jesus preached from Paul’s boat, etc., etc.

Gal. 2:11-14 - non-Catholics sometimes use this verse to diminish Peter’s evident authority over the Church. This is misguided. In this verse, Paul does not oppose Peter’s teaching, but his failure to live by it. Infallibility (teaching without error) does not mean impeccability (living without sinning). Peter was the one who taught infallibly on the Gentile’s salvation in Acts 10,11.
With this rebuke, Paul is really saying “Peter, you are our leader, you teach infallibly, and yet your conduct is inconsistent with these facts. You of all people!” The verse really underscores, and not diminishes the importance of Peter’s leadership in the Church.
I would add that no Pope makes definitive declarations while hiding in fear, (verse 12), so Peter is not teaching at all by such hiding.
If shear volume of writing constitues authority, St. Thomas Aquinas or St. Augustine would have been Popes.:whacky:
