6 It may not be out of place here to recall gratefully the principal and more useful contributions made successively by Our Predecessors toward this same end, which contributions may be considered as the complement or fruit of the movement so happily initiated by Leo XIII. And first of all Pius X, wishing "to provide a sure way for the preparation of a copious supply of teachers, who, commended by the seriousness and the integrity of their doctrine, might explain the Sacred Books in Catholic schools . . ." instituted "the academic degrees of licentiate and doctorate in Sacred Scripture . . .; to be conferred by the Biblical Commission"; he later enacted a law "concerning the method of Scripture studies to be followed in Clerical Seminaries" with this end in view, viz.: that students of the sacred sciences "not only should themselves fully understand the power, purpose and teaching of the Bible, but should also be equipped to engage in the ministry of the Divine Word with elegance and ability and repel attacks against the divinely inspired books"; finally "in order that a center of higher biblical studies might be established in Rome, which in the best way possible might promote the study of the Bible and all cognate sciences in accordance with the mind of the Catholic Church" he founded the Pontifical Biblical Institute, entrusted to the care of the illustrious Society of Jesus, which he wished endowed "with a superior professorial staff and every facility for biblical research"; he prescribed its laws and rules, professing to follow in this the "salutary and fruitful project" of Leo XIII.
