FIFTH SECTION. THEOLOGY.

Chapter I. Theology And Science.

Now one other, the concluding point. So far our discussion has dealt almost exclusively with the profane sciences, and while there were often under discussion general principles, applying also to theology, we did not refer to the latter expressly for the reason that it occupies a special position in regard to our question. Theology is the science of the faith, its subjects are truths established by divine or inspired authority; hence, in teaching, authority plays a larger part in this than in any other science. For this reason much fault is found with theology, and many consider that it forfeits thereby its claim to rank as a science. They say it lacks all liberty, the results are prescribed; it lacks possibility of progress; nothing but rigid dogmas, rejecting all development and improvement; its vocation is exhausted by the incessant transmitting of the immutable; hence it lacks all the essential conditions of a true science, it has no claim to a place at the university; if it nevertheless has established itself at the university, as is the case in some countries, it must be considered as an alien body, a remnant of an obsolete time.

A keen eye cannot fail to detect in these words the prompting voice of that view of the world which rejects everything supernatural, and declares that Christian dogmatics and morals, and ideas of sin, redemption, humility of faith, cross, and self-denial, do no longer correspond to modern man. At bottom is the struggle between the two views of the world-one the philosophy of modern, sovereign man, the other the contemplation of the world in the light of Christianity: a process of repulsion, psychologically easily understood, by which the one seeks to expel the other from the position which it desires to occupy. A closer examination of the matter will show this.

Theology as a Science.

Is theology a science in the proper sense? May it rightly claim a place among the branches of human science? This shall be the first question to be answered. Theology, meaning the doctrine of G.o.d, is the science of the Revelation, or of the faith; of the Revelation which began in the Old Testament and reached its perfection in Christ, the Son of G.o.d, in whom appeared the fulness of G.o.d, the image of the glory of G.o.d, the perfection of all religion; the Revelation intrusted to the Church to be preserved infallibly, so that by these truths, and means of salvation, the Church might guide and enrich the life of believing mankind. Hence, in the broad sense in which it is understood now, theology is the science that gathers the revealed truths from their sources, endeavours to grasp and to defend them, and to deduce new truths from them; which also studies these truths and the means given for salvation, in their development and effect in the Christian life.

Thus it includes a wide range of subordinate branches, connected by a common object. The biblical sciences have for their subject Holy Writ; the sciences of introduction to the Bible deal with its external history, with historical criticism playing an important part; exegesis is occupied with the scientific interpretation of the text and uncovers the treasures of truth in Holy Writ, a.s.sisted in this task by hermeneutics and a number of philosophical-historical auxiliary sciences. Ecclesiastical history and its branches of patrology, history of dogma, ecclesiastical archaeology, and art, and other auxiliary sciences, describe the doctrine of Revelation in its historical course through the centuries, and its development in the bosom of the Church. Dogmatics (with apologetics) and morals have the task to explain and defend the doctrine of faith and morals, as drawn from the Scriptures and from tradition, to deduce new truths from them and to unite them all in a system. Finally, Canon law, and even to a greater degree the departments of pastoral theology, homiletics, liturgy, show how the treasures of Revelation and Redemption find their realization in the practical life of the Church and of the Christian people.

Hence there cannot be any doubt but that theology is a science in the proper sense, unless a wrong definition of science is presumed. Of course, if we should identify science in general with empirical science, and scientific methods with the methods of natural sciences and mathematics, and refuse to recognize any results as scientific except those gained by observation and mathematical calculation, then, of course, theology would not be a science, nor would many other branches of knowledge come under this head; the fault, however, would lie with a narrow conception, that limits itself to the portion of human knowledge within its vision, ignoring everything that exists beyond its horizon.

What are we to understand by science? It is the systematic concentration of the knowledge and the research of things according to their causes; hence of our cognition of a subject that can be proved by careful demonstration to be certain or at least probable. This we find to be the case in theology. It is the sum total, systematically arranged, of knowledge and researches concerning the tenets of faith, considered in the abstract, in their history, and in their effects on the life of the Church. Applying the method of natural thought, theology first studies the presumptions and foundations of faith, examines the sources of revelation by the philosophical and historical-critical method, proves the doctrines of faith by these sources, endeavours to grasp these truths intellectually, by the methods of a.n.a.lytical and synthetical thinking, and to make clear their connection. We have here the same methods as applied in other sciences: ascertaining the facts, definition of terms, deduction, induction. In respect to the history of the Church and to Canon law their similarity with a.n.a.logous profane sciences is at once obvious.

