The Catholic Church never banned anyone from reading the Bible; nor is the posted sermon an attack on he Bible. It is an attack on sola scriptura. Sola scriptura is a belief, a doctrine, and perhaps a methodology. It is NOT the Bible. The Bible is the Bible, and sola scriptura is a doctrine that Protestants have slapped onto the Bible.
I believe that sermon is a prime example of the prescience of the Holy Spirit guiding the Church that He would try, through Christ’s church to protect His flock from the intruders who would lead them outside the fold and thus endanger them.
