As a well educated Christian, Bible reading and believing, you've probably came across the different studies about the origins of Christmas, which in reality is not a Christian observation at all. In fact, there's nothing in "Christ-Mas" that is Christian [not Biblically supported] other than the celebrations of Christ's birth, which was actually not even close to this time of the year, regardless. And it was added and justified by the Roman Catholic Church to attempt to get Christians to okay the celebration and draw them into it. Again, the birth of Jesus Christ in the scriptures does not take place in the month of December or even close, and after Jesus ascended into heaven there's no indication in any text in the New Testament of the disciples or apostles celebrating Jesus' birth either. I'll leave any further research in your hands to do, it's better if you look for these texts yourself.
The rituals in "Christ-Mas" are invoking your time and praise to a handful of idols, and in some cases even Satanic in origin. Other than bringing the family together, there's really no spiritual value in celebrating Christmas. I have made the change in my life; I no longer celebrate these rituals either mentally or physically. I've freed myself from them (Gal. 4:6-11).
There's a nice amplified study on YouTube, via The Prophecy Club, that will bring to the light all of the important texts in the Bible regarding the truth behind "Christ-Mas" and other pagan celebrations which today are called "holidays;"
May God richly bless you with His Holy Spirit!
But before you watch this presentation I'll leave you with this Jeremiah text:
Jeremiah 10:1-18 Amplified Bible (AMP):
1 Hear the word which the Lord speaks to you, O house of Israel.
