Great post and discussion here!
My take: I love everything Elle writes about Humanism, but that all falls short of what Religion provides.
To paraphrase the great mythologist Joseph Campbell, Myth (or "Religion", we can say here) has several purposes. One is to tell us How to Live. Humanism as Elle describes it does that beautifully. But Myth also tells the human community Where We Come From. Where We're Going, and Why We're Here.
Secular Humanism just doesn't have those answers. Nor does Science. From all I can tell, if you peer deeply enough into Cosmology, Neuroscience, or Physics, the answers to those questions is always, "We don't know." or "Science can't answer that." So those of us who care about answering those questions must look again to Religion or Myth.
