because the Castle Church was very much at the center of life in the community of Wittenberg, the huge wooden doors through which everyone entered the church were the best place to post anything of any community interest, making them the all-purpose bulletin board for the small city. Innumerable other things were posted there of which history has taken no notice, but once we realize that Luther’s theses were posted in that context, we see their posting in a very different light. They were simply put on the bulletin board of that day, as anything posted must be.
