Evangelicals overall do a fine job at defending the trivial but struggle to defend the hard things. Machen observed long ago in his monumental Christianity and Liberalism that “it appears that the things that are sometimes thought to be hardest to defend are also the things that are most worth defending (8).”
Machen was deeply concerned about where the lines were being drawn. He was sure that if we abandoned this battle, we would be swallowed up by heresy and forsake the tremendous work of our godly forefathers. He saw liberalism as another religion altogether; a totally different class of religious expression than Christianity (7). He saw the resurrection, virgin birth, and the divinity of Jesus being threatened on a consistent basis. But, he argued, these are the battles worth fighting; they are the hard battles of the faith. Once we lose the creedal ground, we will sink into oblivion. For Machen, this was not an option.
