You think someone can be condemned if they don't believe Jesus was born December 25th, in spite of the strong scriptural evidence that Jesus was in fact NOT born in December?
You don't seem to be making sure of the more important things. When I examine the scriptures with regard to what you are saying, I find:
"One man judges one day as above another; another man judges one day as all others; let each man be fully convinced in his own mind." Romans 13:5
"You are scrupulously observing days and months and seasons and years. I fear for you, that somehow I have toiled to no purpose respecting you." Galatians 4:10,11
Quite frankly, it isn't important what day Jesus was born. What is important is that he died, and rose and reigns as King.
The early Christians did not maintain December 25th as the "birthday" of Jesus. Early church fathers like Clement of Alexandria thought Jesus was born in November, other documents indicate maybe March.
December 25th was eventually chosen by the Church because that corresponded with the Roman festival of Saturnalia. It's clearly pagan in origin. As are the Christmas trees, the mistletoe, the "yule log", and other traditions associated with Christmas. They're all pagan in origin.
We should be wary about mixing light with dark, Christ with Belial. But if you insist on celebrating Christmas anyway, you have no standing to judge those who are honest about it.
Well, I can see you are full of opinions.

Come back after you've dumped all your opinions and want to discuss questions intelligently.
