this isnt my name said:
So how do you feel about the offering animals to god stuff ? I am assuming it was important until it was banned. (who banned it btw ?)
Also I remember reading before that some holiday you guys celibrate was actually a cover up for you siding with the Romans against the Greeks, then the Romans screwed you over is that true ?
The animal sacrifices were preformed during the old testiment times, up until the destruction of the second temple around 70 AD. Since then, no more scrifices were done. In theory, if a 3rd temple is ever built, the sacrifices would start again, though I doubt it will ever happen.
As for the Romans and the Greeks, I think you were misinformed. Hannukka is in celebration of the successful rebellion against the Greeks and the miracle of the oil lamp (it lasted 7 days longer than it should've). We also have a small holiday called Lag Ba'Omer, usually in May, during which we make bonfires. It's a way of marking the failed rebellion which happened against the Romans a long time down the line from the rebellion against the Greeks (I think it was more than a century, but I'm not sure).
