The autonomy of the Korean church is partly the result of conscious missionary policies. For example, at the turn of the century the Presbyterians, who comprised the largest missionary body, adopted a program to foster self-propagation, self-government and self-support. This was the Nevius plan, named for John L. Nevius, the Presbyterian China missionary who devised it. It opened unheard-of opportunities for common people, women and men, to enjoy social and educational advancement through participation in the church. It spurred modernization through literacy programs and leadership training. It also emphasized rigid adherence to doctrine and strict rules for Christian behavior, which led to much hair-splitting later on.
