Let all your preaching be in the most simple and plainest manner; look not to the prince, but to the plain, simple, gross, unlearned people, of which cloth the prince also himself is made. If I, in my preaching, should have regard to Philip Melancthon and other learned doctors, then should I do but little good. I preach in the simplest manner to the unskillful, and that giveth content to all. Hebrew, Greek and Latin I spare until we learned ones come together.
Martin LutherWhen God's righteousness is mentioned in the gospel, it is God's action of declaring righteous the unrighteous sinner who has faith in Jesus Christ. The righteousness by which a person is justified (declared righteous) is not his own but that of another, Christ.
Martin LutherThis doctrine (justification) is the head and the cornerstone. It alone begets, nourishes, builds, preserves, and defends the church of God and without it the church of God cannot exist for one hour.
Martin Luther
