Greg Bahnsen (1948-1995) was the scholar in residence at The Southern California Center for Christian Studies where he taught
Apologetics from a distinctly
Reformed perspective. Bahnsen followed the lead of his mentor
Cornelius Van Til and reasoned that, apart from the Christian faith, the unbeliever cannot account for his knowledge. Bahnsen earned a B.A. in Philosophy from Westmont College, his M.Div and ThM from Westminster Theological
Seminary (1973), and a PhD in
epistemology (the theory of knowledge) from the University of Southern California (1978).
Bahnsen was a pillar of the Christian Reconstruction movement associated with
Rousas John Rushdoony. As such, Bahnsen was a leading proponent of
presuppositional apologetics. He lectured to a broad range of evangelical Christian groups at many colleges and conferences, in the United States and abroad. His 1985 debate with atheist scholar, the late Gordon
Stein, was dubbed The Great Debate, and remains a classic as well as a benchmark in Christian apologetics.
His early death came as a result of complications following his third heart surgery in December of 1995.
