Well, sort of. If we interpret Harris's "facts" in the narrow sense of what can be empirically investigated with current scientific methods, then I am in fair agreement with his position as stated above. As a scientist myself, I cannot stomach the poison brew of fundamentalism, but as someone who knows the reality of God as revealed in Christ, I have never been a fan of weak tea either; if I can't have it good and strong I'd rather join Harris and his friends in drinking the plain water of atheism.
But fortunately, those are not the only drinks available at the bar of religion. We are not stuck with a choice between the miracle-working fantasy Jesus implied by a literal interpretation of the four Gospels and the purely human "Jesus lite" philosopher, moralist, prophet and/or reformer of the tea drinkers. There is a third option, the original one, who appears in all of the parts of the New Testament that predate or are uninfluenced by Mark's invention of the "Jesus of Nazareth" figure: that is, pretty much all of it other than the Gospels and Acts. In terms of beverages, that Jesus could be described, without too much irreverence I hope, as "wholly Spirit". I am currently reading Earl Doherty's "Jesus: neither God nor Man", which does a wonderful job of how this figure was understood by Paul and the other epistle writers to have come down from the highest heaven and been crucified and resurrected in a "sub-lunar" demon-infested spiritual realm whose existence only makes sense within the (to us) peculiar Middle Platonist world view that was prevalent at the time.
The discomfort that many Christians feel on first hearing of a purely spiritual Jesus is understandable. If there was no incarnation, no crucifixion at Calvary, no resurrection of a physical body from a tomb just outside Jerusalem, then we feel somehow let down and cheated. Is this not "Jesus lite" in another sense, the ultimate retreat of the God of the gaps before the onward march of materialism, the final defeat in Harris's zero-sum game, resulting only in an ignominious Dunkirk-like evacuation of our faith from the entire material realm?
Such worries highlight an important issue about our real beliefs. The prevalent world view of our time is what Ken Wilber calls Flatland: the complete denial of the dimension of height and depth, of anything beyond what he calls the "monological gaze" which can only see the surfaces of things. A materialism that totally rejects the reality of spirit, that says that only what we can see, touch and scientifically measure is truly real.
Despite protestations to the contrary, many Christians have in practice been hoodwinked by this absurdity as thoroughly as any atheist. Fundamentalism therefore promulgates a Jesus with a firm foothold in the material world and asserts that whatever scientific orthodoxy might have to say about him is just wrong, while liberalism takes the other tack and discards the miraculous elements to arrive at a Jesus acceptable to the scientific mind. Both are equally materialistic, both are equally wrong, and the contempt that Harris and his friends feel for both camps is hard to argue with.
What it comes down to is this. Do we, or do we not, believe what the early New Testament writers took for granted, that spirit is just as real as matter, if not more so?
I don't think we all have to become Middle Platonists to accept this formulation of Christianity. Scientific developments from the time of Copernicus onwards have made that impossible anyway. At the time the New Testament was written, the classical world was undergoing a shift away from an ancient form of religion in which spiritual realities, packaged, as they perhaps always must be, as myth, were located "back then", in the distant past. The ancient gods were losing their power; that's why Socrates was accused of atheism. The new, Platonic world view located spiritual things "up there", in heavenly realms above the earth, and sometimes "down there" in hellish ones below it. For whatever reason, that made much more sense to people at the time.
A similar shift is taking place today, and has been for several centuries. "Back then" is no longer available to us, because of Darwin as well as Plato, and now neither is "up there" because of Copernicus. Guided by Jung among others, many people now locate spirit "in here", within, or through, the human unconscious. Maybe they're right; maybe in another few centuries another metaphor will be in use; maybe we will outgrow such metaphors altogether. I don't think it matters that much. The important thing is that spirit should be known and experienced, not just believed, to be real. Then we can appreciate and celebrate what science shows us within the material domain, while being aware of its limitations. Science, after all, is a matter of exercising our rational faculties, and there is no reason at all to assume that rationality is capable of grasping the whole of reality. That's why myth and mysticism are essential aspects of who we are.
If you really know that spirit is real and God is real, then there is no reason whatsoever to feel uncomfortable at the idea that Jesus of Nazareth (the conventional "historical Jesus") never existed, if that is where the evidence points, which it seems to me that it conclusively does. Rather, we can welcome what Harris, Doherty and other atheists are showing us, and use it as a means to reshaping and liberating our faith, even if they would curse us for doing so. "The end of faith" indeed, but in a teleological rather than a terminal sense.
