The Reformed Mennonite Church was founded on May 30, 1812, in
Lancaster County, Pennsylvania, under the leadership of John Herr, the son of Francis Herr, a Mennonite who had been expelled from the church. Herr split from the main Mennonite Church on the premise that the Church leaders were deviating from the original teachings of
Menno Simons, and thus deviating from the true foundation of Jesus Christ. The new denomination retained the name "Mennonite" and identified itself as the only true Mennonite movement. Others, however, referred to followers of Herr as "New" Mennonites or "Herrites", and subsequently as "Reformed" Mennonites, which eventually became the denomination's official name. The Church reached its peak membership in the mid-nineteenth century, at which time it included up to 3,000 members in
Ontario and eight U.S. states. It has experienced two divisions in its nearly 200-year history. In 1917, three congregations located in
Huron,
Richland, and
Lucas counties in Ohio (along with a few members in Ontario) formed the New Reformed Mennonite Church under the leadership of
Minister John Miller. The cause for the split was disagreement over whether funerals should be held in cooperation with non-Reformed Mennonite ministers and over the Church's support of the
American Red Cross during the
First World War. The second split occurred in 1975 under Minister Willis Weaver, who organized the United Mennonite Church. In 1987, the group had 17 members located in
Lancaster County in Pennsylvania. ==Practices==
