The church called its first full-time pastor, Rev. Matthew McGowan, in 1954. Under his direction, CMPC constructed its second building. During the next 33 years seven other men served as full-time pastors. CMPC joined the new Presbyterian Church in America (PCA) in 1973.
In 1981, a number of people were beginning to drive from Gainesville to Chestnut Mountain in order to be a part of a PCA church. Seeing a great opportunity, CMPC planted a daughter church, Westminster Presbyterian Church, in Gainesville.
