Being human, as I assume you are, it is possible for you to believe a falsehood, yes?
Let's see. I took Paul at his literal word according to the Gospel of the grace of God. That's what I believed, and believe.
If I have believed a falsehood, then that Gospel is a lie.
If that's the case, you must throw the Bible in the trash, go atheist and never look back.
If Paul's Gospel is a lie, then Paul lied.
Repeatedly. His letters are therefore untrustworthy and can rightly be trashed.
If Paul goes, then Luke goes with him for falsely or mistakenly attesting to Paul's apostleship. That means Luke can't be trusted and his gospel account and the book of Acts are trashed as well.
If Paul goes, then Peer goes as well. He also attested to Paul's apostleship in 2 Peter 3. That means Peter - your falsely purported first pope - can't be trusted either. He's out.
For your to be correct in what we both KNOW you believe (that Paul's Gospel is a lie), you have to gut the NT by about half and destroy the rest along with it.
Turn in your scapular, you don't need it anymore. Dawkins' fan club is still accepting new members.
