7 All this in fine Our immediate Predecessor of happy memory Pius XI brought to perfection, laying down among other things "that no one should be appointed professor of Sacred Scripture in any Seminary, unless, having completed a special course of biblical studies, he had in due form obtained the academic degrees before the Biblical Commission or the Biblical Institute." He wished that these degrees should have the same rights and the same effects as the degrees duly conferred in Sacred Theology or Canon Law; likewise he decreed that no one should receive "a benefice having attached the canonical obligation of expounding the Sacred Scripture to the people, unless, among other things, he had obtained the licentiate or doctorate in biblical science." And having at the same time urged the Superiors General of the Regular Orders and of the religious Congregations, as well as the Bishops of the Catholic world, to send the more suitable of their students to frequent the schools of the Biblical Institute and obtain there the academical degrees, he confirmed these exhortations by his own example, appointing out of his bounty an annual sum for this very purpose.
