Polytheism does not in fact give us the idea of a Creator, but only of a myriad of contending forces, pushing mankind from pillar to post. The God of Abraham enters history as a compelling voice that guides a single man and his family for many years and leads them to Egypt and then out of it, revealing himself more powerful than all the gods of the great civilization of Egypt, including with the god-king of Egypt. Israel, the first born of the Lord is freed through the destruction of the First-born of Pharoah. Then he makes covenant with Israel as he has made covenant with Abraham. Like Plato, but by a very different process, Israel comes to believe, through a process of rejection of the many gods, to believe in one. Josephus was convinced that Plato was familiar with Moses.
Modernists like Jews and Christians, note how Judaism and Platonism came together, Jerusalem and Athens, faith and reason, came together in Judaism and Christianity. But while Christianity saw Platonism, or neo-Platonism as kindred in Spirit, yet the Christians were careful to avoid the Platonists tight embrace. For Christianity is rooted in concrete experience not the abstract. What it did provide was the kind of certainly that the world really means something, that it was an intelligent and knowable things, however confusing and unintlelligibe it might seem at times. It was on this foundation that modern science was built, avoiding the skepticism that kept the Greeks from pulling it altogether, even though they had all the elements of physics sand math they needed.
Well-put. It's an important distinction to stress.
