Re: If no seperation of church & state....
In a letter dated January 1, 1802 Thomas Jefferson wrote this to the Danbury Baptist Association in Connecticut:
"I contemplate with sovereign reverence that act of the 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"
This was published in a Massachusetts newspaper at the time. Jefferson's metaphor has been cited by the Supreme Court a couple times.
