Sources are quite varied as to the early history of Mt. Olivet Methodist Church, but I believe it was established circa 1843, per the Liberty County Historical Society, and the present structure built in 1881. A bicentennial history of the South Georgia Conference of the United Methodist Church, published in 1984, posited that the congregation was established circa 1768-1770 as Pleasant Grove. My understanding is that Pleasant Grove was a satellite congregation of Midway, established in the early 1800s. Because of a plantation association, it catered more to its enslaved congregants, and as a result, its white members eventually established Mt. Olivet.
Stacy Ashmore Cole has done excellent research on the subject of the Pleasant Grove name and concluded: “There are several Pleasant Grove churches within the history of Liberty County…” including the “now-defunct Pleasant Grove Methodist Church that was an offshoot of the Midway Congregational Church. Founded in the early 1800’s, it was attended by both white and black – enslaved and free – members…The white membership of the church later founded the Mt. Olivet Methodist Church in Fleming, Liberty County, which still exists.”
I feel that this is the same Pleasant Grove referred to by Lillie Walthour Gillard in Liberty County: A Pictorial History: “A meeting house was erected on land between the North and South Newport rivers in 1806 and was named Pleasant Grove [possibly on Roswell King’s South Hampton plantation]. According to Dr. Stacy’s history of the Midway church, “Messrs. Bradwell, John Ashmore, Colonel Joseph Law and others held reading services every Sunday for the Negroes in that area. Later the Methodist circuit riders made it a station from which the Negroes benefited.”

This church is in remarkable condition considerint its build date of 1881.
