19 Today therefore, since this branch of science has attained to such high perfection, it is the honorable, though not always easy, task of students of the Bible to procure by every means that as soon as possible may be duly published by Catholics editions of the Sacred Books and of ancient versions, brought out in accordance with these standards, which, that is to say, unite the greatest reverence for the sacred text with an exact observance of all the rules of criticism. And let all know that this prolonged labor is not only necessary for the right understanding of the divinely-given writings, but also is urgently demanded by that piety by which it behooves us to be grateful to the God of all providence, Who from the throne of His majesty has sent these books as so many paternal letters to His own children.
