61 Let the present-day commentators of the Sacred Scripture emulate, according to their capacity, what those illustrious interpreters of past ages accomplished with such great fruit; so that, as in the past, so also in these days, the Church may have at her disposal learned doctors for the expounding of the Divine Letters; and, through their assiduous labors, the faithful may comprehend all the splendor, stimulating language, and joy contained in the Holy Scriptures. And in this very arduous and important office let them have "for their comfort the Holy Books" and be mindful of the promised reward: since "they that are learned shall shine as the brightness of the firmament, and they that instruct many unto justice, as stars for all eternity."
