Q: Isn’t Christmas a pagan holiday? After all it originated with the Romans celebrating the birth of their god Saturn on December 25.
A: No. But a lot depends upon what you are celebrating.
If you are celebrating the birth of Saturn then it is. If you are focused upon Santa Claus and his reindeer then it is something else. But if you are celebrating the birth of Jesus Christ then it is Christian, no matter what day it is celebrated on.
The Bible doesn’t really tell us what day Jesus was actually born on. The only scriptural clue is that there were shepherds in the fields tending their sheep that night. That means the first Christmas Eve happened sometime during a span from May to early October. So we can be somewhat certain that it did not happen on the 25th of December.
