Five hundred years ago a young priest named Martin Luther nailed to the door of Wittenberg Cathedral a list of 95 debate points for anyone who wished to challenge him. Some of them were, in themselves, challenges to the prevailing practices and theology of the Catholic Church of the time.
His immediate intent was to spark discussion of what it means to be a follower of Christ and receive his blessing. The result was the publication of these points around Europe and revolution in views about the divine, the individual, and the practices and structures which link them. The world has not been the same since.
