I don’t celebrate Xmas either. When I review Scripture, history and current custom, what I find is a syncretic holiday even if you put aside the fact that Jesus was born in the fall of the year and not near the winter Solstice.
Of course people are free to do what they want and to justify it on any grounds, but that does not make it right. Jesus Himself rejected religiosity that was based on human traditions, and many Xmas traditions predate the birth of Our Savior.
I will not teach my children syncretism when I can teach them the truth.
Thank you for your comment, and God Bless you and yours!
