Whoever Paul might have actually been he was not an eye witness. He was developing his missives well after the supposed life time of Jesus. So once again it is stuff which is not contemporaneous, first hand or verifiable nor to be frank, the product of a mentally well balanced person unless it was written as fiction. Anyone who reads Paul while maintaining a grain of common sense would immediately see why. If you say Paul invented Christians and or Christianity, then you do indeed confirm how Jesus is the product of Paul's Christianity not the source. And of course it goes without saying that because the person calling himself Paul says something in the Bible, it doesn't mean that what Paul says in the Bible is true or real, any more than what C.S.Lewis says in The Chronicles of Narnia is true or real. The Jesus character was the Messiah, first crafted by the writings of messianic Jewish sects separating themselves from Judaism before Paul came along. So it could be said they were Christians before Christ was later re-invented by Christians. if anyone holds the copyright on Jesus, it must be the early dissenting Jews. The term Christian was not first used by Paul but was used in mockery, not to denote divinity. The rest, as they say, is show business and the Bible, being much the same things.
