Horace Bushnell was an American Congregational minister and theologian. As a preacher, Dr. Bushnell was very effective. Though not a dramatic orator, he was original, thoughtful and impressive in the pulpit. His theological position may be said to have been one of qualified revolt against the Calvinistic orthodoxy of his day. He criticized prevailing conceptions of the Trinity, the atonement, conversion, and the relations of the natural and the supernatural. Above all, he broke with the prevalent view which regarded theology as essentially intellectual in its appeal and demonstrable by processes of exact logical deduction. To his thinking its proper basis is to be found in the feelings and intuitions of humankind's spiritual nature. He had a marked influence upon theology in America, an influence not so much, possibly, in the direction of the modification of specific doctrines as in the impulse and tendency and general spirit which he imparted to theological thought. Dr Munger's estimate was that "He was a theologian as Copernicus was an astronomer; he changed the point of view, and thus not only changed everything, but pointed the way toward unity in theological thought. He was not exact, but he put God and humanity and the world into a relation that thought can accept while it goes on to state it more fully with ever growing knowledge. Other thinkers were moving in the same direction; he led the movement in New England, and wrought out a great deliverance. It was a work of extraordinary courage. Hardly a theologian in his denomination stood by him, and nearly all pronounced against him."
