Officers
The Presbyterian Church in America (PCA) recognizes two kinds of biblically sanctioned church officers, or ordained leaders, continuing beyond the apostolic age of the church. Chapter 7 paragraph 2 of the PCA’s Book of Church Order defines these kinds, or classes, of ecclesiastical office, “The ordinary and perpetual classes of office in the Church are elders and deacons. Within the class of elder are the two orders of teaching and ruling elders. The elders jointly have the government and spiritual oversight of the Church, including teaching. Only those elders who are specially gifted, called and trained by God to preach may serve as teaching elders. The office of deacon is not one of rule, but rather of service both to the physical and spiritual needs of the people. In accord with Scripture, these offices are open to men only.”
As a mission work, Antioch Presbyterian Church is governed and overseen by a provisional session of elders serving as a commission of Calvary Presbytery. The seven men appointed to the provisional session are active elders within the bounds of Calvary Presbytery, and they serve “above-and-beyond” at Antioch. They include:
- Dr. Chipley Bennett, PhD – Ruling Elder, Providence Presbyterian Church
- Dr. E. Todd Buchner, DMin – Teaching Elder, Reidville Presbyterian Church
- Pastor Zachary Groff – Teaching Elder, Antioch Presbyterian Church; Pastor & Clerk of the Provisional Session of Antioch Presbyterian Church
- Mr. Richard Hollifield – Ruling Elder, Roebuck Presbyterian Church
- Mr. William Johnson – Ruling Elder, Woodruff Road Presbyterian Church
- Dr. Joseph A. Pipa, Jr., PhD, DD – Professor of Systematic & Applied Theology, President Emeritus, Greenville Presbyterian Theological Seminary; Pastor & Moderator of the Provisional Session of Antioch Presbyterian Church
- Mr. Theodore “Terry” Richards – Ruling Elder, Fellowship Presbyterian Church
At this time, Antioch Presbyterian Church does not yet have a diaconate.
