RE: It's a the Ben and Lauren Show Episode 45
I find that going with the traditional calendar seems to be the best way. Here is a couple of reasons that make sense to me. First off if we are to drive Judah to jealousy how can we do that if...that group is doing the feast that day and then another group is doing it another day then there is still another group doing it another day. Judah would just look at that and see the confusion and would want no part of that.
The other reason is...
Genesis 49:10 The scepter shall not depart from Judah,
Nor a lawgiver from between his feet,
Until Shiloh comes;
And to Him shall be the obedience of the people.
This tells me that even if Judah is not doing it perfectly the way God wants it says here that until the Messiah comes Judah is the lawgiver and we are to do what Judah does. A Jewish council came up with the current calendar. Since Judah has not changed it why right do Gentiles have to change the calendar? Now am I saying that Judah has it 100% correct? Nope...but until Yeshua comes back I'm sticking with Judah!
I agree with your points and I can understand the desire to witness to the Jewish people and to acknowledge Judah as the lawgiver.
Calendar debates have been ongoing for centuries and I find it fascinating that it's even discussed in ancient Christian writings. Reading the Constitutions of the Holy Apostles, it talks about not computing the calendar yourself, but keeping the moedim with "your brethren of the circumcision".
