Nobody is forcing you to believe it, but to continue to deny it sure cuts into your credibility.
You are giving St. Paul too much credit. CCC 105 God is the author of Sacred Scripture. "The divinely revealed realities, which are contained and presented in the text of Sacred Scripture, have been written down under the inspiration of the Holy Spirit."
"For Holy Mother Church, relying on the faith of the apostolic age, accepts as sacred and canonical the books of the Old and the New Testaments, whole and entire, with all their parts, on the grounds that, written under the inspiration of the Holy Spirit, they have God as their author, and have been handed on as such to the Church herself.
I have no argument with either God or Paul. I have an argument with those who would elevate the words of a bishop of the Church above the words of God. Anyone who follows Paul to the exclusion of Jesus Christ is not Christian. It is exemplified in various heresies identified during the first millennium after Christ.

Let's look at whose credibility is in question. Anyone who produces prose to the effect that disagreement with them equals disagreement with God has effectively lost the argument.
