There is no practical way to reverse the ordination of women (a core facilitator of the slide.) This is one of the things that cannot be undone.
Count the loss and move to a biblical denomination.
Plan to stop membership slide... PREACH THE GOSPEL!!! That starts by firing Karl Marx.
I think one of the methodists bigger problems is they so fear dissent that they move ministers every 2 to 3 years.... So even if you get a good one, and they start to turn a church around.... POOF they are gone and replaced by someone else.....
All churches in the US are facing the same issues about membership and decline.... but the Methodists are making it doubly hard on themselves, by shifting leadership ever few years in local churches to make sure no one ever gets too loved and connected to their congregations.
The Methodist church lost me when it stop following the bible
