So I wanted to know what everyone here thinks about it. (Sorry this was a long one)
Hello! Just my perspective. From the date given in the book of Luke for Zechariah being in the temple it's possible to work out when Jesus was born. It equates to the Biblical Feast of Tabernacles in September, which makes sense given that Jesus came to fulfill the Law and the prophets. I don't believe that any of the Old Testament Feasts are in December.
How the Western World came to celebrate Jesus birthday on 25th December could probably be debated for a long long time with no end in sight.
There is a Pagan mid winter festival in December, the Feast of Yule. Many of it's features have been directly incorporated into the modern Christmas experience. There are many features of Christmas which have nothing to do with Jesus or the bible, flying reindeer for example.
It's also complicated that many if not most of the people who celebrate the Christmas Festival annually have no interest in Jesus or Christianity. It is a festival now associated with consumerism and excess, the 'Christian' elements of which have been steadily elbowed out over many years.
At Christmas I believe Church attendance increases slightly, as does alcohol abuse, DUI, domestic violence complaints and the number of very long and outdated movies on TV. As sadly does the suicide rate.
Christmas Trees seem to be a popular feature of Christmas, the origins of which churches and Christians can't agree on. It clearly isn't a feature of worship encouraged in the bible.
Some people say the church deliberately incorporated elements of paganism into such festivals to make Christianity more palatable to pagan communities as the church became a state church. A history perhaps churches can't agree on, but there may be some clear anecdotal evidence that it is true in some of what I mentioned above.
So perhaps 25 December is just a popular traditional festival with no biblical authority.
Some Christians perhaps enjoy it and have happy memories of it, some perhaps find it objectionable. Personally I would say that no-one should be compelled to celebrate or not to celebrate it. Follow your conscience. Everyone will give an account of themselves to God one day.
For those who think it's a Pagan festival that should be repented of, I think it's too ingrained in Western Church culture now to be thrown out.
But I would say to remember that although Christmas is a happy time for many, for others it is a very miserable time. For lonely, poor or depressed people it can be a living hell. So we must remember our Lord's instruction, whatever we did for the least of these we did for him.
God Bless
