Universal Atonement
If Methodist numbers are already shrinking with that doctrine why will a schism cause that to change?

In Presbyterian circles, the conservative PCA, originally a group of mostly Southern congregations, left the liberal PCUSA 47 years ago. it started out with 41,000 members and 260 congregations. As of 2018, the PCA has over 1,900 congregations and 395,000 members. Counting in other, smaller conservative Presbyterian denominations, there are probably close to a half million members, numbers that begin to approach those of the shrinking PCUSA. I would imagine a conservative Methodist body would have similar outcomes.
