Years ago we used to attend a church that made a big deal out of celebrating Reformation Day, not Halloween. As you probably know, this holiday commemorates Martin Luther's nailing his 95 theses to a church door in Wittenberg on October 31, 1517.
I was explaining this to my friend, Rich, back then and he said, "Well, no wonder they didn't answer the door, they thought it was trick or treaters."
By the way, do you still not believe in coincidences? As I was getting ready to type this post, Rich started knocking on our door.
