So why are Bibles still used in courtrooms. And why is "The whole truth, nothing but the truth...so help you God.........." used? True, you can opt out of using it, but isn't that a gross "Abuse" of the Church/State separation , the 1st Amendment ............
"The First Amendment to the United States Constitution provides that "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof ...." and Article VI specifies that "no religious Test shall ever be required as a Qualification to any Office or public Trust under the United States." The modern concept of a wholly secular government is sometimes credited to the writings of English philosopher John Locke, but the phrase "separation of church and state" in this context is generally traced to a January 1, 1802 letter by Thomas Jefferson, addressed to the Danbury Baptist Association in Connecticut, and published in a Massachusetts newspaper. Echoing the language of the founder of the first Baptist church in America, Roger Williams—who had written in 1644 of "[A] hedge or wall of separation between the garden of the church and the wilderness of the world"— Jefferson wrote, "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."
However, the Court has not always interpreted the constitutional principle as absolute, and the proper extent of separation between government and religion in the U.S. remains an ongoing subject of impassioned debate."
