That is interesting. It does seem apparent that Paul wasn't aware of the gospels. One would figure with the time frames that they would be written around the same time but independent of each other. I have not seen any indication the gospels were based off of Pauls writings even if they came after.Precisely. That's what a lot of people think, which is historically impossible.
Paul came first. Then the Gospels.
That's not to say that Paul did not know of some Jesus traditions, but his writings were in the churches and circulated before the Gospels. But it's not like Paul knew of the Gospels and radicalized them. It had to be the other way around.
