Cornelius Van Til (1895–1987) was one of the most respected apologetic theologians of his time. Van Til earned degrees from Calvin College, Princeton Theological Seminary, and Princeton University on his way to becoming an Orthodox Presbyterian Minister.
He served throughout the ministry and scholarly fields, including serving as a professor of apologetics at Westminster Theological Seminary and Princeton Theological Seminary and being heavily involved with the foundation of the Philadelphia-Montgomery Christian Academy.
His most noted writings include The New Modernism, The Defense of the Faith, and Christianity and Barthianism which can all be found in The Works of Cornelius Van Til (40 vols.). Much of his work with apologetics focuses on presuppositions, the difference between believers and non-believers, and the opposition between Christian and non-Christian worldviews.
