pistolpete,
What is a plausible scenario that would cause tens of thousands of hard-core orthodox Jews to stop making Saturday their day of rest and worship and change it to Sunday... right in their holy city of Jerusalem? And, be willing to suffer shunning and their own death to do so?
"Deluded"? I'm sorry, but your one-word answer doesn't sound convincing
Do you know how many WOMEN, CHILDREN, are willing to strap a bomb on themselves and blow themselves up along with the infidels because they have FAITH they are doing the right thing.
You are making my point here. There is a huge religious, societal, familial, and social construct apparatus that makes it possible to understand how some muslims could get to the point that you describe.
Where was all that for Jews? Indeed they had all that, but it was all for making Saturday their holy-day. Then, with ABSOLUTELY NONE OF THAT in place, suddenly tens of thousands of orthodox Jews make Sunday their day of worship in honor of Jesus resurrection.
Your answer just isn't plausible.
