On October 31, 1517, a young monk approached the church in Wittenberg, Germany, and hung a document on the wooden door entitled “Disputation on the Power and Efficacy of Indulgences.” It was intended as an invitation to an academic discussion that he was organizing, but the two core beliefs of the Bible being the sole religious authority (not the Pope) and that salvation can only be attained by faith, not by deeds, set off the firestorm that is now known as The Protestant Reformation.

With this simple act, Martin Luther reminds us every All Hallow’s Eve that there really is no such thing as a “back row” Christian.
