while I believe the Church teaching has never taught or sanctioned murder, one would have to have his head deeply buried in the sand to not know that many people were killed in various ways for “owning their own beliefs
That is not the question.
The question is “did Popes murder people for reading the Bible in the Middle Ages”.
The question is not, did a Pope ever somehow sanction a murder of someone who had some belief/ did some practice that the Church did not approve of. We know that this happened.
(You will also note I made a later post suggesting that maybe this query stemmed from the idea of someone being killed for not just reading a Bible but forming their own interpretation of it and proceeding to publicize that interpretation, which is a lot different from “killed for reading a Bible”.)
I’m all for having a reasoned discussion of what a particular Pope did, which means that the person discussing has either read all the surrounding history or is open to listening to a deeper discussion of it than “bad ol’ Catholic Church killed people”. That would be just as bad as me saying “bad ol’ Protestant Church killed Catholics for being Catholic” which indeed also happened, but there was a lot more context around it at that time.
If you have spent any time around certain categories of Baptists, which I have, some of them have these wildly oversimplified ideas about Catholicism and the evils that Popes did which are about on the same level as when Catholics accused Jewish people of crucifying Catholic children in their basements. This type of statement from some random Baptist falls in the same category to me unless and until said Baptist, or a similar Baptist, adds some context and depth to it, not someone else changing the entire scenario and adding depth in an attempt to make an apologia for a Baptist.
P.S. It’s also a fact that in the Middle Ages, most people had no access to a Bible and also couldn’t read, or couldn’t read well enough to comprehend a Bible, so those people who might be reading a Bible would tend to be relatively educated or wealthy people or clergy, who are also the ones who might likely go beyond just reading and come up with some incorrect/ heretical interpretation and start propagating it to the dismay of the hierarchy.
