@rattigan: the Bible clearly instructs to do this ‘whenever’ two or more followers of Christ come together for worship. If you are a Christian, you should partake whenever you worship in a group.
JWs don’t believe in the divinity of Christ, so whatever they do at the memorial has nothing to do with Christ’s divine nature, they are focused on the ‘anointed’ although that’s recently been modified to only include the ‘governing body’, because the anointed (aka governing body) rule the JWs on earth as kings and according to their doctrine will in heaven too.
In other words, it’s a power play to confirm the ‘rulers’ of the JW on earth, although with more and more partakers, that kind of backfired on them. I remember back in the day, the partakers were always old, elders and circuit overseers or their family members, and if you partook (there was always some crazy brother or sister) they were called into the backroom for the next few meetings to assess their spirituality with subsequent approval from Bethel based on their report. That changed later in the late 90s I believe when they said they would no longer do these assessments and the elders were told to kind of figure it out on their own whether they wanted to count them.
But I know two people that were disfellowshipped for continuing to claim they were anointed after the elders told them they weren’t approved, I was too young to understand, but one of them was a woman that said Jehovah was talking directly to her, which I now understand is a mental issue, but the window washers said it was demons which you could get from playing tapes backwards (I was scared of those double self-reversing hifi setups and 8-track players, because ‘what if’ instead of rewinding, it played music backwards) Yeah, crazy stuff used to go on in the 80s and 90s.
