Dr. Christianson, who served a parish in Gary, Indiana, has taught early and medieval church history at the Seminary since 1967. He specializes in the theology and spirituality of the late Middle Ages, with additional interests in the history of worship and Christian art and architecture. The author and co-editor of several works on Nicholas of Cusa, the fifteenth century theologian and reformer and on the reform councils of that era, Dr. Christianson inaugurated the International Seminar on Pre-Reformation Theology which brings students and scholars from around the world to Gettysburg.
Among his most recent works, he is the co-author of The Spirituality of the German Awakening, a volume in the series Classics of Western Spirituality (2003), co-editor of Introducing Nicholas of Cusa: A Guide to a Renaissance Man (2004), and co-author of Reject Aeneas. Accept Pius: Selected Letters of Aeneas Sylvius Piccolomini (Pope Pius II) (2006).

He founded and for some years co-chaired Music, Gettysburg!, a major musical series formed by a partnership between the Seminary and the community, and co-hosts the weekly radio program The Seminary Explores which began in 1970.

Christianson is co-editor of The Church, the Councils, and Reform: The Legacy of the Fifteenth Century (2008).
