Are you saying that Judaism is pagan? I hope not.
I’m asking a rhetorical question.
Would Jesus celebrate Christmas? Let’s take it back to his time during the height of ancient Rome’s power.
The holiday equivalent would have been the Feast of Saturnalia for the Romans. During Jesus’ time would he have celebrated it? Absolutely not. He was an observant Jew - not a Roman or Christian or a Hellenized Jew. He celebrated Chanukah. Why? Because the Feast of Saturnalia was a pagan celebration. I’m sure some Romans back then would have denied that Saturnalia was pagan.
