Congratulations to Mark Koller on the completion of his comprehensive exams in doctoral studies in Historical Theology. The doctoral comprehensive examination committee consisted of Dr. Jonathon Beeke, Dr. Adriaan C. Neele, and Dr. Greg Salazar.

Mark’s research focuses on the writings of Samuel Rutherford (1600-1661) with a focus on “The Nature and Structure of the Church in the Ecclesiology of Samuel Rutherford”.

Mark served as the church planting pastor of the Dallas Reformed Presbyterian Church (RPCNA). The Reformed Presbyterians are the direct descendants of the Scottish Covenanters, a primary interest of Mark’s research. He is a major contributor and co-editor of the multi volume publication The Works of Samuel Rutherford.
