If Jesus existed somewhere and looked at Christmas, he would probably hate it. Using a ritual that is pagan in it's origin (ancient Roman religion and myth) to celebrate his birthday must be the worst offense to his teachings. All Christians would probably go to hell for that.
The specific connection with the Roman festivals (either the Saturnalia or the solar festival) is widely quoted, but historically, there's not much evidence for it aside from it falling on the same time of the year (especially the solar festival, since the earliest historical sources for that come from a time when the celebration of Christmas was already in place) and most early Christians living within the Roman Empire.
And the entire "pagan holiday which the Christians repurposed" narrative is also kinda iffy, seeing as Christmas was already celebrated before the Church became a political institution (and therefore had no power to impose it on anyone). I would rather lean towards pagan converts bringing their perceptions in. The Winter Solstice (and the days around it) was a major festivity in most, if not all, European cultures. Slaughter festivals and religious holidays associated with the Sun were the most common. So I'd say the early Christians took a date which was already symbolic to them and set the celebration of Christmas on it. Especially since it's not the actual anniversary of Jesus's birthday and I don't think there has ever been a time when it was considered to be anything else than symbolic.
Of course, once it was institutionalized, the Church went about adopting pagan practices and incorporating them into the celebrations (like the Christmas tree from Yule), so there's that. But for the origins, I would refrain from throwing around the "repurposed Roman holiday" narrative so freely.
ANYWAY.
OT: Well, if Jesus came back, then we wouldn't have that much time to change our ways anyway. Second Coming and all that.

I'd ask jesus what his REAL birthday was so christians could celebrate then, rather than the fake birthday on the celebration of winter solstice that was nicked from the pagans and co-opted into christian dogma, so people could go on selling chintzy crap without guilt
It has never been dogma.
