One of the most exciting American Catholic theologians around today is Fr. Robert Barron. He wears many hats. He's an academic who writes brilliant works such as Bridging the Divide: Musings of a Post-Liberal, Post-Conservative Evangelical Catholic (Lenham, MD: Sheed and Ward, 2004) and The Priority of Christ: Toward a Postliberal Catholicism (Grand Rapids: Brazos Press, 2007). He's also a film critic (e.g., here and here).
Of course, he's also a pastor. Here are his thoughts on New Years resolutions