There is one _difference_: in the theological sciences there is active, not only rational research, but also the _belief_ in revealed truths. In some departments, like that of ecclesiastical history, this difference is less p.r.o.nounced, they proceed by the method of critically establishing and connecting the facts; but they, too, are guided by the conviction that there is in the life of the Church not only natural causation, but also supernatural principle. Dogmatics takes faith to a greater degree as its point of support, in order to connect natural reason with the convictions of faith, and how richly natural reason may unfold itself is shown in the works of _St. Augustine_ and _St. Thomas_, on the great mysteries of the faith. As regards faith itself, we must keep in mind that it has a scientific foundation: the credibility of revelation is proven, it is a reasoning faith. It may be likened to history. The historian, on the testimony of his sources, believes in the actuality of human events, having convinced himself of the credibility of his sources; this belief becomes then his starting point for further researches of a pragmatical nature: he penetrates more deeply into the facts, and connects them according to their causal relations. The difference is this: the historian rests upon human authority, the theologian upon divine.

Yet the objection is raised: theology is faith, or at least rests on faith. Faith, however, has nothing to do with science; faith is sentiment, whereas science is knowledge. That this view of faith is wrong, and the result of subjective agnosticism that denies to man any positive understanding of supernatural truths, we have shown repeatedly. Certainly, if faith were nothing but sentiment, no science could be built upon it; you cannot build stone houses upon water. But the Catholic faith is not simply sentiment, it is a conviction of reason, based upon G.o.d's testimony that the revealed doctrines are true. In the same way that the historian-to use the comparison once more-believes positively in his historical facts, on the strength of the authority of a _Livy_ or _Tacitus_, or accepts as proved some events of ancient times, relying upon the testimony of Babylonian tablets of clay or upon the pyramids, and makes these events his starting point for further researches, without having to fear objections to his work on the ground that knowledge and belief are incompatible; just so the theologian believes in his religious truths because they are vouched for by G.o.d's testimony. This proves that the foundation for his further thought is not formed by uncontrollable, irrational sentiment, but by a conviction of reason.

Hence, if by knowledge is meant nothing but a conviction of reason-and in this sense faith and knowledge are usually contrasted by modern philosophical writers-then faith is knowledge in the proper sense and a contradiction does not exist. If, however, knowledge is taken to be the understanding gained by personal insight without reliance on external testimony, then, of course, there is a distinction, and theology would not be a science, in so far as it _believes_; just as little as history would be a science, in so far as it believes its sources. But theology is a science, in so far as it makes use of experience and reason, examines its sources, draws from them the facts of faith, and makes them the starting point for its investigations.

Theology also has mysteries among its subjects, namely, truths whose actuality is cognizable, but whose contents, while not indeed inconsistent, yet remain obscure and incomprehensible to us. But even this does not impair its scientific character. Other sciences share with it this lot of human limitation. Instances are plentiful in natural science where the existence of natural forces of one kind or another is proven; of which it is able to form some idea, but cannot fathom; they remain a puzzle to science, sometimes presenting the greatest difficulties. For instance, ether, gravitation, electricity, the nature of motion, and so on.

The noted physicist _J. J. Thomson_ says: "Gravitation is the secret of secrets. But the very same holds good of all molecular forces, of magnetism, electricity, etc. There are in animated nature even more things we cannot understand. We could say that of the processes of living organisms we understand practically nothing. Our knowledge of indigestion, of propagation, of instinct, is so small that we can almost say it is limited to the enumeration of them. What we do know and understand is not one thousandth part of what would be necessary for a knowledge in any degree complete. 'If we raise an arm,' says _Pasteur_, 'or put our teeth in action, we do something that no one can explain.' "

Theology and Progress.

With a very superficial conception of theology we might easily arrive at the opinion that it lacks a characteristic of science, which, in our time especially, is insisted upon, namely, progress. For it must adhere to dogmas and not go beyond them. Hence, seemingly, there is nothing to do for theology but to transmit unchangeable truths, perhaps in different aspects, but nevertheless the same truths.

It must be admitted that one kind of progress is barred in theology, as also in other sciences; to wit, the progress of incessant remodelling and reshaping, the continuous tearing down of the old facts, the eternal search after truth without ever gaining its possession.

