Shifting advice coupled with dogmatic and unflinching posturing of authority provides ample space for fucking wingnuts to spout nonsense. It even works against religions -- this sort of thing led to the protestant reformation. "I am infallible, but the last Pope was wrong..."

They gained power because the Mother Church discredited itself through hypocrisy, corruption, and self-contradiction.
