The Vatican has put together a museum exhibit on the Inquisition, supposedly trying to show that it was not as bad as its reputation. From this story, it still sounds pretty bad, with the exhibit showing instructions on how to persecute Protestants and an account about how one of these “heretics” was hanged.
It’s interesting to hear non-believers bring up the Inquisition as some sort of evidence against Christianity when Protestants–and, especially, us Lutherans–were some of its major victims.
