Blessed is the man that hath not walked in the way of the Sacramentarians, nor sat in the seat of the Zwinglians, nor followed the Council of the Zurichers.
Martin LutherPeter erred in life and in doctrine. Paul might have dismissed Peter's error as a matter of no consequence. But Paul saw that Peter's error would lead to the damage of the whole Church unless it were corrected. Therefore he withstood Peter to his face. The Church, Peter, the apostles, angels from heaven, are not to be heard unless they teach the genuine Word of God.
Martin LutherAs long as a man is persuaded that he can make even the smallest contribution to his salvation, he remains self-confident and does not utterly despair of himself, and so is not humbled before God. Such a man plans out for himself a position, an occasion, a work, which shall bring him final salvation, but which will not.
Martin LutherAt night always carry in your heart something from Holy Scriptures to bed with you, meditate upon it like a ruminant animal, and go softly to sleep; but this must not be too much, rather a little that may be well pondered and understood, that you may find a remnant of it in your mind when you rise in the morning.
Martin Luther
