The pastor ought to have two voices: one, for gathering the sheep; and another, for warding off and driving away wolves and thieves. The Scripture supplies him with the means of doing both.
John CalvinWithout Christ, sciences in every department are vain....The man who knows not God is vain, though he should be conversant with every branch of learning. Nay more, we may affirm this too with truth, that these choice gifts of God -- expertness of mind, acuteness of judgment, liberal sciences, and acquaintance with languages, are in a manner profaned in every instance in which they fall to the lot of wicked men.
John Calvin
