Sounds like a damage control meeting to me.
First they are trying to keep old ones from getting "discouraged" over having been lied to about living forever. Then, they are addressing those where perhaps baptized young. You must let your yes mean yes even when you did not understand what your yes meant because like myself, you were 14 ( or 9,10,11,12, 13, 15,16) and did not have a clue about the real world. It also addressed ANY baptized that don't understand what is NOW being asked. When you said "yes" to them it meant yes to what they taught at the time and yes to whatever they may change their teachings to in the future. That is like signing a contract that you can't change, but the other party can change at whim. That is why in the real world you have to be an adult and be of "right" mind to sign a contract. How many of us would have been baptized if it would have been put to us that way?
Lastly, they are addressing the problem of cable, satelite tv and the internet. Accourding to the WTS it does not matter what is discovered about the bible and it's authorship. Have you watched the discovery and history channels? Have you seen the info on the internet? Have you read about the lost books of the bible or even about who decided what writtings belonged in the bible? But....... Don't believe any of that! Oh no! Don't believe what scientist and historians say! Just believe the WTS.
The many years I went to the conventions, there seemed to be some damage control, but it seems much more blatent now, 7 years later. Is it just me? Am I just seeing it more clearly? Or does it seem that they are grasping for straws to keep the rank & file "in"?
