14 The Professor may now safely pass on to the use of Scripture in matters of Theology. On this head it must be observed that in addition to the usual reasons which make ancient writings more or less difficult to understand, there are some which are peculiar to the Bible. For the language of the Bible is employed to express, under the inspiration of the Holy Ghost, many things which are beyond the power and scope of the reason of man - that is to say, divine mysteries and all that is related to them. There is sometimes in such passages a fullness and a hidden depth of meaning which the letter hardly expresses and which the laws of interpretation hardly warrant. Moreover, the literal sense itself frequently admits other senses, adapted to illustrate dogma or to confirm morality. Wherefore it must be recognized that the sacred writings are wrapt in a certain religious obscurity, and that no one can enter into their interior without a guide(32); God so disposing, as the Holy Fathers commonly teach, in order that men may investigate them with greater ardour and earnestness, and that what is attained with difficulty may sink more deeply into the mind and heart; and, most of all, that they may understand that God has delivered the Holy Scriptures to the Church, and that in reading and making use of His Word, they must follow the Church as their guide and their teacher. St. Irenaeus long since laid down, that where the charismata of God were, there the truth was to be learnt, and that Holy Scripture was safely interpreted by those who had the Apostolic succession.(33) His teaching, and that of other Holy Fathers, is taken up by the Council of the Vatican, which, in renewing the decree of Trent declares its "mind" to be this - that "in things of faith and morals, belonging to the building up of Christian doctrine, that is to be considered the true sense of Holy Scripture which has been held and is held by our Holy Mother the Church, whose place it is to judge of the true sense and interpretation of the Scriptures; and therefore that it is permitted to no one to interpret Holy Scripture against such sense or also against the unanimous agreement of the Fathers."(34) By this most wise decree the Church by no means prevents or restrains the pursuit of Biblical science, but rather protects it from error, and largely assists its real progress. A wide field is still left open to the private student, in which his hermeneutical skill may display itself with signal effect and to the advantage of the Church. On the one hand, in those passages of Holy Scripture which have not as yet received a certain and definitive interpretation, such labours may, in the benignant providence of God, prepare for and bring to maturity the judgment of the Church; on the other, in passages already defined, the private student may do work equally valuable, either by setting them forth more clearly to the flock and more skilfully to scholars, or by defending them more powerfully from hostile attack. Wherefore the first and dearest object of the Catholic commentator should be to interpret those passages which have received an authentic interpretation either from the sacred writers themselves, under the inspiration of the Holy Ghost (as in many places of the New Testament), or from the Church, under the assistance of the same Holy Spirit, whether by her solemn judgment or her ordinary and universal magisterium (35) - to interpret these passages in that identical sense, and to prove, by all the resources of science, that sound hermeneutical laws admit of no other interpretation. In the other passages, the analogy of faith should be followed, and Catholic doctrine, as authoritatively proposed by the Church, should be held as the supreme law; for, seeing that the same God is the author both of the Sacred Books and of the doctrine committed to the Church, it is clearly impossible that any teaching can by legitimate means be extracted from the former, which shall in any respect be at variance with the latter. Hence it follows that all interpretation is foolish and false which either makes the sacred writers disagree one with another, or is opposed to the doctrine of the Church. The Professor of Holy Scripture, therefore, amongst other recommendations, must be well acquainted with the whole circle of Theology and deeply read in the commentaries of the Holy Fathers and Doctors, and other interpreters of mark.(36) This is inculcated by St. Jerome, and still more frequently by St. Augustine, who thus justly complains: "If there is no branch of teaching, however humble and easy to learn, which does not require a master, what can be a greater sign of rashness and pride than to refuse to study the Books of the divine mysteries by the help of those who have interpreted them?"(37) The other Fathers have said the same, and have confirmed it by their example, for they "endeavoured to acquire the understanding of the Holy Scriptures not by their own lights and ideas, but from the writings and authority of the ancients, who in their turn, as we know, received the rule of interpretation in direct line from the Apostles."(38) The Holy Fathers "to whom, after the Apostles, the Church owes its growth - who have planted, watered, built, governed, and cherished it,"(39) the Holy Fathers, We say, are of supreme authority, whenever they all interpret in one and the same manner any text of the Bible, as pertaining to the doctrine of faith or morals; for their unanimity clearly evinces that such interpretation has come down from the Apostles as a matter of Catholic faith. The opinion of the Fathers is also of very great weight when they treat of these matters in their capacity of doctors, unofficially; not only because they excel in their knowledge of revealed doctrine and in their acquaintance with many things which are useful in understanding the apostolic Books, but because they are men of eminent sanctity and of ardent zeal for the truth, on whom God has bestowed a more ample measure of His light. Wherefore the expositor should make it his duty to follow their footsteps with all reverence, and to use their labours with intelligent appreciation.
