The problem is that the Bible we have today is as garbled a mess as all of the other texts which survive to us from that era. More so, in fact, because nobody ever argued much about which chapters to put in the Iliad or the De Bello Gallico. Bible study is really the attempt to reconstruct what it was all supposed to have meant originally - a heroic, if tragic, endeavor.
The history of Christianity is in many ways the history of our attempts to work around this problem. The earliest Greeks thought "perhaps we can understand Christ's teachings in terms of the philosophy we were already familiar with". The medieval Church thought "perhaps through diligent and painstaking intellectual discourse, we can try to figure much of what was lost for ourselves." The Protestant tradition began with a brave stab at trusting the surviving Gospels alone, and trying to make as much literal sense from them as possible. The Nestorians, Manicheans, Cathars, and so on had even weirder ideas.
Methinks your research on the issue is very inadequate and lopsided.
