About Dr. Rankin
Raised in a Southern Presbyterian home with shared roots in the Moravian ministry, Dr. Rankin graduated summa cum laude from Clemson University in Ceramic Engineering, where he was founding president of the campus Inter-Varsity Christian Fellowship. After working for DuPont at the Savannah River Laboratory and Ph.D. studies in Materials Science at the Massachusetts Institutes of Technology, the Lord redirected Duncan’s steps from a successful career in the sciences towards the Gospel ministry in the Presbyterian Church in America (PCA). After completing his Master of Divinity studies at Covenant Theological Seminary and Reformed Theological Seminary (RTS) in Jackson, Mississippi, he took his Ph.D. at the New College of the University of Edinburgh by writing on “Carnal Union with Christ in the Theology of T.F. Torrance.”
Appointed to the Department of Systematic Theology at RTS-Jackson in 1993, Duncan served 10 years full time, teaching courses in dogmatic and historical theology. Active on the Theology and Strategy Working Group of the Lausanne Committee for World Evangelization, Duncan was also a recipient of a John Templeton Foundation 1999 Science and Religion Course Prize and taught a course in Science and Theology at RTS. At the Millennium, the Rankin family escaped the ravages of Y2K by sojourning in the quiet Scottish Highland village of Muir of Ord, before Duncan served as guest minister for Dr. David Robertson at St. Peter’s Free Church of Scotland in Dundee, home of the historic pulpit of Rev. Robert Murray M’Cheyne and current home of the SOLAS Ministry.
Since 2003, Duncan has pastored churches in Mississippi, Tennessee, and Georgia before finally making it to Texas as fast as he could, where he now joyfully serves on the staff of Christ Church (PCA), Katy, Texas. In addition to service at RTS, Duncan is also a member of the Board of Directors for GRACE—a Godly Response to Abuse in the Christian Environment and a Visiting Professor for Ligonier Ministries’ Reformation Bible College, Sanford, Florida. He and his wife Shirley have three fine children and love living in the Houston area!
