Just got a translation in the local language of this book.
WHY IS THIS NOT TRANSLATED INTO ENGLISH?!
It's made by a german lutheran that specialises in oriental christianity, and explains EVERYTHING about the history of christianity in the Middle East, from their rise and fall, to all the groups involved, to their psychology, to why those churches are so ethnic, corrupt and non-evangelising, to a direct account of the disappearance of Nestorian Gulf Christians.
Demolishes everything from western liberal "le muslims were so tolerant and advanced, omg!", to /pol/tarded extremes on the other side.
