...of course my theory doesn't account for the contradiction in number of attendees. 63K vs 33K
phil--long story. Only the "higher class" of JWs participate in the "last supper", or communion, which they call the "memorial". This is celebrated once a year. This higher class is supposedly part of the 144,000 "anointed" christians...which supposedly accounts for all "true christians" from the time of Christ until the full number was FINALLY realized in 1935. From 1935 on a new class of believers called the "great crowd" was identified. Most JWs today obviously are of the 2nd class. But there are a LOT of the "anointed class" still around! somewhere around 8,500. This is hard to believe, since there weren't very many around back in 1935...and obviously one would think that most of them would be dead by now. But the answer for this that the Watchtower Society has provided was that some of these original members of the 144,000 have since turned their back on God, so they left a vacancy in the 144,000 that could be filled by a younger person.
In short, those who are "anointed", PARTAKE of the wine and bread at the Memorial. The rest of the JWs just attend and don't partake.
You still with me? I know it's pretty convoluted. Check out some of the articles that explain the 144,000 and the Great Crowd at freeminds.org.
