"Among the most inestimable of our blessings, also, is that... of liberty to worship our Creator in the way we think most agreeable to His will; a liberty deemed in other countries incompatible with good government and yet proved by our experience to be its best support." Religion (the duty which we owe to our Creator) that a man believes is most agreeable to God's will (rather than the recommendation or advice of the civil government) is good government's best support. In other words, those who trust in God, as recommended on the nation's coins and bills, by the U. S. Government, undermine, rather than support, good government. Let's remove "In God We Trust" from the coins and notes and improve our civil government.
