"I have never united myself to any church because I have found difficulty in giving my assent, without mental reservation, to the long, complicated statements of Christian doctrine which characterize their articles of belief and confessions of faith. When any church will inscribe over its altar, as its sole qualification for membership, the Savior's condensed statement of the substance of both law and Gospel, 'Thou shalt love the Lord thy God with all thy heart, and thy neighbor as thyself,' that church will I join with all my heart and soul."
