Apologetics — The Truth, The Whole Truth, And Nothing But The Truth

A paperback primer on the presuppositional method adapted from an oral presentation offered by Dr. Bahnsen during an informal debate with Dr. R.C. Sproul in 1977 at the Reformed Theological Seminary in Jackson, Mississippi.

“This booklet offers a most concise, yet thorough-going presentation of Presuppositional Apologetics. Bahnsen’s rigorous exegesis, logical consistency and cogent style provide a superbly persuasive primer on defending the Christian faith in a Biblical manner. This resource will prove particularly valuable for those involved in ministry to an unbelieving culture.”

Brian De Jong, Pastor of Grace OPC (Sheboygan, WI)

“Never was it more important for the Christian church to retain a right biblical apologetic than at the present. The raging age of skepticism and Christian apostasy calls for a rock-solid, biblically-based, presuppositional apologetic as so elegantly, simply, and succinctly laid out here by Dr. Greg Bahnsen. I recommend this for every Christian leader and lay person.”

Kevin Swanson, Pastor, and Director of Generations

“Derived from the classic informal debate between Greg Bahnsen and RC Sproul, “Apologetics” presents a concise summary of the fundamental principles of the presuppositional approach. This brief and succinct overview serves as a valuable resource, offering key insights into the biblical foundation of apologetics, making it beneficial for both experts and laypeople. I wholeheartedly recommend it.”

Eli Ayala, Director of Revealed Apologetics
