I believe in the existence of a universe of suns and planets, among which there is one sun belonging to our planetary system; and that other suns, being more remote, are called stars; but that they are indeed suns to other planetary systems. I believe that the whole universe is NATURE, and that the word NATURE embraces the whole universe, and that God and Nature, so far as we can attach any rational idea to either, are perfectly synonymous terms. Hence I am not an Atheist, but a Pantheist; that is, instead of believing there is no God, I believe that in the abstract, all is God; and that all power that is, is in God, and that there is no power except that which proceeds from God. I believe that there can be no will or intelligence where there is no sense; and no sense where there are no organs of sense; and hence sense, will, and intelligence, is the effect, and not the cause, of organization. I believe in all that logically results from these premises, whether good, bad, or indifferent. Hence, I believe, that God is all in all; and that it is in God we live, move, and have our being; and that the whole duty of man consists in living as long as he can, and in promoting as much happiness as he can while he lives.

— Abner Kneeland, “A Philosophical Creed,” written at Hebron, N.H., May 28, 1833, Boston Investigator, July 12, 1833

The biography of Abner Kneeland by Stephan Papa and Peter Hughes in the Dictionary of Unitarian & Universalist Biography reports:

Abner Kneeland (April 7, 1774-August 27, 1844), a pioneer evangelist and minister, was a powerful, if inconsistent, advocate of Universalism for a quarter of a century beginning with the Winchester Convention of 1803. His religious doubts and ever-changing theology posed challenges to his Universalist friends and colleagues. Ultimately he was led beyond Christianity. After he left the Universalist fellowship he became the last man to be convicted of blasphemy in the state of Massachusetts. Clinton Lee Scott wrote that Kneeland was “the most controversial character ever ordained to the Universalist ministry. He anticipated by a century opinions now held without opposition.”
