While Brother glossed over this passage quickly, the quote from St. Robert Bellarmine is very solid: "They cannot enter a Church of which they are ignorant."
Yes. Here's another one:
St. Robert Bellarmine, De Gratia Et Libero Arbitrio, Book 4, Chap. 10: “… in every matter the mode of desiring corresponds to the mode of knowing; for desire follows knowledge, nor is it possible that someone desires an unknown thing.”
In other words: "Out of sight, out of mind". This should be common sense so the fact that so many people believe in BOD/BOB (the bad versions of it), is evidence that there is something spiritual going on with it.
