2 (at least, I haven’t really gone too deep down this rabbit hole) of the founders sons broke away and formed their own church, it got a decent amount of attention a few years back for doing some mass wedding thing with ar15s, as well as rifle blessing ceremonies. A few of the members of that church including the son who founded it were involved in 1/6, and the other one is the owner of Kahr firearms.

Again, they’re a breakaway sect, not the main Moonie church, so there’s surely some important ideological differences, but there are 2 guys who were raised by their founder, and the one was considered to be in line to take the whole thing over before having a falling out with his mom and deciding to make their own crazy cult instead, so you kind of have to wonder if these 2 nuts actually fell all that far from the tree.
