LOL, I might take that comment at face value were it coming from someone who I knew was careful .
I notice you forgot to mention the alternative which is faith in the heresy of Self and Self Alone that assures those who embrace said heresy Jesus Christ personally approves of interpretations of His Word by Billy Sunday, Billy Graham, Sister Aimee, David Koresh, Manny, Moe, & Jack, and of course ones own personal interpretation as well.
The strong delusion of Self Alone that leads inevitably to embracing the social norms of the day or to the worship of ones own Most High and Holy Self is literally the oldest lie in the book.
In spite of the rare exceptions and well known limits, relying on the Imprimatur of The Church Jesus Christ Himself established it is clearly a guideline grounded in what Scripture teaches with regard to the Church being the pillar and bulwark of the Faith. Obeying His Word is by definition being careful whether those who are under a strong delusion can grasp that Truth or not.
I find myself in the strange position of agreeing with Boatbums. I have read a number of books that had the Nihil Obstat that left me scratching my head over their orthodoxy.
