Is it true that Christmas has nothing to do with Jesus?

from the old testament

• Isaiah 9:6 prophesies about the birth of Jesus, a prophecy used on many a Christmas card: "For to us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace."
• Micah 5:2 also brings attention to Jesus' birth by prophesying that He would be born in "Bethlehem Ephrathah."

from the new testament

• When Jesus was born, even the angels celebrated (Luke 2:13–14) because God had extended “peace among those with whom he is pleased.” Regardless of one’s view of Christmas, celebrating Jesus’ birth is valid and good.
• Jesus’ birth meant that the eternal Son of God (John 1:1) had taken on humanity (Philippians 2:6–7) so that He could be like us, except without sin (Hebrews 4:15). Being without sin meant that He could die for our sin (2 Corinthians 5:21). As the only way to escape God’s wrath (John 14:6; Romans 5:9), Jesus’ birth was the introduction of a major change for humanity’s relationship with God.
• Though His birth was important, salvation came through His death and resurrection. That is likely why we never learn about a birth celebration, only remembrances of His death and resurrection (1 Corinthians 11:23–26; Acts 2:42). That doesn’t mean we can’t celebrate a holiday like Christmas, but it does mean that such a celebration is optional.
• Guidance on this comes from Paul's letter to the Romans. He wrote, “One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind. The one who observes the day, observes it in honor of the Lord” (Romans 14:5–6a). Honoring the Lord in all that we do is the priority, whether we celebrate Christmas or not.
• Paul went on to say, “Why do you pass judgment on your brother? Or you, why do you despise your brother? For we will all stand before the judgment seat of God; for it is written, ‘As I live, says the Lord, every knee shall bow to me, and every tongue shall confess to God.’ So then each of us will give an account of himself to God” (Romans 14:10–12). Believers shouldn't look down on one another about the choice to celebrate Christmas. God knows their heart in the matter; we do not.

implications for today

Gossip is dangerous because even if it isn't true, it becomes "true" to the people hearing it if it's repeated enough times. This is the case with early views or legends, too; they're repeated so often that they are assumed to be true. An example is the idea that Christmas originated as a pagan winter solstice holiday. While some pagan customs may have influenced cultural practices, the day itself was intentionally established to honor Christ. Early scholars proposed the theory of it being a pagan winter solstice holiday, and it took root in popular culture, but most historians today reject it. In fact, secular and religious historians alike, agree that Christmas was intentionally created as a celebration of Jesus’ birth, so it is inherently about Christ.

But the original view is perpetuated—sometimes out of anti-Christians sentiment, some because they grew up hearing the older view. Others have mixed feelings about it, believing it to celebrate Jesus’ birth originally but as corrupted by a secular society. Christians must be understanding with one another about the choice to celebrate Christmas or not. What Scripture doesn't prescribe or condemn, we have the freedom to decide (Romans 14:5–6).

Whether we choose to celebrate Christmas or not, our focus should remain on honoring Jesus, not on proving a point or judging others. Our unity as believers and our witness to the world depend more on the condition of our hearts than on the day we observe.
