What happens if Jesus is born female? No Christianity I would guess.
Indeed. The main reason why Christianity spread vastly and became the Imperial Religion is thanks to Paul's work. Without his efforts Christ's teachings would've stayed put in the Middle East, or slowly eroded away.I really, really don't want to get into a theological argument, but historically speaking, the circumstances of Jesus' birth are questionable at best. Jesus was one of many self-proclaimed prophets in Judea at this time (the version we get from the bible is likely a conglomerate of many preachers), and unreliable to base what-if scenarios off of. A better (and more reliable) PoD to change Christianity would be with Paul.
