Several people asked for the quotes used in the Reformation Day PM service. Here you go:
The prior quote comes from Martin Luther's Second Sermon upon his return to Wittenberg, in response to the radical “reforms” of Karlstadt, which is worth a longer read:
Once, when Paul came to Athens (Acts 17 [:16–32]), a mighty city, he found in the temple many ancient altars, and he went from one to the other and looked at them all, but he did not kick down a single one of them with his foot. Rather he stood up in the middle of the market place and said they were nothing but idolatrous things and begged the people to forsake them; yet he did not destroy one of them by force. When the Word took hold of their hearts, they forsook them of their own accord, and in consequence the thing fell of itself. Likewise, if I had seen them holding mass, I would have preached to them and admonished them. Had they heeded my admonition, I would have won them; if not, I would nevertheless not have torn them from it by the hair or employed any force, but simply allowed the Word to act and prayed for them. For the Word created heaven and earth and all things [Ps. 33:6]; the Word must do this thing, and not we poor sinners.
In short, I will preach it, 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 [cf. Mark 4:26–29], or drank Wittenberg beer with my friends Philipp 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. Had I desired to foment trouble, I could have brought great bloodshed upon Germany; indeed, I could have started such a game that even the emperor would not have been safe. But what would it have been? Mere fool’s play. I did nothing; I let the Word do its work. What do you suppose is Satan’s thought when one tries to do the thing by kicking up a row? He sits back in hell and thinks: Oh, what a fine game the poor fools are up to now! But when we spread the Word alone and let it alone do the work, that distresses him. For it is almighty, and takes captive the hearts, and when the hearts are captured the work will fall of itself.
