We don't consider the Epistles canon - they are from the old Catholic church.
Well, I don't know who "we" is, but if you're rejecting any Scripture then we have absolutely nothing to discuss. And, by the way, there are many Catholics on this forum who reject anything written by Paul, so why you discard this particular Scripture because it was part of the Catholic church is a mystery.
I have yet to find any authorization given by God to man for man to pick and choose which Scripture is true and which is false. I have to tell you that the fact that you apparently feel that you have the omniscience to throw out any part of God's word puts you in a pretty dangerous position.
At any rate, the Scripture clearly states that salvation comes through the faith given by the grace of God. Repentance is something that comes after a person has received the gift of faith. And there is no Scripture you can find that will contradict that.
