" For the doctrine of the Gospel that man is made righteous in the sight of God and saved by nothing but the pure grace of God, through the merits of Jesus Christ, is, as everybody knows, the most important doctrine, the marrow and substance of Christian teaching. Wherever this doctrine is not proclaimed, there is no Christ, no Gospel, no salvation; there men perish, and for such people it has been in vain that the Son of God has come into the world. "
