Ok - here is an interesting one for ya'll. Just throwing it out there for your thoughts.
The "Lords Evening Meal" is always celebrated on the day that corresponds to Nissan 14. My parents are still JW's and (as ya'll know) the Memorial service is the "most important meeting of the year" - they literally cry if I don't go. So I'm thinking - I'll show my mother and father honor by going - I can fake it through one meeting right?! (besides - noone will talk to me since I'm shunned and I'll get out early)
Anyways - So I go to the Jewish calendar and mark down Nissan 14th (Wednesday - today!!) in advance so I have that day free. My mom gives me an invitation to the memorial last week - guess what....It's on Thursday night (no way!!). So I say "hey - what's up??? Nissan 14th is on Wednesday...I know because I looked it up in advance (yadda yadda yadda)" This starts a whole discussion...the conclusion of which...........here goes.................
According to a number of Watchtower Articles explaining how they calculate Nissan 14th - the Jews are not always correct in how they calculate their own calendar so you can only know what date Nissan 14th is on by the Governing Body.
Wow...pretty amazing hu?! Needless to say - I decided it was just too exhausting and I'm not going ;) However, I celebrated on my own (tonight!!) with prayer of thanks, unleavened bread & a little wine - and I didn't even have to get shunned to do it!
