That seems to be what Joel Zartman is driving at.

My point is not that Athanasius was not a Christian. My point is that committed and robust 4th century Christianity found the categories of Platonism extremely congenial, greatly so. It was how they made sense of things. I don’t think we can understand these Christians without appreciating Platonism better than (in my opinion) many do (e.g. Thomas Weinandy). I certainly think the only crowd that stands to gain [from] the outdated notion that Greek philosophy corrupted Christian simplicity is that served by a more ambiguous and doctrinally impoverished religion.
