The elder really didn't express his true belief. He made use of the art of "theocratic warfare". You pressed him for an answer. Under pressure he gave you an answer ... in order to confuse you.
Schizm:
I believe that the elder gave an answer, not to confuse me (he's not that bright), but rather because I did catch him off guard. I don't think that there is any question about that. Whether that is his true belief or not is immaterial and I am not here, nor do I care, to guess whether or not he does believe it. The fact that he said it speaks for itself and the intelligent people on this board can determine for themeselves if that was a satisfactory answer or not. My guess is not.
To answer your question as to why the WTBS was an NGO, I don't think anyone truly knows why and I am not sure that it is important. Of course, if they were being truthful it was for a library card, although I doubt that very seriously (read the definition of lie/lying in the Insight book...*clue*: It's OK for the WTBS because nobody deserves the truth according to their thinking.) My guess is that it was to protect their worldwide holdings and to conform so that the UN and the nations of the world don't disband the WTBS. Like all organized religion they want to retain their money and their power. Nothing more, nothing less.
I think the important thing is that the incredibly hypocritical position by the Org makes them accountable, not only to Jehovah, but also to the millions of people that have sacraficed a normal life for an organization that has been a harlot like the rest of them. If they still want to maintain that it was simply for a library card, and nothing else, then at the very least they have been lukewarm and Jehovah will vomit them out of his mouth. If it is indeed harlotry, which I believe, then they will receive what the rest of "Christendom" receives. Disclaimer: I realize as I am writing this that the old dubbie doctrine is seeping in. I guess I don't even believe that shite anymore, but for the sake of using their own doctrine to judge them guilty, I plead guilty. They have judged others for years using their twisted logic, why not hold them accountable by their own words?
Sorry for the rant everyone...that issue just grinds my ass. Damn hypocrites!
