It's not clear to me that St. Tertullian is entirely consistent in what he says. However, by careful reading we can get some interesting ideas from him. Here are some things to think about as you read:
1. Obviously, Tertullian has a very negative view of what he calls "philosophy". You won't necessarily understand all of his comments about philosophy as it was practiced in the eastern Mediterranean region in Tertullian's day, but you can still get a general idea of what specific features of philosophy Tertullian points to as being bad. List the most important of these negative features, as you understand them.
2. A relatively mild interpretation of Tertullian's remarks goes like this: Tertullian is opposed to combining philosophical questioning and theorizing with Christian faith because Christian faith is complete without adding concepts and theories from philosophy, and to add philosophical ideas or theories just makes a dangerous mess of things. But take another look at the opening sentences of the quotation from Tertullian. Do you think those sentences say something quite bold about there being no role for human reasoning in matters of Christian faith? What is Tertullian really saying here?
3. Now look at the final three sentences of the Tertullian quotation, and think about how these sentences might contrast with things that Migliore said about the importance of having a dynamic, inquiring faith. Is there a disagreement between Migliore and Tertullian about the proper nature of Christian faith?
