/lit/ - Literature

Just out of curiosity, where would you guys consider Oriental Christianity on the spectrum of religions? Oriental Orthodoxy, Eastern Orthodoxy, and Eastern Catholicism all have ancient pre-Islamic traditions in the middle east and parts India that according to Guenon, are still in contact with the primordial tradition. They were not brought there by European missionaries. I feel like many people completely cast them out of the picture. I would be interested in learning more about their relations between the different traditions and their spiritual practices. It seems like there is a huge lack of literature in English on them, though. Please help me out friends :))
