1 pointThat was the point ... even today people like Spong are taken as atheists as they do not have a literal belief. Did Spong and others start off with a literal belief? Is this metaphorical interpretation a post hoc belief? Was it for you? Personally I never had a literal Christian belief. Yes we all are to some degree indoctrinated in our beliefs ... I cannot choose to be a Buddhist at least not in this moment. But because of the new insights and better education fewer people have this desire for faith. It is difficult to be indoctrinated into faith when those around you are faithless. At university very few of my associates were religious and if they were it did not show. At work (in a science and engineering type world) there were fewer religious people so it was more difficult to pick up this religion meme. And finally they are not my points ... Those points were a distillation of what some religious scholars/investigators believe we can reliably ascribe to Jesus. There are a large handful. You can find the complete list here.
1 pointTom, the Catholic monk Thomas Merton once said that a "saint" is not so much one who has reached a certain level of sanctity, but more that they always see something to love in others.
