“To turn away from the disputes of the Catholics and the Protestants, of the Unitarian and the Trinitarian, of old school and new school, and come to the plain words of Jesus of Nazareth, Christianity is a simple thing, very simple. It is absolute, pure morality; absolute, pure religion, the love of man; the love of God acting without let or hindrance. The only creed it lays down is the great truth which springs up spontaneous in the holy heart—there is a God. Its watchword is: Be perfect as your Father in heaven. The only form it demands is a divine life; doing the best thing in the best way, from the highest motives; perfect obedience to the great law of God. Its sanction is the voice of God in your heart, the perpetual presence of him who made us, Christ and the Father abiding in us. All this is very simple—a little child can understand it; very beautiful—the loftiest mind can find nothing so lovely.”
—Theodore Parker, from H.S. Commager, Theodore Parker: An Anthology, p. 56.
