I have already mentioned Whitaker, Muller, and Warfield. I recently called up Rev. David T. King (he’s been graciously commenting on my blog under the name D.T. King), in order to find out more about his volumes, and also what he would recommend for me to read. He is an OPC pastor in Elkton, MD. I just received his books in the mail today, and to say that I am impressed would be an understatement. I would highly recommend these volumes as the finest modern Protestant treatment of the subject. Volume 1 is a biblical argument for Sola Scriptura. Volume 2 is an historical argument for Sola Scriptura. Volume 3 is a catena of quotations from the early church fathers supporting Sola Scriptura. The importance of this set is in its response to modern Roman Catholic apologists on the issue of Scripture (especially the material and formal principles of Sola Scriptura), especially to the volume Not By Scripture Alone, edited by Robert Sungenis. At the very least, King/Webster’s set gives a complete lie to the notion that Protestants reject or ignore tradition.
When I was on the phone with Rev. King, he recommended three main sources: Muller and Whitaker, which we are going through right now, but he also highly recommended William Goode’s The Divine Rule of Faith and Practice. This set was written in the middle of the nineteenth century against the Tractarians at Oxford (Romanizers). According to Rev. King, it is one of the finest treatments of Sola Scriptura available anywhere. Fortunately for us, the volumes are available on the internet. Volume 1, volume 2, and volume 3 (this is the 1853, second enlarged edition). I will be reading all six of these recommended volumes.
