The overall position of the Church is that even cultures ignorant of Christ have a correct religious instinct written in their heart. We should not be surprised if we find elements of revealed wisdom discovered independently by cultures otherwise unenlightened.
The pagan neo-Platonists, through their study of the pagan Plato, arrived at some very high-level abstractions; the Church fathers took those abstractions and personalized them (using the context of the Bible). I'm not sure who's enlightened there and who's not.
The light is that of Christ. High-level abstractions are an impressive thing but light it ain't.
