“So comprehensive are the labors of the ministerial calling, and at so many points do they touch human life, that there is hardly conceivable a domain of human knowledge which may not contribute its quota to the efficiency of pastoral labor. This is, indeed, a wonderful thing.”
Graebner, Theodore. The Pastor as Student and Literary Worker: Lectures Delivered at Concordia Seminary, St. Louis. Second, revised edition. St. Louis : Concordia Publishing House, 1925, p. 44.
Consecrating the study of virtually any subject (done in the service of the Gospel), Graebner broadens the fields of labor for Christian scholars and encourages us to follow our interests because one never knows how bits and pieces (or chunks and whole slabs) of knowledge can later be used for Christ by pastors. He then gives practical examples.
