I was browsing through the SBC book store at a nearby seminary and came across a series of commentaries that included Catholic theologians Raymond Brown, Pheme Perkins, and Irene Nowell. All subscribe to "higher criticism", for lack of a better term. I asked a question or two and the series was highly recommended and, supposedly, was being used in the seminary. I didn't realize the SBC was going that route in terms of Bible study. What Bible commentary would you recommend? What basic theology text would be best? I was looking for Millard Erickson's "Christian Theology," but it wasn't in stock.
