“Paul, who wrote most of the new testament never met Christ nor received any Gospel directly from him.”
He did, it was just post-resurrection.
“11-12 The Gospel I preach to you is no human invention. No man gave it to me, no man taught it to me; it came to me as a direct revelation from Jesus Christ.
13-19 For you have heard of my past career in the Jewish religion, how I persecuted the Church of God with fanatical zeal and, in fact, did my best to destroy it. I was ahead of most of my contemporaries in the Jewish religion, and had a greater enthusiasm for the old traditions. But when the time came for God (who had chosen me from the moment of my birth, and then called me by his grace) to reveal his Son within me so that I might proclaim him to the non-Jewish world, I did not, as might have been expected, talk over the matter with any human being. I did not even go to Jerusalem to meet those who were God’s messengers before me—no, I went away to Arabia and later came back to Damascus. It was not until three years later that I went up to Jerusalem to see Peter, and I only stayed with him just over a fortnight. I did not meet any of the other messengers, except James, the Lord’s brother.
20-24 All this that I am telling you is, I assure you before God, the plain truth. Later, I visited districts in Syria and Cilicia, but I was still personally unknown to the churches of Judea. All they knew of me, in fact, was the saying: “The man who used to persecute us is now preaching the faith he once tried to destroy.” And they thanked God for what had happened to me.”
Just because it took three years for Paul to reveal what had happened to him on the road to Damascus doesn't mean he spent three years living with Christ and learning from him.
I think if any such thing had happened we would have 100’s of quotes of what post resurrection Jesus said to him during those three years (while all we have are the quotes from what was said to him on the road to Damascus, which wasn't much).
But not a single direct quotation of anything Jesus personally said to Paul after the encounter on the road during that three year period is written in the bible.
Which brings me back to my original argument, what makes Paul's God inspired revelations any different or important than the millions of other people who have had revelations from God over the ensuing 2000 years?
