Aren't you the one who rejects the Protestant / Reformed understanding of baptism and the Lord's Supper? Don't you believe that only Paul's epistles are applicable to today, and that the Gospels are of no effect, being meant for the Jews?
There are many Protestants who believe that only Paul's Epistles have any merit or application to Christians. There are many who believe that only Luke and Acts are useful. Some throw in Isaiah. Most have a horror of Jude, and almost never refer to Matthew.
I’m the one who stands waiting patiently for someone from the RCC to give a sensible answer to the simple question: Why Paul? If Peter and the 11 were given the great commission from Christ, and understood plainly what they were to do (and they did), why does Paul claim in Rom. 11:13 that he is the Apostle to the Gentiles (and he was, as given to him by direct revelation from the risen Christ). It’s just a simple question that has yet to be answered.
