In celebration of the 500th anniversary of the Protestant Reformation, it is only fitting that I quote from Martin Luther himself–that truly flawed German monk God in his sovereignty and providence chose to change the religious and political landscape Europe and the rest of the world.
The following quotes is taken from a sermon Luther preached in Wittenberg in 522:
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 tot hem 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 one 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 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.
