Those who condemn the Word of Absolution in favor of their own words are enthusiasts...

All this is the old devil and old serpent, who also turned Adam and Even into enthusiasts.  He led them away from God's outward Word to spiritualizing and self-pride.  And yet, he did this through other outward words.  In the same way, our enthusiasts today condemn the outward Word.  Yet they themselves are not silent.  They fill the world with their babbling and writings, as if the Spirit could not come through the apostles's writings and spoken Word, but has to come through their writings and words.  Why don't they leave out their own sermons and writings and let the Spirit Himself come to people without their writings before them, as they boast that He has come into them without the preaching of the Scriptures?
