Located in Smithville, Ohio, Oak Grove Mennonite Church is an historical church that has made a significant contribution to the larger Mennonite denomination, currently pastored by Seth Miller.
Bishop Yoder's main contribution to Oak Grove was his progressive attitude toward Amish doctrine.
Diener Versammlungen, from 1862–1878 were denominational meetings in which Amish ministers met to discuss changes in the Ordnung.
After 1863, many of the conservative ministers removed themselves from the meeting, and as such, John K. Yoder led toward progress, forming an "orphan congregation" which became Amish-Mennonite.