This is often the progress demanded. "The new tuition," it is said, "starts from the premise that the truth is to be searched for" (_Paulsen_). "Science is not a perfected doctrine, but a research, ever to be revised" (_Harnack_). It is particularly demanded of theology that it procure a FURTHER DEVELOPMENT OF CHRISTIANITY, and subst.i.tute for it thoughts which modern age has adopted and which it calls scientific thinking. "There remains the task," they say, "of expressing faith and its objects so as to coincide with the conception formed by scientific thinking of the natural and historical reality" (_Paulsen_). Hence miracles, the divinity of Christ, and mysteries of any kind, must be eliminated; even the notion of a personal G.o.d will have to be changed to a pantheistic notion: "After the great revolution in our cosmic theories we can no longer think of G.o.d, the eternal holy Will that we revere as First Cause of all things, as the 'first mover'

throning outside and above the universe, as _Aristotle_ and _Thomas_ did" (_Paulsen_).

Such a progress is impossible in theology, at least in Catholic theology, and in any other that still aims to be the theology of the Christian, revealed religion. It cannot be expected from theology, nor from any other science, that it will degrade itself to a fashionable science, that takes for its level not truth but the variable imperatives and moods of the times, and, dest.i.tute of character, changes with each varying fashion. The science of faith cannot a.s.sume this position, so much the less as it must be aware that its truths often clash with the inclinations of the human heart, and that its vocation is to lift up mankind, not to let itself be dragged down. This kind of progress therefore is barred. This, indeed, is not progress, but a hopeless wavering from pillar to post, a building and tearing down, acquiring without permanent possession, searching without finding.

_True progress_ can be shown in theology as in any other science.

The _possibility_ of progress is manifest, particularly, in Church-history, in the biblical and pastoral sciences: they are closely related to the profane-historical, philological, social, and juridical branches of science, hence theology shares in their progress. It would seem that dogmatics would have to forego progress. Its progress certainly cannot consist in changing the revealed doctrines, nor in interpreting differently in the course of times the formulas of creed; here the rule is, _veritas Domini manet in aeternum_. The development of dogmatic knowledge consists rather in the following: the revealed truths are in the course of the centuries more and more clearly perceived and more sharply circ.u.mscribed, more surely demonstrated, more and more extensively appreciated in their connections, relations, and deductions. The sources of Divine Revelation flow the richer the more they are drawn from; their truths are so substantial, so abundant in relation to knowledge and life, that, the more research advances, the less it reaches its limit. "No one gets nearer to the realization of truth than he who perceives that in divine things, no matter how far he progresses, there remains always something more to be examined" (_Leo the Great_).

Consider the progress in mathematics. No one will say the mathematician is doomed to stagnation because he cannot change the multiplication table or the geometrical propositions. The increasing mathematical literature, with its big volumes, contradicts this notion: but its growth of knowledge is not the zigzag progress of restless to and fro, it is the solid progress from the seed to the plant.

As early as the fifth century _St. Vincent_ of Lerin described the progress in dogmatical knowledge: "Sed forsitan dicet aliquis: Nullusne ergo in Ecclesia Christi profectus habebitur religionis?

Habeatur plane et maximus. Nam quis ille est tam invidus hominibus, tam exosus Deo, qui istud prohibere conetur? Sed ita tamen, ut vere profectus sit ille fidei, non permutatio. Siquidem ad profectum pertinet, ut in semetipsum quaeque res amplificetur; ad permutationem vero, ut aliquid ex alio in aliud transvertatur.

Crescat igitur oportet et multum vehementerque proficiat tam singulorum quam omnium, tam unius hominis, quam totius Ecclesiae, aetatum ac saeculorum gradibus, intelligentia, scientia, sapientia, sed in suo duntaxat genere, in eodem scilicet dogmate, eodem sensu eademque sententia.... Quodeunque igitur in hac Ecclesiae Dei agricultura fide Patrum satum est, hoc idem filiorem industria decet excolatur et observetur, hoc idem floreat et maturescat, hoc idem proficiat et perficiatur. Fas est etenim, ut prisca illa coelestis philosophiae dogmata processu temporis excurentur, limentur, poliantur, sed nefas est, ut commutentur, nefas, ut detruncentur, ut mutilentur."

The _proof for the actual progress_ of theology is furnished by its history. It shows how theology has gradually grown from the first seed of the divine Word, placed by the hand of G.o.d's Son into the soil of humanity, until it became a great tree, rich in branches and leaves. The holiest men of the Christian centuries, equipped with the choicest mental forces, enlightened by the light of grace, have worked on its growth; toiling and praying, they filled libraries with their books.

