> You, I think, are seeing different religions with the same codes and calling them variations on the same theme.
Yes, that is basically correct. I also believe that many of the current religions originated from inspiration by one and the same God.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
