Joel Zartman is an alumnus of Central Seminary. His ministry experience includes pastoring a church in Colombia. He is presently a doctoral student in theology at Westminster Seminary. Here Joel begins with an observation of Thomas à Kempis as a preface to a reflection on what theology is for. Here is his conclusion.
What I am sure of is this: you cannot drive a wedge between speculative and practical theology. They must be related. They have to be coordinated. The complex relationship should be clear to us, explicit. And we should beware of those who do not value both.
