Jesus was referring to false prophets when He gave that warning. I don't think I've ever heard anyone allude to Paul as a false prophet, esp after how God brought him into the faith. He was in fact the greatest apostle that lived, taught and wrote for our benefit. You might want to read the last words in Revelation and the Bible how we are instructed not to add to or take away from the word of God. You are on very dangerous ground.
You can believe what you wish. I choose to believe in Jesus. His teachings on salvation are sufficient for me. Are they not for you?
As to the warning in Revelation. That concerned the writings in the book of Revelation. The New Testament had not been put together at that time. So by your reasoning the New Testament was an addition to the word of God. Is it not?
Patriotism (and religion) is the last refuge of a scoundrel.
