What Dowd is presenting is a "marriage" between science and religion. In this perspective, science is understood as God's "public relevation", which should be sought and cherished by believers and nonbelievers alike. Religiosity is acknowledged as part of Human Nature inducing personal experiences which should be turned into peace- and meaningful forms of engagement. To Dowd, the Universe unfolding through billions of years is a sacred "Great Story", i.e. showing that all living beings are formed out of stardust. To Dowd, the grand evolution of ever-new live is also telling us about the necessity of death - a fundamental truth he finds in Jesus' way, too.
Here I found the (self-confident and humourus) book-trailer:
Classic topics of religious traditions gain new aspects from this evolutionary perspective: For example, the narrations about the Expulsion from Paradise and "Original Sin" are understood by Dowd as powerful symbols of a scientific relevations (that is here: evolutionary psychology): That we Homo Sapiens got brains whose structures evolved under very different circumstances, bestowing all of us with unique sets of "sinful" impulses as Greed, unfaithful Lust, Aggression etc. Evolutionary Spirituality would thus be understood as learning to cope with our Natural and Cultural heritage in order to be able to live in integrity. Dowd sincerely hopes to bridge the gaps leading to the infamous "Culture Wars" between scientific and religious strata during the last century. And from the perspective of the scientific study of religion, the personal reviews of TGFE in amazon.com are indeed very interesting!
From the background of my scientific field - empirical and biological studies in the evolution of human religiosity - I feel not inclined to judge theologies. But I might say that Dowd and Barlow are offering a refreshing new perspective to debates which have stagnated far too long. What's more, it might offer an alternative to fundamentalist creationism and Intelligent Design (as discussed in the clip below). Extreme people on either sides might resist the bridge-building-effort - but the rest of us might enjoy an (at least!) surprising and encouraging read!
