What I find particularly lacking amongst contemporary Orthodox theologians is any serious and constructive engagement with the Western fathers and with Western theology. I’m thinking, for example, of the kind of engagement exemplified in Hans Urs von Balthasar’s engagement with Karl Barth. Von Balthasar did not cease being Catholic after his encounter with the Church Dogmatics, but it’s also clear that his faith was not untouched. He became a better Catholic because of his serious attempt to understand Barth and learn from him. Orthodox engagement with Western theology is typically restricted to polemical criticism. I understand the motivation in adopting such a stance when one is striving to establish boundaries, engage in vigorous evangelism, and strengthen ecclesial identity; but I still question its catholicity.
As one might expect, the author's words have provoked a good number of comments.
Incidentally, one of my goals this year is to take up Jaroslav Pelikan's The Spirit of Eastern Christendom. One of these days.
Update: Good response by Jamie (the "inveterate Augustinian") at Ad Limina Apostolorum. =)
