The whole Seperation of Church and State was actually a letter written by Thomas Jefferson.. it is never mentioned in the Constitution. The 1st amendment has what is known as the 'establishment' clause... which has become incredibly warped in this time. it's gotten to the point where any city or county displaying anything religious is now "establishing" a religion. Look at LA.. the city had to remove the cross from the official seal because the ACLU threatened to sue.
