In a segment of the Sermon on the Mount, appearing in Matthew 5, Jesus is reported to have set six new teachings of his against six old Jewish teachings. The latter are introduced by such words as 'You have heard that it was said by them of old time' and the former by 'But I say unto you.'Since both the teachings of old time and Jesus' new teachings are predicated on the same profoundly mistaken views of human nature and of the world in general, it is unimportant for us here today to compare and contrast these teachings or to determine which is better or worse in some way or other. The point is that whether better or worse, in this way or that, both are lodged in an egregiously mistaken mythology -- but in a mythology of enormous importance for us, because it is one of the wellsprings of Western culture.
