The question, is, what is the integrity of the story itself? Is it true to its intended purpose?"

Regrettably, Joe, I don't think that it is true to its intended purpose because that purpose
is never clear but subject to a variety of different interpretations that often are the roots
of violence, authoritarian domination and discord.

I think the term "truth" needs to be clarified. What is true may not necessarily be what we would consider physically real but maybe an idea that has some wisdom attached to it as Joseph Campbell has pointed out. But physical truths are the province of empirically proven scientific "Theorums". Evolution and the laws of gravity are scientifically true.

Joe, there is no arguing with your belief as long as we can agree that that's all it is,
a belief. No evidential proof is required. As to the Virgin Birth, this is an unfortunate
denigration of sex in my opinion. It also encompasses the theory of the "fall of man".
Sex as sin is in itself a kind of to, use a biblical term, an abomination. It also guides the Catholic Church's policy of not allowing priests to marry which has resulted in the
awful abuse of young boys.

Truth as Colbert has said can result in "truthiness". Just as facts become factoids.

BTW, Sugarfoot Jack, there are plenty of "brave" scientists out there and the new theories or scientific "Theorums" are not going to come from theology. There is however as you point out a question as to whether mankind is adaptable enough to survive. War has become mankind's specialization.

Theology historically has promoted war. Crusades are part of almost every generation.
Constantine, John Bull, and even up to today where we have General's Boykin and others
who want to Christianize the military. The Mid-east crisis, (and some will disagree on this point) has to do with religious differences between Islam and Jew. The Palestinians were referred to in early days as the Philistines. Today's Israeli rabbis have more to say about where Israel is headed than they should. Religion still draws blood.
