Aquinas Institute's Opera Omnia Series


President: John Mortenson

Having received his bachelor’s degree in 1997 from Thomas Aquinas College, John Mortensen spent the next ten years in Europe where he studied theology and philosophy in Austria, Oxford, and Rome. From 2002 to 2007 he was Assistant Professor at the International Theological Institute in Gaming, Austria, teaching courses in logic, natural philosophy, metaphysics, fundamental theology, and Trinitarian theology. During these years he also held the positions of Director of Finance and subsequently Vice President of Administration. He completed a doctorate in philosophy at the Pontifical University of the Holy Cross in Rome and is currently working on his doctoral dissertation in theology. Dr. Mortensen’s research has centered on Aquinas’s doctrine of analogy, especially as it pertains to St. Thomas’s account of the mystery of the Trinity and of the divine causality of human freedom. He specializes in the work of Aristotle and Aquinas, but his interests also include spiritual theology (above all in the Carmelite tradition) and Mariology.

Managing Editor: Dr. John P. Joy

After completing his undergraduate studies at Ave Maria College in Michigan, John obtained master’s and licentiate degrees in theology at the International Theological Institute in Austria, where he wrote theses on Thomas Aquinas’ understanding of the efficacy of Christ’s passion and on papal infallibility. He wrote his doctoral dissertation on the distinction between the ordinary and extraordinary magisterium. He specializes in fundamental dogmatic theology, especially issues of magisterial authority and infallibility. Other areas of interest include liturgy and sacraments and the philosophy and theology of St. Thomas Aquinas.

About the series

“The Opera Omnia project,” pioneered by the Aquinas Institute, aims to publish the complete works of St. Thomas Aquinas in a Latin-English Bilingual Edition. The goal is to have each work available in Latin and English in three formats: online, eBook and print.
