NO LEGISLATIVE DECISIONS OF RELIGIOUS CONTROVERSIES
United States Senate Report on Sunday Mails, 1829
They appear in many instances to lay it down as an axiom that the practise [of Sunday labor] is a violation of the LAW OF GOD. Should Congress in legislative capacity adopt the sentiment, it would establish the principle that the legislature is a proper tribunal to determine what are the laws of God. It would involve a LEGISLATIVE DECISION ON A RELIGIOUS CONTROVERSY, and on a point in which good citizens may honestly differ in opinion, without disturbing the peace of society or endangering its liberties. If this principle is once introduced, it will be IMPOSSIBLE TO DEFINE ITS BOUNDS.
