From the Brief Statement of 1932
4. On the basis of the Holy Scriptures we teach the sublime article of the Holy Trinity; that is, we teach that the one true God, Deut. 6:4; 1 Cor. 8:4, is the Father and the Son and the Holy Ghost, three distinct persons, but of one and the same divine essence, equal in power, equal in eternity, equal in majesty, because each person possesses the one divine essence entire, Col. 2:9, Matt. 28:19. We hold that all teachers and communions that deny the doctrine of the Holy Trinity are outside the pale of the Christian Church. The Triune God is the God who is gracious to man, John 3:16-18, 1 Cor. 12:3. Since the Fall, no man can believe in the “fatherhood” of God except he believe in the eternal Son of God, who became man and reconciled us to God by His vicarious satisfaction, 1 John 2:23; John 14:6. Hence we warn against Unitarianism, which in our country has to a great extent impenetrated the sects and is being spread particularly also through the influence of the lodges.
