I came to The University of Dallas in 2001 and am daily grateful for the privilege of establishing my profession here. The Constantine College of Liberal Arts at UD is unique. In my opinion, it offers the nation's best Catholic education in the liberal arts. The Core Curriculum is outstanding, and the students have a delightfully inquisitive edge, asking difficult questions as they attempt to integrate their learning from Core classes. They discuss Nietzsche and Augustine, Dante and Homer, Ignatius of Antioch and John Calvin, over coffee at the Cap Bar—even late at night, while snacking in their kitchens. Whether they are Catholic or non-Catholic, whether they are Christian or Jewish or Muslim, whether they are religious or not, they find here a place to discuss, to learn, and to grow – to trace their way back to first principles.

When they graduate, they wish to act deliberately in life, rather than merely to succeed outwardly while inwardly living lives of "quiet desperation." This deliberate approach to life sometimes leads to a year or two of post-graduation puzzlement (Parents, read: uncertainty about what to do). Thankfully, UD has been steadily developing its Career Services in ways that will lead students to excellent and well-suited employment opportunities. They deserve to be hired well, and they are going to be hired well. Ultimately, a deliberate approach leads not only to virtue but to material success—success in areas that resonate deeply with the graduate's noblest desires.

I approach the theological vocation with the conviction that philosophy and theology, faith and reason, serious intellectual research and fidelity to the full deposit of Catholic faith, work harmoniously toward one end, the contemplation and love of truth. As a teacher, I strive to induct my students into the adventures of theological inquiry, beginning with a solid foundation in Scripture and Catholic Tradition and culminating in dialogue with contemporary theologians, with other Christian faiths, and with contemporary philosophy.

As a theologian, I specialize in theological anthropology, approached from both Christological and Trinitarian perspectives. I have published on the issue of justification, with particular interest in the contemporary ecumenical dialogue between Lutherans and Catholics. My theological goal is to strike a balance between the rigorous discipline of Thomas Aquinas and the breadth of Catholic Tradition. Following John Paul II's landmark encyclical Fides et ratio, I anchor my theological reflections in philosophical realism and metaphysics. I find that Aristotle and Thomas Aquinas—who also borrowed from the Platonic notion of participation and from classical Roman philosophical sources—provide a reliable foundation for many fundamental matters. In fact, it is here that we find the sources of the "perennial philosophy," which itself is the basis of rightly done theology.

Of course, potentially fruitful philosophical resources for theology are many, ancient and recent. Guided by the penetrating light of the perennial philosophy, one can harvest the fruit from modern, recent, and contemporary philosophies and as a result more fully explore the depositum fidei. Without the light of the perennial philosophy, one easily falls into the ever-recurring and many-faced errors of Modernism, an eclectic and self-transforming heresy condemned by Pope St. Pius X.

Alasdair MacIntyre's work comes to mind as, among other things, a mapping of fruitful avenues divergent traditions might take in responsible discourse. Robert Sokolowski's work comes to mind as enabling theologians to bring to conscious reflection the ways we come at Christian things and the ways they manifest themselves to us. Recent thomistic philosophers are retrieving an Aristotelian-Thomistic approach to metaphysics that responsibly engages recent philosophy, esp. the "onto-theological critiques" of Kant and Heidegger. The perennial philosophy is by no means dead. It is not a "past historical school". It is rather the rational sub-structure of authentic thinking, that thinking which ought to inform any endeavor of theology.

The theological task is never ending; that's one reason it is so exciting. It is not the never ending of the numerical series; it is not the never ending of trash collections or bills or health checkups. It is the never ending exploration of God who is his own being, and is so in an explosive way: Pure Act from Pure Act, and from them both proceeding – Pure Act!
