Apologetics and Polemics: W. G. T. Shedd

"When the work of deriving doctrines from Scripture has been done, the theologian must defend them against attacks, answering objections, and maintaining the reasonableness of revealed truth. The elder Protestant divines devoted great attention to this part of theological science, under the title Theologia polemica.12 Here is where religion and philosophy, faith and science meet. Human reason cannot reveal anything, but it can defend what has been revealed."
