Religion Prescribed for Army and Navy

According the the Library of Congress website:

Army
Congress was apprehensive about the moral condition of the American army and navy and took steps to see that Christian morality prevailed in both organizations. In the Articles of War, seen below, governing the conduct of the Continental Army (seen above) (adopted, June 30, 1775; revised, September 20, 1776), Congress devoted three of the four articles in the first section to the religious nurture of the troops. Article 2 "earnestly recommended to all officers and soldiers to attend divine services." Punishment was prescribed for those who behaved "indecently or irreverently" in churches, including courts-martial, fines and imprisonments. Chaplains who deserted their troops were to be court-martialed.

Navy
Congress particularly feared the navy as a source of moral corruption and demanded that skippers of American ships make their men behave. The first article in Rules and Regulations of the Navy (below), adopted on November 28, 1775, ordered all commanders "to be very vigilant . . . to discountenance and suppress all dissolute, immoral and disorderly practices." The second article required those same commanders "to take care, that divine services be performed twice a day on board, and a sermon preached on Sundays." Article 3 prescribed punishments for swearers and blasphemers: officers were to be fined and common sailors were to be forced "to wear a wooden collar or some other shameful badge of distinction."
