In british royal throne succession line history?

okay it is to my understanding that for the royal future king to succeed to the throne he must marry an anglican/protestant woman right?but i was wondering that in history was there ever a king in line for the throne who went against that rule and sacrificed the throne?just out of curiosity....let's say that the king married an anglican/protestant woman but then the got divorced.and then he remarried again but the woman was roman catholic?would they overthrow him or something?
