I think I know what you mean holmes. Your assessment is quite good but reference to the earliest texts is not likely to solve your mystery. There is much that we will never understand of them:
Vague words. Mysterious metaphors. Elusive idiomatic expressions. Allusions to other literature, now lost. Errors in translation. Errors in copying. Purposeful alterations. And things which simply cannot be translated into a flow of modern thought. Beauty which will never be accessible to the masses. Embedded yet irretrievable factoids which might lead to a better understanding of the ancient mind.
Most of these difficulties will be discounted or denied by "shepherds" of the modern "flock" but to me represent a deadly blow to hopes of discovering "God's own truth" therein.
Theologies purportedly built upon the Bible cannot endure the kind of piercing intellect which you bring to bear upon them. Theology is for the gods to impose upon ignorant masses of fleece bearing manimals and their innocent cannon-fodder whelps. There are gods and there are men. Let us, therefore, be godlike that we may be served by men.(let's make that
women, in my case).
P.S. - I know your question is serious and sincere but this quest goes better with a modicum of levity. You don't have to be crazy to seek god but if you are, you may find him sooner.
