Today we honor the 495th anniversary of the debut of the 95 Theses, a courageous and necessary defense of the authority of Scripture, the priority of biblical faith and the beauty of God's grace. Martin Luther, a flawed but brave saint, posted these theses against a Truth-less world with powerful, corrupted and legalist churches.
In grad school, I learned of a clever song about the life of Martin Luther and the theological significance of the Reformation . . . to the tune of Mary Poppins' "Supercalifragilisticexpalidocious." I actually sang it in church for an evening service (see above) a few years ago. Below is a video of a recording of the song, but my musical interpretation was much more polka-oriented.
Remember: sola scriptura, sola fide, sola gratia!
