Martin Luther banned as Catholic reading material; ok, yes, I'm 50 days too late but I finally have something that goes along nicely with the 500 year anniversary (October 31st) of Luther nailing his theses to the door of the church and kicking the Reformation off.
Well, most books from that period have something to do with the Reformation, but this Index Librorum Prohibitorum is as blatant as it gets. Here we find John Calvin and Martin Luther (among others) officially banned by the Council of Trent.
Although previous Popes had tried their hands at banning books, the Council of Trent made it official throughout the Catholic faith and, in this 1587 Catholic book detailing and justifying the findings of the Council of Trent, we find the list of banned books and authors produced by the council.
I must not be the only one who finds this book interesting and relevant, it was for sale about an hour before someone bought it today.
