Yes, the Sadducees denied a resurrection of any kind. That's kind of
sad, you see? [
That's how I always remember the difference between the Sadducees and Pharisees. LOL!]
That's also why they ignorantly challenged Jesus about the hypothetical husband who died and his widow married the brother, and then he died and she married the other brother and on and on seven times. They really thought they had him trapped when they asked, if there is a resurrection, then which brother will be her husband?
I've always loved Jesus' answer.
"You are mistaken because you don't know the scripture." We should all look at ourselves through the lens of THAT verse!
Speaking of things Jesus Christ said, whatever or wherever you believe hell is, he said it is eternal. There is no annihilation.
I don't take that lightly or with glee. Neither does God.
