I don't find all Judeo Christian thought a "fail" unless you need it to be literally true to be beneficial!
What lessons do you learn about humanity and morality and human values from Greek myth, for instance, but is Zeus real? Is Heracles? Is anything in "The Odyssey" real?
Probably not, or it's a legend derived from some compilation and exaggeration of actual events affecting actual people. So is the Bible.
But, why do you think Greek myth or any myth is taught as part of classical education? Why is Judeo Christian thought, for that matter, because at some level it is?
Not only did it effect the way generations and generations of people acted and thought, it still is, for better or worse. But not all of that is bad.
Our law is somewhat based on some Judeo Christian concepts of justice and we believed God was just, and so must we be.
That is useful. It may not be at all true, but until some more factual and equally compelling reason to be just came along, it sufficed. I think we're moving a bit past relying so much on myth of that rather primitive age to base all of our social values on, as some of them are definitely no longer useful.
But, they do have some value because some of Judeo Christian thought is just basic to humanist thought anyway, it's just what we'd do if we treated each other ideally, anyway.
And we will replace old myth with newer, and more useful and relevent ones, because humans do that. We already are, actually. We need our myths, our heroes, our epic stories of good and evil. We just don't need to believe that we're quite as helpless in the face of nature anymore. Because we're a little less so than we were and we definitely understand nature a lot better than we did 2 or 3 thousand years ago.
