Salams to All,
There is a subset of Christians (Unitarians) that celebrate Christmas as the birthday of a Prophet, not as a supernatural event. (Of course the actual date is not known so the Roman Church parked it on top of a pagan festival as a way to “christianize” it.). For Unitarians, Christmas isn’t much of a problem but Easter is quite awkward because no Unitarian believes that anyone can physically resurrect on this earth. It becomes a kind of generic spring festival/“good triumphs over evil” festival. (I always thought Unitarians should just drop Easter and celebrate Norouz instead because it would be more obvious to just celebrate the arrival of spring.) Trinitarian Christianity has very complicated doctrines and narratives that were written well after Prophet Jesus passed from the earth. Strangely enough, I’ve heard of many Muslims who do believe in the Virgin birth. I still haven’t figured that one out...
