erm I am not sure
established churches were all the rage in the 1600s.
The Church of Wales, I think in 1906, was a sort of branch of the Church of ENgland and the low church Welsh (i.e. ALL) wanted to do away with it [disestablish it]. But the curates who were living off it, and all the high church men in Wales (i.e.no-one) didnt want to disestablish it.
SO that lot were antidisestablishment, and the persons were antidisestablishmentarians
Lloyd George gets mixed up with all this.
Yeah as you can see,nothing to do with theological controversies in the 1600s
