“Protestants would say the same thing.”
No, actually no Protestant says that about burning down a monastery in Utrecht. Try again.
“Right or wrong, at one time Catholics and Protestants had a similar set of values.”
False. Right or wrong, Catholics and Protestants committed similar actions. Their values were different.
The Catholics had already condemd Seretus to death as a heretic. He just escaped their paws. The Geneva “Calvinists” prosecuted Seretus under a court of law. Calvin sent a letter because of his failing health, agreeing.
The Catholics massacure the peaceful Huguenots and hundreds more through the Jesuits’ Spanish Inquisition. There is far more. Don’t try to white wash Catholic history.
