*Many Protestant churches now celebrate Reformation Sunday on the Sunday on or before October 31. Some people, including the whole country of Slovenia, still celebrate Reformation Day on October 31, no matter what the day of the week.
On October 31, 1517, Martin Luther tacked his Ninety-Five Theses to the door of the Castle Church of Wittenberg, Germany. At the time, he was probably just hoping other professors and students at the University of Wittenberg would read it (since the church door was, in effect, the town bulletin board), and that it would perhaps lessen the sale of indulgences locally.
Instead, it’s now known as the start of the Reformation.
In fact, someone took the Ninety-Five Theses, translated them from Latin to German, and made copies using that brand new invention, the printing press. The ideas spread quickly, and the Reformation took hold.
To celebrate, you might take some time to learn about the Reformation and to learn the history behind the church you attend. The great highs and horrible lows of church history always remind me of a C. S. Lewis quote, from one of my favorite books, The Silver Chair: “‘You come of the Lord Adam and the Lady Eve,’ said Aslan. ‘And that is both honour enough to erect the head of the poorest beggar, and shame enough to bow the shoulders of the greatest emperor on earth. Be content.’”
“Make every effort to keep the unity of the Spirit through the bond of peace.”
