We went through this onslaught of heresy early on in the dense Boston-to-DC conferences. My southern Methodist relatives' conferences took longer, but now are all secular politicized, as well.
The church is not a building or a denomination or even a congregation. It is the unbroken thread of belief in the gospel of Jesus Christ. Once that goes and there's little hope of a congregation making a recovery, it's time to shake the dust off your feet and go. The prophet is honored everywhere except his own home town and among his own people. The Son of Man has no place to lay His head.
It was wrenching, but finally I did leave the church of many generations of Methodists in my family and sought another, which took much research and some years, including divesting myself of prejudices, suspicions and snobbery towards other denominatons.
God took me on a winding journey through several denominations and half-a-dozen dedicated prayer groups that met regularly, as well as participation in the wonderful Community Bible Study program. At last I found a Bible-believing church that is right for me.
Bible-affirming is the must-have component; after that, the way the church is organized, the mission statement of the denomination (or independent organization), and whether the local church has ministries and groups in which you can grow.
I think I’d be ok with a Wesleyan or Lutheran MS congregation.
The problem is that none in my area has the ministries/groups Im looking for.
I credit the UMCs youth programs with keeping me from going any further from God than I did. I want that foundation for my kids.
