This church, for the 25 years leading up to the separation, was pretty much Methodist in name only to be honest. The fact that they were the district's cash cow didn't hurt any, and the bishop and DS gave the senior pastor (who was there for all of that quarter century) a quite long leash to do whatever he wanted.
The senior pastor of the church in question has had a, shall we say, wide-ranging theological journey thanks to his father. His dad was a Southern Baptist pastor who was ousted for embracing speaking in tongues, etc. in the 70s. After his ouster, he joined forces with an evangelistic ministry to eastern Europe. Somewhere in there, he felt the Lord telling him to "return home", namely the Methodist Church where he was raised. (Obviously the Lord has since told him to leave "home" again...)
The son followed him through that journey and wound up in Methodism, neck deep in that "quite small charismatic wing". The main presenting issue in the split wasn't LGBT rights (though they are against ordaining or marrying the same-sex attracted), but pastoral succession. The pastor wanted the rights to name who his successor would be, as well as keeping his present staff.
