“The strongest indictment against nineteenth-century liberalism was that waged by the Swiss theologian Emil Brunner in his classic work Das Midler, or The Mediator. In this work, he talked about the Christology developed in nineteenth-century theology that resulted in the denial of the deity of Christ and of His substitutionary atonement. Brunner said that he could define the essence of nineteenth-century liberalism in one word, and the word was unglaube, or unbelief. He said that nineteenth-century liberalism was a monument to unbelief.” -R.C. Sproul, What is The Church?
