One of the Witness rebuttals that is used to belittle the Christmas holiday is the one where they say that people reduce Jesus Christ to being just a baby in a manger, whereas the Witnesses recognize him as a Mighty King, a much more accurate and current way to view Jesus.
A baby in a manger is a sweet sight on any day, it's true, but more is going on than meets the eye in the case of Jesus. This particular baby is the FIRST baby to have been born without an earthly father, the immaculate conception. Adam was most likely an adult and we may never know any more about that. But, thousands of years have passed and there hasn't been anything like the conception of Jesus.
No, the date that we observe Christ's birth is most likely off, but the observance and recognition of the exceptional event is, in my opinion, worthwhile and, to steal a word from the WT, God-honoring.
Why do the Witnesses get to belittle a day that brings many to contemplate the virgin birth, the arrival of the Jewish Messiah and possibly the only day out of the year that might cause people to wonder who that baby really was?
