Yesterday, I cited the work of Robert P. George, a director of the Institute on Religion and Democracy, as well as being the McCormick Professor of Jurisprudence at Princeton University. He also writes for Toward Tradition.
Here are two fine examples of his work:
An interview with Kathryn Jean Lopez, from NRO on the subject of just war.
A response regarding the issue of ecumenism, to a speech given by Dr. Tom Oden, of IRD, "The New Ecumenism" (the last three paragraphs are great!)
