Or if QI is to be believed Christianity was ripped off by the Romans to be the official state religion 200 years after Jesus' death using one of their existing religions as a template.
not quite, there is evidence of all sorts of denominations flying around during the first couple centuries AD. The romans DID steal the religion but with any faith back then (and still now) its formed through the filter of current beliefs. so the pagan birth and harvest festivals became easter and so on. Also with the official adoption of the religion for the state, the first council of Nicaea was called to bring all the cannon together. The romans pick and chose the best parts of the story for themselves. Thats is why the bible has only the 4 gospels in the new testament. All the other parts either were contradictory or said something unflattering about certain parts of society.
nope, its named after him but he was a jew until the end ('king of the jews' was hung round his neck on the cross) the catholic tradition and therefore the religion was started (traditionally) by the apostles after the death of jesus. specifically St Paul.
I always thought the Romans hung it around his neck as a joke, with the crown and stuff...
"Hey look at this Jesus guy, he calls himself Christian now.. Lets put a sign around his neck with "king of the jews" around his neck to piss him off"
Thanks for making me a good Christian, Lazzars...
the king of the jews thing was a bit of a jab at jesus but also all his people, the phrase "King of the Jews" had a lot of connotations back then, remember that though herod was the ruler of the kingdom of judah; they weren't the kings as the kingdom was destroyed by the romans a generation before (destruction of the first temple of soloman). so by killing their king the romans were trying to piss off the jews and show their dominion of their people (like there were again a slave race)
also the term "king of the jews" was used by the jewish people to refer to a prophetical messiah they were waiting for. To refer to one's self as the true messiah was blasphemous and likely to get you sent to hell. thats why in the story the jewish leaders wanted jesus dead.
TL:DR jesus made a good story
