Note:
Christian scholarship could mean scholarship of Christian topics. Or it could mean scholarship carried out by Christians. Theodore Graebner here first means study of Christian subjects (Bible, church history, doctrine, etc.) as carried out by pastors — he was writing at a seminary to pastors and to future pastors — but he also means their scholarship of any subjects OR that by any other faithful people.

Quote:
“Christian scholarship is but organized and well-proportioned knowledge, imbued with lofty purpose and spiritual ideals. And to treat it as if a contrast existed between its acquisition and practical usefulness is in itself an indication of undisciplined thinking.” (p. 42)

“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.” (p. 44)
