First Presbyterian Church members proudly boast having the oldest church building inside Grafton city limits. We believe with a deep history comes a steadfastness that withstands the test of time. In the winter of 1855, Presbyterians in the Fetterman community gathered in their homes under the leadership of Rev. S.H. McDonald of Fairmont. From there, services were moved to the Baltimore and Ohio Carpenter Shop in Fetterman for the remainder of Winter and Spring.
In 1865 the congregation was notified the old carpenter shop was to be razed. The congregation quickly purchased two lots on the corners of Washington and Mackin Alley. The church was built and finished debt-free on October 6, 1867. In 1872 the Rev. James H. Flanagan was installed as full-time pastor serving the church for thirty-three years until his retirement in 1905.
In 1970, following the death of Pastor J. Henry Thorhauer, attempts to obtain needed financial assistance from the Presbytery and Synod were unsuccessful. This opened the way for discussion with St. Paul's Lutheran Church which led to the Federation of the two congregations in 1972.
The Church of the Covenant today worships inside the original First Presbyterian Church built in 1867.
