Thank you for the explanations. I understand now why it is what it is. What I don’t understand is why the church originally made Christmas the same day but not Easter when it’s a celebration of the resurrection, another fixed day.
A beautiful tradition, tied to Passover. Guess it’s too complicated for the mainstream.
Christmas as a Big Thing came along later and missed the whole moon thing plus who knows when Jesus was born under the Jewish calendar?
Easter is tied to Jesus’ actual day of resurrection, as measured in the Jewish calendar. We know the day because of the descriptions in the Gospels.
Christmas is a re-purposed Roman pagan holiday, taken over and renamed by the Church. It has no relationship to Jesus’ actual date of birth.
“another fixed day”
It is a fixed day(of the week), but not a fixed date.
