"The modern radical spirit which would sweep away the Formula of Concord as a Confession of the Church, will not, in the end, be curbed, until it has swept away the Augsburg Confession, and the ancient Confessions of the Church--yea, not until it has crossed the borders of Scripture itself, and swept out of the Word whatsoever is not in accord with its own critical mode of thinking. The far-sighted rationalist theologian and Dresden court preacher, Ammon, grasped the logic of a mere spirit of progress, when he said: 'Experience teaches us that those who reject a Creed, will speedily reject the Scriptures themselves.'"
Theodore E. Schmauk and C. Theodore Benze, The Confessional Principle and the Confessions, as Embodying the Evangelical Confession of the Christian Church, Philadelphia: General Council Publication Board, 1911, p. 685.
