I'm re-reading 1984 and the similarities between the WTBS and the "party" astound me, but anyway, it made me think of the time when i started to get doubts (ThoughtCrime).
I remember once at this book study a sister commented about the 1914 and was reciting it's historical accuracy. Anyway, she went on to mention that the demons were probably learning everything about biblical prophecies from the WTBS. I was 13 at the time but the comment made me cringe, i was thinking "Why would superior beings need humans to interpret the bible for them?"
Anyway, this gave way to the questioning of other beliefs. Like the whole thing about how people wont have genitals in the paradise or all the other little doctrines that arent mentioned but are implied.
So anyway, what was your first apostasy?
