Warum sich ein Theologe mit der Philosphiegeschichte herumschlug

James T. Dennison Jr. schreibt in seinem biografischen Essay „Geerhardus Vos: Between Two Worlds“ über den Theologen Vos (1861-1949):

Yet this Geerhardus Vos is best known to us for his biblical exegesis and biblical theology. How is it that in his Ph. D. program, he spends long hours in lectures on the history of philosophy? Because Vos understood, as few students today understand, that every intellectual movement is undergirded by philosophy. Even Old Testament, New Testament, and Pauline Theology of the late nineteenth century was driven by philosophy. … that is why when we read Vos, we are reading a man who understands—understands the critics and unmasks their presuppositions by reducing their systems to the horizontal plane, above which no critical approach can rise. And, I may add, Vos unmasks the agenda of conservative systems—even fundamentalistic and broad evangelical moralism—which imitates liberalism by reducing the Biblical text to the horizontal.
