A.B. Simpson (pictured above) founded the Christian & Missionary Alliance, in 1877. Born 1843 in Cavendish, Prince Edward Island, Simpson became a superstar minister, one of the shit-hottest Presbyterian preachers in North America. The young man from Cavendish got such a name for himself that he was able to snag top-dog position at the Thirteenth Street Presbyterian Church in New York City. New York City! After just a couple years, Simpson grew disenchanted and quit to help impoverished immigrant communities instead.
No, the Alliance Academy (AA), the boarding school in Ecuador which I attended, was not like the one Boris Johnson went to. It could not have been more unlike Eton. We were not ultra-posh aristocrats, a short distance away from our ultra-posh families, destined to one day rule the world. No one envied us. No one would have switched places with us, not for all the money in the world. Yet when I say boarding school, Eton is what people seem usually to want to see.
I suppose that this has suited me. Mostly, I have allowed, and even encouraged, my friends to imagine that my upbringing, although unusual, was still largely in keeping with the English public school tradition—proper and well within normal social bounds. I’ve found overall that people don’t want to know, anyway. Even if you try to tell them, they keep not wanting to hear it. Nobody wants to try and imagine what it was like. Which, I get it: empathy is not my generation’s strong suit.
Thoroughbreds (Cory Finley, Dir., 2017), a film about a young woman who conceives a plot to murder her step-father to prevent him from sending her away to a correctional boarding school against her will, indicates maybe that subsequent generations get the horror of it all much more keenly. What's a non-posh boarding school? A prison—for children.
I received my education inside a guarded compound at a facility in a foreign country with no oversight from any national government. Where communication with our parents was prohibited, and outgoing mail was censored. It is absolutely impressive that the Christian & Missionary Alliance got away with it for so long, and that they have managed to escape any repercussion of consequence. I imagine that most of its members and adherents don’t know, and don't care to. As Charles Edwards Jones notes the most remarkable thing about the Christian & Missionary Alliance is its adaptability, that the denomination “has provided for its people a bridge over nearly every rift in the revivalistic evangelicalism of the past century.” The C&MA knows how to survive: since the 1880s, it has shown the savvy to manoeuvre and thrive amidst the theological feuding that has claimed most of its kind. One massive, decades-long, child abuse scheme, more or less, please—it’ll take a lot more than that to slow the Alliance down.
Anya Taylor-Joy (pictured) plays Lily in the semi-comic, and actually not very good except for the boarding school revenge fantasy part of it, supposedly sort of indie film Thoroughbreds from 2017.
