I'm reading a book named "The Burning Time" by Virginia Rounding which demonstrates vividly how the churches sought to control public attitudes and public behavior to the extent that people who disagreed with the church were burnt to death. Unsurprisingly the criteria of whether you were judged to be heretical changed over a very short period. As little as six years between 1532 and 1538.

I somehow feel that the likes of Rees-Mogg would be quite content with a return to that era.
