The general Principles, on which the Fathers Atchieved Independence, were the only Principles in which that beautiful Assembly of young Gentlemen could Unite, and these Principles only could be intended by them in their Address, or by me in my Answer. And what were these general Principles? I answer, the general Principles of Christianity, in which all those Sects were united: And the general Principles of English and American Liberty, in which all those young Men United, and which had United all Parties in America, in Majorities sufficient to assert and maintain her Independence. Now I will avow, that I then believed, and now believe, that those general Principles of Christianity, are as eternal and immutable, as the Existence and Attributes of God; and that those Principles of Liberty, are as unalterable as human Nature and our terrestrial, mundane System. I could therefore safely say, consistently with all my then and present Information, that I believed they would never make Discoveries in contradiction to these general Principles."
-- John Adams, letter to the young men of the Philadelphia, 1798
