This is clearly stated by the recent encyclical Pascendi: “In judging of pious traditions, the following must be kept in mind: the Church employs such prudence in treating of these matters that she does not allow such traditions to be written about except with great precaution and only after making the declarations required by Urban VIII.; and even then, after this has been properly done, the Church by no means asserts the truth of the private revelation or of the tradition, but merely permits them to be believed, provided there be sufficient human reasons. It was in this sense that the Sacred Congregation of Rites declared thirty-one years ago: ‘These apparitions are neither approved nor condemned by the Holy See; it merely permits them to be believed in a natural way, provided the tradition on which they rest be corroborated by credible testimonies and documents.’Whoever follows this maxim is safe. The veneration of such things is always conditional, it is only relative, and on the condition that the tradition be true. In so far only is the veneration absolute as it relates to the Saint to whom the veneration is paid. The same applies to the veneration of relics.” (Benedict XIV. says of private revelations: “Praedictis revelationibus etsi approbatis, non debere nec posse a nobis adhiberi assensum fidei catholicae, sed tantum fidei humanae juxta regulas prudentiae, juxta quas praedictae revelationes sunt probabiles et pie credibiles.” De Serv. Dei beatificatione, III, c. ult. n. 15).
Hence the historian is free to investigate such traditions critically, provided, of course, that he does not violate the reverence due to sacred things.
4. Infallible and Non-Infallible Teachings.
Now to consider a last point. Does it not rest entirely with the pleasure of ecclesiastical authority, as would seem from what has been said above, to suppress at any time the results, or at least the hypotheses, of scientific research by pointing to putative truths of faith presumed to be in opposition? Then, of course, the scientist would be at the mercy of a zealous ecclesiastical authority. Or will it perhaps be said that this authority is infallible in its every decision? Think of Galileo, of the interdict against the Copernican view of the world, and you will be able fully to appreciate the danger alluded to!
We shall later on return to the famous case of Galileo. For the present we only call attention to a distinction which must not be overlooked, the distinction between infallible teachings and those that are not infallible.[3]
According to Catholic teaching, the universal teaching body of the Church, when declaring unanimously to be an object of faith something relating to faith and morals, is endowed with infallibility, and also when in its daily practice of the faith it unanimously professes a doctrine to be a truth of faith. This infallibility is also possessed by the Pope alone when, acting in his capacity as Supreme Teacher of the Church in matters of faith and morals, he intends to give a permanent decision for the whole Church (ex cathedra).
Besides these infallible teachings there are also non-infallible teachings, and they are the more frequent. Such are, first of all, the ordinary doctrinal utterances of the Pope himself in his regular supervision of the teaching of doctrine: these instructions and declarations are of a lower kind than those peremptory [pg 098] ones that are pronounced ex cathedra: he is infallible only in the utterance of these ultimate, supreme decisions, the chief bulwark, as it were, erected against the floods of error. Decisions ex cathedra are very rare. Encyclical letters, too, are, as a rule, not infallible. It is self-evident that the theological opinions and statements of the Pope as a private person, not as Supreme Head of the Church, do not belong here at all. They have no official character and are in no way binding.
Among decisions that are not infallible are further included, in various degrees, the doctrinal utterances of Bishops, of particular synods, and especially those of the Roman Congregations. The latter are bodies of Cardinals, delegated by the Head of the Church, as highest Papal boards, to co-operate with him in the various offices of administration. Of these, the Congregation of the Holy Office and that of the Index may also render decisions on doctrinal questions. Although the Congregations act by virtue of their delegation from the Pope, and publish their decrees with his consent, the decisions are not decisions of the Pope himself, but remain decisions of the Cardinals. Much less can the infallibility of the Pope pass over to them: it is his personal prerogative, the aid of the Holy Ghost is promised to him, and protects his judgments under certain conditions against error.
But the Catholic owes submission also to the non-infallible teachings; and not only an outer submission, a reverent silence, that offends not either verbally or in writing against the decision rendered, but he owes also his inner assent. But it cannot be that unconditional inner assent which he owes to the infallible decision, for this he holds to be irrevocably certain; nor is his assent to non-infallible decisions a real act of faith. He is not given any unconditional guarantee of the truth. An error is, of course, most unlikely, but not absolutely impossible. Hence the faithful Catholic should always be ready to accept such decisions in as far as they are warranted by recognized truth. This applies to all kinds of doctrinal teaching, but of course in different ways, corresponding to the degree of authority,—for instance, Papal decisions are of higher authority than those of the Congregations,—yet it applies also to the [pg 099] doctrinal decisions of the Congregations, because they are the ordinary teaching organs of the Church.
When the Congregation of the Index, 1857, had forbidden the works of Guenther and many thought they could evade the decision, Pius IX.wrote, June 15, to the Archbishop of Cologne: “The decree is so far-reaching that nobody may think himself free not to hold what we have confirmed.” Similar was what the Pope had written to the Archbishop of Mecheln after the condemnation of the ontological errors of Ubagh. The Motu proprio of Pius X. of November 8, 1907, speaks similarly of the obligation of submission to the decisions of the Papal Biblical Commission relating to doctrines, and to the decrees of Congregations when approved by the Pope. (Cf. also the Syllabus of Pius IX., sent. 22.)
