When the devil wants to cause offense against the true doctrine and faith, he does not do so through insignificant people, who do not rate highly with the world, but through those who are the very best, the wisest, the holiest, and the most learned.

When my heart is cold and I cannot pray as I should I scourge myself with the thought of the impiety and ingratitude of my enemies, the Pope and his accomplices and vermin, and Zwingli, so that my heart swells with the righteous indignation and hatred and I can say with warmth and vehemence: 'Holy be Thy Name, Thy Kingdom come, Thy Will be done!' And the hotter I grow the more ardent do my prayers become.

In ourselves, we are sinners, and yet through faith we are righteous by the imputation of God. For we trust him who promises to deliver us, and in the meantime struggle so that sin may not overwhelm us, but that we may stand up to it until he finally take it away from us.

Not only the adoration of images is idolatry, but also trust in one's own righteousness, works and merits, and putting confidence in riches and power. As the latter is the commonest, so it also is the most noxious.

Some plague the people with too long sermons; for the faculty of listening is a tender thing, and soon becomes weary and satiated.

The cross alone is our theology.

The inner man cannot be forced to do out of his own free will, what he should do, except the grace of God change the heart and make it willing.
