Those with historical senses could recall what Catholic-Lutheran actions used to be like. For instance, through the first centuries after the start of the Protestant Reformation, to be celebrated next year after 500 years, most of these actions were not close calls with whisker-thin margins. No, characteristically and regularly, linked with civil authorities, Catholics and Lutherans by the thousands killed each other. They got mixed up on both sides of a Thirty Yearsâ?? War, whose Christian devastation provides cheerless comparison to Muslim-related conflicts in Syria and elsewhere today.
