The first Methodist Church service in St. Marys was held at the Presbyterian Church in March 1873 and for over 22 years the Methodist congregations moved from location to location for church services. The Joshua Sykes family kept the cause of Methodism alive in St. Marys until 1895 when more formal services were held by sharing a minister from the Emporium circuit with St. Marys, Benzinger, Beechwood, More Hill, Howard and West Creek. These towns formed the new St. Marys charge until property was purchased in the present church location on N. St. Marys Street for the St. Marys Church alone. The church building was dedicated in November 1897 and it was completed in 1903, with an addition in 1923 of Asbury Hall and extensive renovations were done in 1957 and 1965. The mortgage was burned in 1963; showing the resolve of the congregation to complete a project both physically and financially. Over the years the house next to the church was purchased for the parsonage, the bell tower became unstable and was replaced with a spire, neighboring homes were purchased for parking and in 1979 a steel building was built to expand the services that the Methodist church was offering to their own congregation and the community of St. Marys. More recently projects that have been accomplished are the construction of a handicap entrance to the church enlarged the front foyer area and continually updating the various rooms in the church.

As the Church continued to grow, the congregation was outgrowing their present location, and the board began looking for land to expand their church and their community service. In 2008 over twelve acres were purchased on South Michael Road. Thus the beginning of the Greenlands Project.

The Greenlands Project is located on South Michael Road, in St. Marys, approximately 2 miles out of town.  The land is open to everyone in the community, including the St. Marys Methodist Church members, families and friends, community families and individuals, other congregations, charitable organizations, municipalities, community businesses and non-profit organizations. It offers thinking outside of the box by providing outdoor church services, programs, weddings, funeral dinners, family events and community programs. The project reaches far beyond the walls of a physical church building.
