Dagg, D.D. Dr. Dagg wrote the first Southern Baptist Systematic Theology. Readers will note that Dagg is thoroughly Reformed and Baptist. His theology is the theology of the founders of the Southern Baptist Convention."...What was spoken and written by inspiration, came with as high authority as if it had preceded from God without the use of human instrumentality... Their peculiarities of thought, feeling, and style had no more effect to prevent what they spoke end wrote from being the word of God, than their peculiarities of voice or of chirography.The question, whether inspiration extended to the very words of revelation, as well as to the thoughts and reasonings, is answered by Paul: 'We preach, not in the words which men's wisdom teacheth, but which the Holy Ghost teacheth.'"John L.
