Born in Baltimore, Dr. Marshner was raised in the Lutheran Church. He pursued his undergraduate studies at Gettysburg College as a pre-ministerial student. An interest in Old Testament exegesis led him to postpone entry into the Lutheran seminary in order to pursue a degree at the Yale graduate school, where he studied Hebrew, Akkadian, Aramaic, and other Semitic languages. The impossibility of reconciling the historical-critical method of exegesis with the method of Christ and his Apostles forced him to deeper philosophical and theological questions. His studied finally brought him to be received into the Catholic Church, in 1967. Dr. Marshner is a Thomistic theologian, ethicist, and a founding professor at Christendom College in Front Royal, Virginia.
