This congregation has been one intent upon and vigorous in mission and outreach throughout its history. Its mother church, Rock, suffering loss of members considered closing its doors, and was without a pastor for fifty years (1906-1956). Through the efforts of members of this daughter Church the ministry of Rock Church was reactivated in 1956. This congregation had also been instrumental in helping to establish the Second Presbyterian Church in 1947 through beginning an outpost Sunday School in the Mathews Mill Village, which was organized as a congregation in 1948. Its name was later changed to Fraser Church. The growth of the city prompted the Presbytery of South Carolina to purchase land in 1968 on the northern side of the city for future development. Planning and surveys were conducted, and meetings of interested people were held. With a strong contingent from the membership of the First Presbyterian Church forming the largest nucleus, the Westminster Church congregation was organized in 1981.
The staffs of the First Presbyterian Church have contributed to its mission throughout the years. Many dedicated Associate Ministers, D.C.E.s, musicians, secretaries, interns, and custodians have added to the rich history of sharing and caring. Officers and committees who have given unselfishly of their time and talents have supported them. The congregation has been benevolent minded in sharing its wealth, monetarily and leadership wise, with needs and people far beyond its geographic and cultural surroundings. Such causes have included: child care and outreach within the community, support of denominational institutions and programs in this nation and around the world, mission trips by members to points of service wherever there is need, and a continuing expansion in the current day to respond to areas of hurt and concern.
