Scott Hahn

After receiving his education at Gordon–Conwell Theological Seminary, Hahn started out as a pastor at Trinity Presbyterian Church in Fairfax, Virginia. Since that time, he has held a variety of positions at institutes, seminaries, and universities.

Hahn's wife, Kimberly, had a similar conversion at a slightly later date, entering the Catholic Church at Easter 1990 in Joliet, Illinois. Rome Sweet Home describes their process of conversion together.

Since 1990, Hahn has taught at the Franciscan University of Steubenville, where he is the Father Michael Scanlan, TOR, Chair of Biblical Theology and the New Evangelization. He was awarded Doctor of Humanities – honoris causa, by the Pontifical Catholic University of Puerto Rico in 2004. In 2014, Francis Cardinal George appointed Hahn to the newly established McEssy Distinguished Visiting Professorship in Biblical Theology at Mundelein Seminary in Chicago.

Hahn converted to Catholicism at Easter 1986 in Milwaukee, Wisconsin. He came to be called "Luther in reverse", from his wife's words.

Hahn received his B.A. degree magna cum laude in 1979 from Grove City College in Pennsylvania with a triple major of theology, philosophy, and economics. He obtained his M.Div. degree summa cum laude from Gordon–Conwell Theological Seminary in 1982. In May 1995, he was awarded a Ph.D. degree in systematic theology from Marquette University (Phi Beta Kappa). His dissertation is entitled "Kinship by Covenant: A Biblical Theological Analysis of Covenant Types and Texts in the Old and New Testaments". A version was published by Yale University Press in 2009 as Kinship by Covenant: A Canonical Approach to the Fulfillment of God's Saving Promises.

Scott W. Hahn (born October 28, 1957) is an American Christian theologian and apologist. A former Presbyterian who converted to Catholicism, Hahn's popular works include Rome Sweet Home and The Lamb's Supper: The Mass as Heaven on Earth. His lectures have been featured in multiple audio distributions through Lighthouse Catholic Media. Hahn is known for his research on Early Christianity during the Apostolic Age and various theoretical works concerning the early Church Fathers.

As a young man, Hahn was convinced that the Catholic Church was in error and boasted of having converted some Catholics into embracing a purer Christianity. His conversion began when he and his wife became convinced that contraception was contrary to God's law. He was also bothered that the Catholic Church was the only Christian church tradition that upheld the ancient teaching of prohibiting contraception that Protestants abandoned in the 1930s. Hahn continued to study various issues relating to salvation, faith, and good works, as well as the Protestant doctrine of sola scriptura.
