美南长老会
An attempt to reunite the United Presbyterian Church in the USA with the Presbyterian Church in the United States in the late 1950s failed when the latter church was unwilling to accept ecclesiastical centralization. In the meantime, a conservative group broke away from the Presbyterian Church in the United States in 1973, mainly over the issues of women's ordination and a perceived drift toward theological liberalism. This group formed the Presbyterian Church in America (PCA).
