The celebration of Christmas on December 25 is widely observed across various beliefs, yet it is not supported by any divine command to commemorate the birth of Jesus on that specific date. Historical attempts to justify December 25 as the date of His birth often rely on calculations, such as those by John Chrysostom, who suggested that Zacharias' second course of service in the Temple and subsequent events led to Jesus' conception on March 25, resulting in a birth date of December 25. However, these calculations are flawed due to the omission of the additional weeks of service during the holy days, which shifts the timing and suggests a different period for His conception and birth. Furthermore, the proximity of December 25 to the pagan Saturnalia festival raises concerns about the syncretism of pagan customs into the observance, a fact that some Christian scholars acknowledge but justify by claiming the current meaning of Christmas overrides its historical pagan roots. Despite these arguments, there remains no scriptural basis for selecting December 25 as the date to honor His birth.

Many people are aware of the contradictions surrounding Christmas, particularly the traditional claim that Jesus was born on December 25. It is acknowledged that He could not have been born around the winter solstice. In the early fourth century, the Catholic Church combined the Roman winter solstice festival, Saturnalia, with a celebration of His birth to ease the transition of new converts to Christianity. Despite this, the celebration continues on December 25, even though it is not supported by biblical command or suggestion to commemorate the Savior's birth on this date.

December 25th holds a central place in the discussion of Christmas as the culmination of a historical blending process rather than a biblically rooted observance. Christmas traces back to ancient Rome's Saturnalia, a winter festival near the solstice marked by gift-giving and feasting, and later absorbed elements from the Germanic yuletide tradition, including evergreen trees and lights meant to ward off darkness and evil spirits during a twelve-day celebration beginning around December 20th and extending toward the New Year. As Christianity spread through Europe, the Catholic Church found itself unable to stop members from continuing these entrenched pagan customs, so instead of eliminating them, the Church merged the celebration of the birth of Jesus Christ with the existing festivities and assigned it to December 25th. This blending explains modern traditions such as Santa Claus, modeled after the Norse god Odin, and Christmas lights, which originated as a means of warding off evil spirits—a meaning still known even among ordinary people, as illustrated by a childhood friend whose family understood the pagan symbolism behind the lights decades ago. This origin story is presented as evidence that Christmas has no basis in truth, reinforced by John 4:24, which states that God is Spirit and must be worshiped in spirit and truth, implying that God would never command observance of something rooted in deception. Despite this, the overwhelming majority of the population, cited at 93% according to a 2019 Gallup poll, continues to celebrate Christmas, spending enormous sums of money and increasingly extending the season earlier each year. Many people admit privately that they recognize the pagan roots of the holiday yet continue participating for the sake of family tradition, illustrating a broader spiritual blindness described in scriptures such as Matthew 13:10-17 and Isaiah 44:18, where people's hearts and minds remain closed even when truth is presented plainly. December 25th thus serves as a case study for the larger theme of calling and discernment. Those without God's calling lack the spiritual capacity to recognize the falseness of the holiday, no matter how intelligent or biblically knowledgeable they may otherwise be, as shown by examples of respected teachers who accept other truths yet embrace Christmas or reject the Sabbath. This inability underscores the necessity of guarding one's calling once God has opened the mind to truth, as emphasized in II Peter 1:10 and I Timothy 4:14-16. The Christmas season becomes a test of resolve, particularly in protecting children from peer pressure and family expectations, requiring firmness rooted in the understanding that loving God must take precedence over social comfort or tradition.
