You are falling into the materialist trap. Materialism asserts that matter is the fundamental constituent of reality. This view is not reconcilable with the idea of a soul or a mind. Now, the problem with dualism is that one cannot possibly demonstrate that non-physical can effect physical in any quantifiable way. So, some form of monism necessarily entails: Either materialism or idealism.
Now, you may notice that the only way in which you can understand the world is that first you perceive something outside of yourself and then you form ideas about what you perceive (to conceive). The question then follows: How can I possibly prove that matter exists fundamentally (without me perceiving it)? How can I separate the rational/mental nature of the world from the world itself and thus posit the existence of matter?
One cannot: Matter is an unprovable assertion. And yet, there is an objectivity to this world. This objectivity poses a problem to solipsism (How can I know anything exists other than my own mind?) and so one can rationally conclude that there is a mind greater than my own which provides objectivity to my experience of the world. In noticing the continuity of the world and its unified laws of physics, etc. one must conclude that this greater mind is single and one (As Augustine points out). This greater mind is a necessary being: God.
If you insist that matter exists outside of being an emergent property of the fundamental information of the universe, then you would be wrong in light of the latest theorizing in Quantum Gravity. If you think that idealistic notions are specifically Greek, then you have not read Jewish philosophy (Maimonides, the Zohar, etc.). As a note, the Bible is not philosophy, it is revelation; so you should not propose a false dichotomy. I believe Aquinas explains the relationship between philosophy and scripture quite aptly, if you are interested. Cheers.
