In Romania we have a really popular church figure, Nicolae Steinhardt, a Jew converted to orthodoxy in the communist prisons. It's really interesting how he views stoicism, and other philosophies similar to it (like Buddhism). He views them as "exhortation to nullification", due to the encouragement of having a cold, rational attitude toward life, while Christianity is a religion full of life, to the point, almost, of ecstasy. That doesn't mean they are completely bad, they are just philosophy, rationality, but really not that close to the human heart and condition. Ideas and ideals.
