Pitting doctrine against devotion is a false dichotomy because God intends them to go together. They are not mutually exclusive; one without the other is incomplete. Here B.B. Warfield (1851–1921) makes this fact clear:
“The ministry is a ‘learned profession’; and the man without learning, no matter with what other gifts he may be endowed, is unfit for its duties. But learning, though indispensable, is not the most indispensable thing for a minister. ‘Apt to teach’—yes, the ministry must be ‘apt to teach’; and observe that what I say—or rather what Paul says—is ‘apt to teach.’ Not apt merely to exhort, to beseech, to appeal, to entreat; nor even merely, to testify, to bear witness; but to teach. And teaching implies knowledge: he who teaches must know. Paul, in other words, requires of you, as we are perhaps learning not very felicitously to phrase it, ‘instructional,’ not merely ‘inspirational,’ service. But aptness to teach alone does not make a minister; nor is it his primary qualification. It is only one of a long list of requirements which Paul lays down as necessary to meet in him who aspires to this high office. And all the rest concern, not his intellectual, but his spiritual fitness. A minister must be learned, on pain of being utterly incompetent for his work. But before and above being learned, a minister must be godly.
Nothing could be more fatal, however, than to set these two things over against one another. Recruiting officers do not dispute whether it is better for soldiers to have a right leg or a left leg: soldiers should have both legs. Sometimes we hear it said that ten minutes on your knees will give you a truer, deeper, more operative knowledge of God than ten hours over your books. ‘What!’ is the appropriate response, ‘than ten hours over your books, on your knees?’ Why should you turn from God when you turn to your books, or feel that you must turn from your books in order to turn to God? If learning and devotion are as antagonistic as that, then the intellectual life is in itself accursed, and there can be no question of a religious life for a student, even of theology. . . . Just because you are students of theology, it is understood that you are religious men—especially religious men, to whom the cultivation of your religious life is a matter of the profoundest concern—of such concern that you will wish above all things to be warned of the dangers that may assail your religious life, and be pointed to the means by which you may strengthen and enlarge it. In your case there can be no ‘either-or’ here—either a student or a man of God. You must be both.”
