The Lord's Supper as played out according to the Watchtower is a great act of rebellion against God, in at least 2 ways:
And when He had taken a cup and given thanks, He gave it to them, saying, “Drink from it, all of you; for this is My blood of the covenant, which is poured out for many for forgiveness of sins. Mt. 26: 27, 28
1. All are commanded to drink of the symbolic blood because it represents an irrevocable contract between the participant and God. Why "all" and not just 144K ?
2. Because the purpose of the contract is NOT for government positions in the kingdom per se, as the WT teaches, rather the purpose is clearly defined as "for forgiveness of sins". Since all have sinned, all must participate in the contract so that a death has occurred on their behalf for their personal sin debt.
When I was a regular pioneer, I used to mock Christians for their seemingly constant harping on the need for a "personal savior".
It finally made sense years later when I read a scripture that I NEVER heard quoted even one time at a Kingdom Hall.
Hebrews 9: 27 It is appointed unto man once to die, and then to face judgment.
The WT teaches a sort of collective judgment based on who is in the Organization and who isn't. The bible teaches that there will be a personal judgment, hence the need for a personal savior.
John 5: 28, 29 - Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, And shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation.
