Hey, you're the one who believes in Satan.<quoted text>
Then, like you told me about biology and genetics, don't post stuff as fact if you're not really sure about it.
Part of the First Amendment says:
"Congress shall make no law respecting and establishment of religion or prohibiting the free exercise thereof."
Notice there are no words "separation," "church," or "state" found there.
There are discussions recorded in the Congressional Records, one if those discussions, recorded in 1799, was:
"We do not want in America what we had in Great Britain: we dont want one denomination running the nation. We will not all be Catholics, or Anglicans, or any other single denomination. We do want Gods principles, but we dont want one denomination running the nation."
"By our form of government, the Christian religion is the established religion; and all sects and denominations of Christians are placed on the same equal footing."
In 1802, there was a church called the Danbury Baptist Association based in Danbury, Connecticut. They heard rumors that other Christian denominations might become a "national denomination" so they wrote a letter to Jefferson, the current POTUS, about it. Of course they didn't want that. Jefferson wrote them back telling them that is not going to happen, he told them that "the First Amendment has erected a wall of separation between church and state."
And that laid dormant for many years. Nowadays all you hear is "separation of church and state", out of context or explanation as of it's part of the Constitution.
It's probably his doing.
