St. Basil the Great advised young monks to use Greek philosophy as a bee uses the flower. Take only the "honey," ---- the truth --- which God has planted in the world to prepare men for the Coming of the Lord. (
from here)
I remember reading somewhere that greek philosophy was a necessary vehicle for the gospel to be properly understood. In a sense the philosophers were to the Greeks what the Old Testament was to the Jews. In at least one of the churches in the monasteries of Mount Athos, they have the greek philosophers depicted in the frescoes on the walls along with the saints (though not depicted as deified, unlike the saints). The Apostle John made use of them (In the beginning was the Word) as did the Apostle Paul so why aren't they considered as being Neoplatonic?
I hope they were helpful comments.
