15. Moreover, they assert that when Catholic doctrine has been reduced to this condition, a way will be found to satisfy modern needs, that will permit of dogma being expressed also by the concepts of modern philosophy, whether of immanentism or idealism or existentialism or any other system. Some more audacious affirm that this can and must be done, because they hold that the mysteries of faith are never expressed by truly adequate concepts but only by approximate and ever changeable notions, in which the truth is to some extent expressed, but is necessarily distorted. Wherefore they do not consider it absurd, but altogether necessary, that theology should substitute new concepts in place of the old ones in keeping with the various philosophies which in the course of time it uses as its instruments, so that it should give human expression to divine truths in various ways which are even somewhat opposed, but still equivalent, as they say. They add that the history of dogmas consists in the reporting of the various forms in which revealed truth has been clothed, forms that have succeeded one another in accordance with the different teachings and opinions that have arisen over the course of the centuries.
16. It is evident from what We have already said, that such tentatives not only lead to what they call dogmatic relativism, but that they actually contain it. The contempt of doctrine commonly taught and of the terms in which it is expressed strongly favor it. Everyone is aware that the terminology employed in the schools and even that used by the Teaching Authority of the Church itself is capable of being perfected and polished; and we know also that the Church itself has not always used the same terms in the same way. It is also manifest that the Church cannot be bound to every system of philosophy that has existed for a short space of time. Nevertheless, the things that have been composed through common effort by Catholic teachers over the course of the centuries to bring about some understanding of dogma are certainly not based on any such weak foundation. These things are based on principles and notions deduced from a true knowledge of created things. In the process of deducing, this knowledge, like a star, gave enlightenment to the human mind through the Church. Hence it is not astonishing that some of these notions have not only been used by the Oecumenical Councils, but even sanctioned by them, so that it is wrong to depart from them.
17. Hence to neglect, or to reject, or to devalue so many and such great resources which have been conceived, expressed and perfected so often by the age-old work of men endowed with no common talent and holiness, working under the vigilant supervision of the holy magisterium and with the light and leadership of the Holy Ghost in order to state the truths of the faith ever more accurately, to do this so that these things may be replaced by conjectural notions and by some formless and unstable tenets of a new philosophy, tenets which, like the flowers of the field, are in existence today and die tomorrow; this is supreme imprudence and something that would make dogma itself a reed shaken by the wind. The contempt for terms and notions habitually used by scholastic theologians leads of itself to the weakening of what they call speculative theology, a discipline which these men consider devoid of true certitude because it is based on theological reasoning.
18. Unfortunately these advocates of novelty easily pass from despising scholastic theology to the neglect of and even contempt for the Teaching Authority of the Church itself, which gives such authoritative approval to scholastic theology. This Teaching Authority is represented by them as a hindrance to progress and an obstacle in the way of science. Some non-Catholics consider it as an unjust restraint preventing some more qualified theologians from reforming their subject. And although this sacred Office of Teacher in matters of faith and morals must be the proximate and universal criterion of truth for all theologians, since to it has been entrusted by Christ Our Lord the whole deposit of faith - Sacred Scripture and divine Tradition—to be preserved, guarded and interpreted, still the duty that is incumbent on the faithful to flee also those errors which more or less approach heresy, and accordingly "to keep also the constitutions and decrees by which such evil opinions are proscribed and forbidden by the Holy See,"[2] is sometimes as little known as if it did not exist. What is expounded in the Encyclical Letters of the Roman Pontiffs concerning the nature and constitution of the Church, is deliberately and habitually neglected by some with the idea of giving force to a certain vague notion which they profess to have found in the ancient Fathers, especially the Greeks. The Popes, they assert, do not wish to pass judgment on what is a matter of dispute among theologians, so recourse must be had to the early sources, and the recent constitutions and decrees of the Teaching Church must be explained from the writings of the ancients.
19. Although these things seem well said, still they are not free from error. It is true that Popes generally leave theologians free in those matters which are disputed in various ways by men of very high authority in this field; but history teaches that many matters that formerly were open to discussion, no longer now admit of discussion.
20. Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent, since in writing such Letters the Popes do not exercise the supreme power of their Teaching Authority. For these matters are taught with the ordinary teaching authority, of which it is true to say: "He who heareth you, heareth me";[3] and generally what is expounded and inculcated in Encyclical Letters already for other reasons appertains to Catholic doctrine. But if the Supreme Pontiffs in their official documents purposely pass judgment on a matter up to that time under dispute, it is obvious that that matter, according to the mind and will of the Pontiffs, cannot be any longer considered a question open to discussion among theologians.
21. It is also true that theologians must always return to the sources of divine revelation: for it belongs to them to point out how the doctrine of the living Teaching Authority is to be found either explicitly or implicitly in the Scriptures and in Tradition.[4] Besides, each source of divinely revealed doctrine contains so many rich treasures of truth, that they can really never be exhausted. Hence it is that theology through the study of its sacred sources remains ever fresh; on the other hand, speculation which neglects a deeper search into the deposit of faith, proves sterile, as we know from experience. But for this reason even positive theology cannot be on a par with merely historical science. For, together with the sources of positive theology God has given to His Church a living Teaching Authority to elucidate and explain what is contained in the deposit of faith only obscurely and implicitly. This deposit of faith our Divine Redeemer has given for authentic interpretation not to each of the faithful, not even to theologians, but only to the Teaching Authority of the Church. But if the Church does exercise this function of teaching, as she often has through the centuries, either in the ordinary or in the extraordinary way, it is clear how false is a procedure which would attempt to explain what is clear by means of what is obscure. Indeed, the very opposite procedure must be used. Hence Our Predecessor of immortal memory, Pius IX, teaching that the most noble office of theology is to show how a doctrine defined by the Church is contained in the sources of revelation, added these words, and with very good reason: "in that sense in which it has been defined by the Church."
22. To return, however, to the new opinions mentioned above, a number of things are proposed or suggested by some even against the divine authorship of Sacred Scripture. For some go so far as to pervert the sense of the Vatican Council's definition that God is the author of Holy Scripture, and they put forward again the opinion, already often condemned, which asserts that immunity from error extends only to those parts of the Bible that treat of God or of moral and religious matters. They even wrongly speak of a human sense of the Scriptures, beneath which a divine sense, which they say is the only infallible meaning, lies hidden. In interpreting Scripture, they will take no account of the analogy of faith and the Tradition of the Church. Thus they judge the doctrine of the Fathers and of the Teaching Church by the norm of Holy Scripture, interpreted by the purely human reason of exegetes, instead of explaining Holy Scripture according to the mind of the Church which Christ Our Lord has appointed guardian and interpreter of the whole deposit of divinely revealed truth.
23. Further, according to their fictitious opinions, the literal sense of Holy Scripture and its explanation, carefully worked out under the Church's vigilance by so many great exegetes, should yield now to a new exegesis, which they are pleased to call symbolic or spiritual. By means of this new exegesis of the Old Testament, which today in the Church is a sealed book, would finally be thrown open to all the faithful. By this method, they say, all difficulties vanish, difficulties which hinder only those who adhere to the literal meaning of the Scriptures.
