Some (small) food for thought:
Much of orthodox Christian theology owes its success to the work of African and Asia-minor thinkers. Regarding the former, one need look no further than the North African theologians. Augustine, Tertullian and Cyprian are just a handful (and what a handful!). One could also throw in there for good measure Origen (from Alexandria, Egypt) and Athanasius (Also Egyptian. Fun fact: he was derisively nick-named the “black dwarf” because of his physical appearance). And the Asia-minor thinkers? Look no further than the Cappadocian Fathers (Basil the Great, Gregory of Nyssa, and Gregory of Nanzianzus), residents of what is now Turkey and undisputably important theologians.
All of the thinkers mentioned above are powerhouses who contributed enormously both to Orthodox theology and Western thought generally. And none of them are European. Before Barth, Tillich, Multmann, etc. there were the African and Asian thinkers who laid the foundation for centuries to come. Granted, they were themselves part of the Roman Empire which traded in both Roman and Greek ideas; however, it is (to my mind, at least) an important fact of history for present cultures whose own past prejudices looked down upon the intelligence of African, Asian, and other cultures. There is, I think, a significant and tragic irony in the midst of it all. Modern Western cultures (i paint broadly here, forgive me) who until quite recently believed in scientific evidence that pointed away from the intelligence of African peoples were themselves indebted to African thinkers and people like the “black dwarf.”
