Broadening, but also deepening
As a newly converted atheist, my study of Christianity began at Westminster Seminary in Philadelphia. Westminster was an outgrowth of J. Gresham Machen's separation from mainline Presbyterianism. It was, and still is, a bastion of Reformed orthodoxy.
Westminster's great strength was its stress on the authority of Scripture as the ultimate norm of faith and practice. Classes on the Old and New Testament were invigorating and faith-inspiring, carefully, though often critically, related to current scholarship. Theology courses had a polemic flavor, but immersed students in the worldview of the Westminster Confession. Historian Paul Wooley -- the only Democrat on the faculty -- exposed us to important primary sources, including Soren Kierkegaard and Jonathan Edwards.
