" Nineteenth-century liberal theology sought to reduce Christianity to a naturalized religion, stripped of everything supernatural. The Christian message was reduced to matters of ethics and values; the gospel was recast as a kind of humanitarianism that attempts to alleviate pain and suffering in this world. Everything supernatural in Scripture was denied, including the deity of Christ. His substitutionary atonement, resurrection, and ascension were all rejected. Modern theology took hold of churches and educational institutions. "
