As I watch many of the newscasts the annual barrage of Atheists trying to diminish the religious significance of the Christmas season seems to be growing. Atheists are wanting to erect their own monuments alongside nativity scenes and menorahs. The atheist cause is so weakened by there assault on religion than if the celebrated their own event. What they are doing by trying to diminish the Christmas Season is no different than the KKK marching during Martin Luther King Day, or the Nazi's marching on Rash Hashanah, or even Christians having an event on Ramadan. It does nothing to attempt to co-opt Christmas except to make atheists look like a bunch of intolerant jerks.
The Constitution guarantees the free exercise of religion. While it does prevent the establishment of a formal religion, it does not prevent a lawmaker or government body from acknowledging or even praising religion, or celebrating their own religious traditions. Many people quote Thomas Jefferson's letter and the mention of the need for a wall of separation between church and state. If you read Jefferson and much of the works of his colleagues it is very clear that his focus was to prevent government from interfering with religion. He never meant to purge religion from the government sphere. In fact, many of the founders believed that men of faith could be trusted more with the reigns of government.
I am not sure who said it first, but there is a saying that goes something like "Men of faith are tempered by the doctrines of their religious beliefs. Men without religion must be tempered by laws." Pope John Paul II said, "freedom is not the right to do whatever we want, it is the right to choose what we ought."
So don't be afraid to say Merry Christmas this season. Wishing you all the best.
