According to the July 1, 1973 Watchtower magazine, only the Watchtower organization can understand the deep meaning of the Scriptures. It remains a "sealed book" to everyone else.
As ex-members, it's easy to recognize such a statement for how ridiculous it truly is. It now seems unimaginable that we really believed that a dozen or so men in New York were granted special powers from God, allowing them alone to interpret Scripture.
