Which would mean that Hope's idea that they had forgotten about the spiritual messiah thing is completely fallacious.
Well it is an idea. I don't know if it is fallacious or not. "Where there are two Jews, there are three opinions"; no doubt that has always been so. Today there are Jewish groups who believe the Messiah has been on earth and physically died, they are highly spiritual, believe in an afterlife and are preparing for Armageddon. Others, equally sophisticated, believe quite differently. The ancient stories and traditions have been handed down to each generation but, like many religious groups, they part company because different emphases are placed on the ancient teachings.
We'd really have to ask some Jewish people, a pity we don't have some posting on here, but I can guarantee we'd get several answers.
Christians place different emphases on Jewish teachings, some of which would be unrecognisable to Jewish people.
