This makes no sense to me:
Greetings, dear Zombie... and peace to you!
1) You believe the JWs are doing it wrong because they observe and not partake
Yes...
2) If 7million odd of them are all doing it wrong then surely the whole thing is wrong
Yes...
3) Why go and partake at something that is wrong?
Because perhaps one... or even two... of them KNOW it's wrong... and WANT to do what's right... but are afraid... unsure... confused. But perhaps if they know they're not alone... perhaps they will find the COURAGE... to do what they KNOW they SHOULD be doing...
If you believe point 1 then surely the whole thing is pointless,
Perhaps. And perhaps you miss the point...
just have your own celebration or go to a catholic church or something?
First, while it does have it's own hypocrisies and errors to deal with, the Catholic Church doesn't stop people from partaking of the flesh and blood of Christ. True, they tie caveats to it (i.e., "When was your last confession, my son..."), and so "shut up the kingdom of the heavens" in that and other ways...
But we don't do it for us, dear one, but for THEM... the one... or two. True, they might not have got up the courage THIS year... but who knows what NEXT year will bring? Or the one after... or after that... until our Lord returns. And if he doesn't in our life time... so what? What have we expended but a few minutes of our time on behalf of those we love. Regardless of whether they love us... yet.
I hope you understand and, again, peace to you!
A slave of Christ,
