Biography

On a leisurely walk by the river Ilisus, just outside the walls of the ancient city, Socrates responds to his persistent interlocutor, “You know, Phaedrus, writing shares a strange feature with painting. The offsprings of painting stand there as if they were alive, but if anyone asks them anything, they remain most solemnly silent. The same is true of written words” (Phaedrus 275d).

I was born and raised by the shadow of the Acropolis, a stone's throw away from the bank of the Ilisus river where Socrates took the young Phaedrus for that famous walk; and though the sounds and smells of the megalopolis have for generations replaced the bucolic descriptions of Plato, the ancient sentiments remain the same: writing and, even more, reading, is a tricky business; especially as one engages sacred Scripture and the history and theology of the Church. This endeavor, most rewarding of all, demands attention, perseverance, and a curious and open mind to really engage the multifaceted vision of the Painter, the author of the beauty that confronts us.

My research and writing interests focus on this dynamic relationship between the written documents and their interpretation in early Christianity. I pay particular attention to the development of Christological and Trinitarian thought, as well as the interplay of classical Greco-Roman and early Christian philosophical understandings, biblical hermeneutics, and ethics. Whether I study history or theology, first I seek to study the subject within its own historical, theological, and socio-political context so that I may understand it on its own terms; only then do I attempt to interpret it diachronically and explore its impact on theology and the life of the Church today.

For over thirty years I have had the opportunity to teach undergraduate and graduate students as they prepare to engage the world and the Church. Together, we are challenged to allow ourselves to become agents of change in a world in desperate need of God; to learn how to be, in Stanley Hauerwas' words, “a community of character.”

As I have had the opportunity to travel to post-war and post-disaster areas throughout the world and to serve as a Senior Fellow with the International Association for Refugees (IAFR) in the past decade, the urgency of developing such communities has become ever more clear. That is why I also write, teach, and lecture nationally and internationally on ethics, human rights, and on the plight of persons seeking refuge from forced displacement.

My wife, Irene, and I share this goal and vision with our local congregation where we serve in missions, the worship arts programs, and in adult and children’s education.
