We thought we knew the Bible. We had a dozen rehearsed passages filed away. If anyone had asked me when Isaiah lived or Michah or Habakuk or Ahab lived I would have needed to look it up and then forgot it just as fast. I had been exposed to these things (at least a WT take on it) but they weren't necessary to remember. I didn't need to see how the pieces fit together, I had been told what to believe and what to conclude. The WT system provided an appearance of Bible study that satisfied the mind sufficiently to not question the WT scholars who printed the material.
I was actually asked by a householder if I had read the Gnostic Gospels once, when I was about 20. I said NO!, still pretending to know what they were, and said they were demon inspired. (default response). I didn't have a clue that for many Christians these writings were their "Bible." My response of course ended the conversation, which is ultimately what I wanted so as to not sound stupid anymore. I did however go to the library secretly and look up the subject and what I read left an impression that resurfaced years later.
