Enough, probably, has been done in our other books ¹ in the way of answering the ignorant and profane attacks which the Manichaeans make on the law, which is called the Old Testament, in a spirit of vainglorious boasting, and with the approval of the uninstructed. Here, too, I may shortly touch upon the subject. For every one with average intelligence can easily see that the explanation of the Scriptures should be sought for from those who are the professed teachers of the Scriptures; and that it may happen, and indeed always happens, that many things seem absurd to the ignorant, which, when they are explained by the learned, appear all the more excellent, and are received in the explanation with the greater pleasure on account of the obstructions which made it difficult to reach the meaning. This commonly happens as regards the holy books of the Old Testament, if only the man who meets with difficulties applies to a pious teacher, and not to a profane critic, and if he begins his inquiries from a desire to find truth, and not in rash opposition. And should the inquirer meet with some, whether bishops or presbyters, or any officials or ministers of the Catholic Church, who either avoid in all cases opening up mysteries, or, content with simple faith, have no desire for more recondite knowledge, he must not despair of finding the knowledge of the truth in a case where neither are all able to teach to whom the inquiry is addressed, nor are all inquirers worthy of learning the truth. Diligence and piety are both necessary: on the one hand, we must have knowledge to find truth, and, on the other hand, we must deserve to get the knowledge.
