That’s a nice list from Leithart. Very helpful organization. He said it was personal, but I’d add the following to mine:

I. Theology
A. Political theology: Karl Barth, Jacques Ellul (gotta put him somewhere, either here or K.), John Howard Yoder, Miroslav Volf, Slavoj Zizek.
B. Aesthetics: Calvin Seerveld, Lambert Zuidervaart, Hans-Georg Gadamer
E. Theological ethics: Dietrich Bonhoeffer, Jeffrey Stout, William Placher, Richard B. Hays, John Howard Yoder (again)
F. Science and theology: Wentzel van Huyssteen, Hans Radder
K. Philosophical theology: Gabriel Marcel, Paul Ricoeur
L. Feminist theology: Sally McFague
Um, it would be fine to cross out M. and N. :-)

II. Biblical Theology
A. Historical Jesus: Richard Bauckham
D. Hermeneutics: Mark Wallace, Paul Ricoeur (again)
E. Literary Studies of the Bible: Craig Bartholomew, Calvin Seerveld (again)
