My family celebrated Christmas when I was young, but we stopped based on a change in my parents' convictions. Even though I missed getting the presents, I didn't feel deprived of what really mattered. I don't think my psyche has been permanently damaged either.
I did not celebrate Christmas for many years as an adult because it was very natural to adopt my parents' view. But there were other reasons for non-celebration. During an especially rough time, the thought of pasting on a happy holiday face so I wouldn't be a downer was more than I could bear. It would have been the height of hypocrisy given the current circumstances. But time has passed, and I have changed. Now my daughter and I have our own rather low-key Christmas celebration.
I'm not suggesting we abstain from civil discourse about the pros and cons of celebrating Christmas. Dialogue about differing ideas can be profitable. But there is more to being a Christian than what we do or don't do on December 25.
In the fullness of time, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons. (Gal. 4:4-5)
We can rejoice that the Seed of the woman came and crushed the head of the serpent even if we don't agree on the month Jesus was born. We can meditate on the incarnation and have our minds blown away by the mystery of the hypostatic union in December as well as the rest of the year. We can be thankful that God has saved us from every tribe, tongue, and nation which includes those who celebrate Christmas and those who don't.
The good new of Jesus Christ far outweighs what we may disagree on regarding a single day of the year. May we hold fast to the gospel, our unity in Christ, and the blessing of Christian liberty. May we give thanks to the Lord for all His wondrous deeds. And we can do this no matter what we do or don't do on December 25.
