Jesus issued a command to all his disciples '' keep doing this in rememberance of me".
I do not recollect any mention of him saying '' Oh! while I'm on the subject don't all of you partake ,some of you,the majority,just sit and stare at the wine and wafers and say pass it on. However, don't bother your minds about it just yet because,that bit about the majority ,well it doesn't take effect until the Twentieth Century gets under way."
When did Jesus teach the Watchtower doctrine? Not then, not now, not ever. It seems to me that the majority who professed christianity until the Jdubs came along partook by drinking and eating as commanded. What the Witnesses do not realise is that it's a very serious situation to disobey a direct command by God or, if you like, an order direct from heaven. It's even more serious for the Governing Body because they are the ones ordering the Witnesses not to partake unless they belong to that exclusive class. Which is total nonsense ,all followers of Christ should be his disciples .
