The substance of it is contained in the Declaration of Rights, and the Violations of those Rights, in the journals of Congress in 1774. Indeed, the essence of it is contained in a pamphlet voted and printed by the town of Boston before the first Congress met, composed by James Otis, as I suppose, in one of his lucid intervals, and pruned and polished by Samuel Adams." (John Adams's Works, II. 514).Franklin approved Samuel Adams' Rights of the Colonists:
To the sentiments expressed in the report of the committee, and adopted by the inhabitants of the town, he fully assented. This is proved by his sending a copy of the proceedings to the press, as soon as he received it in London, with a prefatory notice written by himself. The pamphlet was entitled "The Votes and Proceedings of the Freeholders and other Inhabitants of the Town of Boston, in Town Meeting assembled, according to Law. Published by Order of the Town." -- Sparks.Here, John Adams writes Christianity is The Law of Nature. Likewise, Yahweh is the Law of Nations in Article 1, section 8 of the Constitution:
