The point to be observed for our present purpose is the position given Exegetical Theology as the first among these four [departments of theology]. The precedence is due to the instinctive recognition that at the beginning of all Theology lies a passive, receptive attitude on the part of the one who engages in its study. . . . It is eminently a process in which God speaks and man listens.
