Alamo-Girl, I know you have studied St. Justin Martyr. I came across an insight in Voegelin recently that I thought you'd find interesting. Voegelin observed that Justin considered Christianity the "fulfillment" of classical metaphysics. As you know, Justin resonated most strongly with Platonic thought in particular. Voegelin writes:
By absorbing the life of reason in the form of Hellenistic philosophy, the gospel of the early ekklesia tou theou [i.e., church of God] has become the Christianity of the church. If the community of the gospel had not entered the culture of the time by entering its life of reason, it would have remained an obscure sect and probably disappeared from history.... In the conception of Justin the Martyr (d. ca. 165), gospel and philosophy do not face the thinker with a choice of alternatives, nor are they complementary aspects of truth which the thinker would have to weld into the complete truth; in his conception, the Logos of the gospel is rather the same Word of the same God as the logos spermatikos of philosophy, but at a later state of its manifestation in history. The Logos has been operative in the world from its creation; all men who have lived according to reason, whether Greeks (Heraclitus, Socrates, Plato) or barbarians (Abraham, Elias), have in a sense been Christians. Hence, Chrisitianity is not an alternative to philosophy, it is philosophy itself in its state of perfection; the history of the Logos comes to its fulfillment through the incarnation of the Word in Christ. To Justin, the difference between gospel and philosophy is a matter of successive stages in the history of reason. ("The Gospel and Culture," The Collected Works of Eric Voegelin, Vol. 12, p. 173.)
