If we all gave all our goods to the poor, the church would fall apart. If we all hated our father and mother, as Jesus told us to, there'd be an end of the church's emphasis on the family as being the one important thing holding the whole society together. There are all sorts of ways in which the church's teachings contradict directly what Jesus says in the Gospel.
The crucifixion saved him [Jesus]. He never had to deal with the fact that the kingdom of God wasn't ever going to come. His disciples, of course, had to deal with it, and little by little they had to realize that it's a metaphorical thing. Well, that's not what Jesus meant. I'm fairly sure he meant it literally. But he must have been the most fascinating man.
He's [Jesus] the most fascinating character in history, really - the character who's made more difference to the world than anyone since him. I daresay that Muslims would say Muhammad was that character, but I think Jesus had a sort of 600-year start on him.
