Constitution Bill of Rights Amendment ICongress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Constitution does not say Separation of Church and State, nor does the 1st amendment. The term was first used by Jefferson in 1802 in a letter to the Danbury Baptist Association. "whole American people which declared that their legislature should "make no law respecting an establishment of religion, or prohibiting the free exercise thereof," thus building a wall of separation between Church & State." http://www.loc.gov/loc/lcib/9806/danpre.html
With that established, we have the freedom of religion but the government cannot establish a religion. Separation of church and state represents the wall built between government and religion. Many will quote something from the constitution without researching what it actually says. Our government leaders have misquoted the constitution. Many people also confuse faith with religion. Faith is the belief where Religion is the worship. A church is a body of people coming together to share their worship. The building they meet in just happens to be called a church.
My intention is not to offend, but to inform. If I was wrong about something, I would want someone to set me straight on my error.
