A religion tends to be a group of people who thinks the same, and if anyone questions anything they get kicked out. What Jesus teaches tends to go against this. Reflecting, questioning, debating etc not only keep religion from being boring, but lead to growth and (at least in my case) bring one closer to God

Therefore when the Vatican has rescinded his authority to teach Catholic theology because of his book, Infallible? An Inquiry (1971) it was most upsetting!
