Of course Jesus wasn't a Christian technically since he was/is the Christ. Do we see any signs that he was instituting a new religion called Christianity though? Let's check out some common "church" beliefs and see if Jesus ministry aligned with them.
Did Jesus demand that his followers adhere to a set of beliefs about his birth narrative in order to follow or know him? No. The gospel of Mark which is considered the oldest gospel doesn't even mention it.
Did Jesus require that his disciples believe in hell? No, the Old Testament scriptures never spoke of hell, and Jesus only warned his generation of "hell" on earth... Gehenna, the valley of Hinnom where hundreds of thousands of bodies would be cast and eaten by worms after the fall of Jerusalem in AD 70. Here are numerous articles demonstrating Jesus never taught on HELL.
Ageless Truth: Is This The End of the World?
Romans 11:36 –
All things came from Him, and exist through Him, and are returning to
Him; to Him is the glory through all the Ages.
When I was quite a new Christian (in my late teens and early 20’s) I noticed something which seemed to come up quite often, when the preacher or other people in a small group were using a different translation of the Bible than I was - it was one word. Just one word which was different - but it got me curious, and over and over again over the next couple of decades it seemed to come up ore and more. So eventually, I decided to investigate it. I have been reading about it and studying it seriously, on and off, for about 15 years now.
