In Pitman, New Jersey, just a little outside of Philadelphia, there is a billboard put up by the atheist group, American Atheists. It states, "Keep Saturn in Saturnalia". A "Keep Christ in Christmas" banner in Pitman was put up by private group overhanging a public street.
The Freedom from Religion Foundation paid for this billboard because a banner of it was denied the previous year by the Pitman government, even though the Pitman city government chose to display the "Keep Christ in Christmas" banner.
In other words, these city officials were showing unconstitutional favoritism to certain religious beliefs, creating a prohibited "establishment of religion."
The Constitution does not allow the government to promote a religion, no matter how it might want to do just that. This could be resolved quite easily, allow all groups to put up religious displays or no groups to put up religious displays.
The Pitman city government chose neither because they believed that the government should promote the religious beliefs of city government leaders.
Do they believe that Christianity couldn't compete in the marketplace of ideas without government help? Lastly the "Keep Saturn in Saturnalia" billboard had attempted arson against it.
This isn't that unusual. Countless billboards put up by atheist groups have been vandalized. Strange because those who believe in the bible state that the bible is a basis for morality, though it does not seem to rule out vandalism, apparently.
Now, you might be wondering why an atheist group put up a "Keep Saturn in Saturnalia" billboard? Simply, it is show the pagan and non-Christian origins of this holiday.
If Jesus was a real historical figure, then Christianity used common celebrations around the beginning of the winter solstice to mark his so called birthday. Saturn was one of these supposed gods worshiped around that time.
Those on the Christian right-wing demand that you celebrate Christmas their way, in a very religious observance. To them that is the only right way. So, if we are to "keep Christ in Christmas", shouldn't we "keep Saturn in Saturnalia"?
By the way, if you want to support keeping church and state separate and maybe contribute to such billboards, please support Americans United for the Separation of Church and State, Freedom from Religion Foundation and also American Atheists.
