I don't know of one that has gone thoroughly liberal that has been reclaimed. The S. Bapts reclaimed from a moderateness.
The UMC is creaking back in the right direction.
Our children are not injured because the conservative movement has gotten very organized. They even have their own publishing: periodicals, Sunday School literature; and their own women's association; and even their own mission sending agency.
Long years of hard work have gone into reclaiming the UMC. Many long years remain.
We will not have victory until we reclaim our seminaries, boards, and agencies.
You may be interested in the link below to the Alliance of Confessing Evangelicals. There is a signficant UMC involvement in that organization.
