Sample from the article CMRosary linked to:
During the Protestant Reformation, the Catholic Church was persecuted and the Holy See appointed an apostolic vicar to govern the bishop-less dioceses north of the Rhine and Waal. Protestants occupied most church buildings, and those remaining were confiscated by the government of the Dutch Republic, which favoured the Dutch Reformed Church.[13][not in citation given (See discussion.)]

I didn’t link anything and so the Caucus designation should remain.
Otherwise, any and every caucus post could instantly be invalidated by somebody posting a link that so much as mentioned a Protestant denomination. And of course, all of us Christians are constantly making reference to Jews and Jewish Scriptures.
