This is also from the most recent issue of St Francis Magazine, which has some tantalizing articles. The Great Experiment was the primary missionary effort to the Muslim world for over two centuries and in this book review its main idea is outlined. I have read the book and it is quite good. If you don't feel like reading the entire book at least check out the book review over at SFM.
Anyway, a quote from Miller's review of Pikkert's book "Protestant Missionaries in the Middle East":
His main target is the so-called Great Experiment. When Protestant missionaries arrived in the area in the early 1800’s they soon decided that direct evangelization of local Muslims was too dangerous and difficult; thus was born the Great Experiment, whereby missionaries would revive what they saw as the moribund churches of the land—whether Maronite, Armenian, Greek Orthodox, Coptic, or what have you. These churches would be resurrected in the image of Western Protestant evangelicalism with all its iconoclastic and individualistic trappings. In other words, they were largely ambassadors of their culture—even to the other Christians. So schools, orphanages, clinics, printing presses and hospitals were all established, mostly with the aim of reviving the Christian communities. Pikkert argues that this behavior was suspicious to the local rulers, making their communities highly visible when they had managed to survive over the centuries largely by not being auspicious. Consequentially the various genocides and mass emigrations from the Middle East and Asia Minor over the centuries can be attributed, at least in part, to this misguided Great Experiment.
Not only that, the Great Experiment quite clearly did not work. While it did result eventually in the founding of Protestant churches composed mostly of OBP’s (Orthodox-background Protestants), it should not be surprising to anyone that even these Westernized Christians had little interest after centuries of mistrust and isolation in suddenly flinging wide the gates of the churches to Turkish and Arab Muslims converts.
