Commencing rant.
"He started talking about how the Organization doesn't have everything correct and they're starting to acknowledge it. How the meeting format has changed, focusing less on 'details' and more on how to live a good life."
"He also said it he doesn't like the term 'the truth', and thinks it's a presumptuous term, because they don't have 100% truth ."
"We have had some wrong expectations about the end. But we are more concerned with obeying Jesus and saving lives than with avoiding criticism. - w2013 1/15, p. 8"
"We agree with the sentiment of longtime Witness A. H. Macmillan, who said: "I learned that we should admit our mistakes and continue searching God's Word for more enlightenment.""
All the above would be well and good IF the Society didn't require total and unquestioning acceptance of whatever "new light" appeared in the latest WT or was announced at some special meeting. No matter what you were REQUIRED to believe yesterday or might be REQUIRED to believe tomorrow, even though some of those beliefs directly affect peoples' very lives. "Don't bother to ponder, reason, or do outside research on spiritual matters. We have brothers at Bethel who are assigned to do just that! We'll let you know what to think. Don't worry your pretty little heads."
The Society values "unity" above freedom of conscience and a personal relationship with Jesus. They are presumptious to an astonishing degree, and seem determined to be the masters of your faith. They are spiritual bullies in a very real sense, and I hope they pay a heavy price in the end.
Rant completed. Resuming normal operations.
For what it's worth, I agree with the other posters who advised you to be very careful with this "friend." He may be setting you up, even unintentionally. If he repeats anything you've said, even innocently, it could easily lead to an investigation into your "apostate leanings." He may feel compelled to jump on the bandwagon to deflect questions about his own thinking. There is no way this would end well for you. I highly recommend you be as noncommittal as possible. Say little and avoid conversations like this like the plague, unless you are ready to be out of the Borg completely and officially.
