A number of factors-including past religious beliefs or even mental or emotional imbalance-might cause some to assume mistakenly that they have the heavenly calling.
Well, we knew they'd have to come up with some sort of lame-assed excuse as to why the numbers are going up instead of declining and given their pitiful past record, this latest drivel comes as no real surprise. Forget the fact that the bible itself gives no "limit" as to how many go to heaven or that it's supposed to be a personal and one-on-one relationship with God that plays into it. Nooooooo. From this time forward, any newbies who dare to start taking the emblems at the Memorial will be branded as 'mentally and/or emotionall unbalanced' and will be mocked and virtually shunned by the rest of the congregation. And if these people want to continue to be Witnesses in good standing, the not-so-subtle message is quite clear: 'Knock it off if you know what's good for you."
Did the Slobbering Body members not foresee this when they opened the gates a few years ago stating that 1935 wasn't necessarily the cut off date to be considered 'annointed'? What the hell did they think was going to happen?
We thus have noway of knowing the exact number of anointed ones on earth; nor do we need to know.
Is that so? They why have they kept an exact count of how many partake of the emblems for the last 80 or 90 years? Obviously, they felt that they did 'need to know' the 'exact number of anointed', or there would have been no point to tracking the numbers all these years. Only now, when the numbers don't quite tally up with their bullshit very selective doctrine are they claiming that the numbers 'don't really need to know the numbers'. That way, when the number of partakers continues to go up, everyone will simply assume that the person is off their rocker. 
The Governing Body does not keep a list of all partakers, for it does not maintain a global network of anointed ones.
Which is quite interesting considering they claim that the 'Faithful and Discreet Slave' is referring to the 'annointed' ones. In a study article a couple of years ago, they claimed that those of the anointed ones don't have any more 'Holy Spirit' than the average Dub which is really bizarre because that's basically the only difference between the two groups. According to the GB, "...The Spirit Himself bears witness with our spirit that we are children of God." (Roman 8:16). Since the Society teaches that this scripture does not apply to the 'Great Crowd', then how exactly can they claim that the average anointed person doesn't have any more 'Holy Spirit' than the group of those who (supposedly) have the earthly hope? Ya......better smoke a couple of joints after reading that one. 
This is another prime example of the Watchtower's retarded doctrines coming back to bite them in the ass. If Rutherfraud (one of the best cases of an emotionally and mentally unbalanced individual I know of) had never invented the 'two class' system of Christians, none of this would even be an issue. But because they had already invented the doctrine of only 144,000 going to heaven, he had to come up with some excuse as to why the numbers weren't jiving with their doctrine. And presto! You've got another insane doctrine to defend and which will inevitably embarass the Borg somewhere down the road.
Should be interesting to see what the numbers are for next year!
