There is no wisdom save in truth. Truth is everlasting, but our ideas about truth are changeable. Only a little of the first fruits of wisdom, only a few fragments of the boundless heights, breadths and depths of truth, have I been able to gather.
Martin LutherOnce sure that the doctrine we teach is God's Word, once certain of this, we may build thereupon, and know that this cause shall and must remain; the devil shall not be able to overthrow it, much less the world be able to uproot it, how fiercely soever it rage.
Martin LutherIn short, I will preach it [the Word], teach it, write it, but I will constrain no man by force, for faith must come freely without compulsion. Take myself as an example. I opposed indulgences and all the papists, but never with force. I simply taught, preached, and wrote God's Word; otherwise I did nothing. And while I slept, or drank Wittenberg beer with my friends Philip and Amsdorf, the Word so greatly weakened the papacy that no prince or emperor ever inflicted such losses upon it. I did nothing; the Word did everything.