It is not our intention to outline here a sketch of this development. A few hints may suffice. Hardly had the faith taken root in the civilized nations of the old times when researches were begun. A long list of Holy Fathers and ecclesiastical authors were the bearers of the first development. Drawing upon Greek philosophy in aid and to deepen their thought in the mental battle against the ancient pagan view of the world, against Judaism and heresy, they elucidated more and more the tenets of faith and morals, and endeavoured to draw ever more fully from their spiritual contents. We encounter among the shining host men like _Tertullian_, _Cyprian_, _Clement of Alexandria_, _Origines_, _Cyril of Jerusalem_, _Basil_, _Gregory of Nyssa_, and many others, up to the powerful dogmatist of the old time, _Augustine_, who treated scientifically and often extensively the great dogmas of faith. Truly a voluminous theological literature with a plethora of genius and truth. The great edition of the Greek and Latin Fathers by _Migne_ numbers 382 volumes in quarto, each of 1,500 pages or more in close print. Comparing with these 382 volumes the modest book of the Bible, which had been their foremost source, the progress of these centuries becomes manifest.

Soon the way was broken for systematizing the tenets of the faith, especially by _St. John Damascene_ (eighth century). Scholasticism completed the work: it created a systematical whole and connected theology and philosophy, especially the Aristotelian, into a harmonious union. Its pioneers were _St. Anselm_ and still more _Petrus Lombard_ (died 1160). Then, in the Middle Ages, when universities began to flourish, there followed the great theologians _Alexander of Hales_, _Bonaventure_, _Albert the Great_, _Scotus_, and chief of all _Thomas of Aquin_ (died 1274), in whom scholasticism reached its perfection, and undeniably one of the greatest minds known in the history of science; distinguished by an astonishing prolificness, still more by a wealth and depth of thought combined with the greatest simplicity and lucidity in presenting truths, he will for ever remain unapproachable. The decline of scholasticism during the fourteenth and fifteenth centuries was followed by a new bloom, when the life of the Church, rejuvenated by the Council of Trent, gave birth to new forces in theology. The mighty tomes of men like _Suarez_, _Lugo_, _Gregory of Valencia_, _Ruiz_, _Banez_, _Billuart_, and others joined the volumes of their predecessors and continued their work. At the same time the various departments of the science were branching off more and more, and became independent.

_M. Ca.n.u.s_ created the theory of theological cognition as an introduction to dogmatics, _Bellarmin_ and _Th. Stapleton_ founded the newer controversial theology. Moral Theology became in the sixteenth century a separate science and was developed by men like _Lugo_, _Laymann_, _Busembaum_, _Alphons of Liguori_. Similarly a new period of research began in the biblical sciences. Not that the first foundations were laid at that time; there had been _Origines_, who had become the founder of biblical text criticism by his "Hexapla"; the Antioch school of exegetes, _Chrysostomus_, _Hilarius_, and especially _Jerome_. But it was fostered with renewed zeal. The great Antwerp and Paris polyglots furnished aids, men like _Maldonatus_, _Salmeron_, _Toletus_, _Cornelius_, _a Lapide_, wrote their exegetic works. To the seventeenth century belongs the creation of the propaedeutics, by _Richard Simon_ and _Bernard Lami_. The monumental work, "Cursus sacrae scripturae"

(since 1885), containing so far thirty-six volumes, demonstrates, among other things, that there has been in recent years no standstill in the research in Holy Writ. In the province of ecclesiastical history, too, with its branches and auxiliary sciences, new life was awakened at that time. In the sixteenth century, when the defence of the creed by the witnesses of a former age became urgent, patristics and history of dogma enjoyed their first rise. _Petavius_ was prominently connected with them.

How these sciences have been fostered in the nineteenth century is indicated by the names of _Mai_, _De Rossi_, _Hergenroether_, _Hefele_, _Pastor_. There remains to be mentioned the gradual establishment of the science of Canon law, of the pastoral-theological departments which have attained an independent position since the close of the eighteenth century, and since then produced a voluminous literature. The fear of a standstill in theological research seems unwarranted in the light of its history. The errors of the present time will prevent a standstill. The more vehement the attacks by natural science and philosophy, by philology and archaeology, the more they seek to shake the foundations of the Christian religion, the stronger theology must grow by the combat. The solid progress of our times in knowledge and methodics will not remain without influence; nor can the empirical, the historical-critical method, the theory of evolution, and so on, fail to exert their stimulating influence upon theology.

The progress that Catholic theology has made since the days of the Fathers, the vast amount of mental work it has performed, is perhaps made most clear by a glance at the "Nomenclator literarius theologiae catholicae," by _H. Hurter_ (2d ed., 3 vols.; the 3d ed. is in 6 vols., 5 being ready). It gives in concise briefness the biographical data and the more important works of Catholic theologians of greater repute. Counting the names there presented, we find not less than 3,900 from 1109 to 1563; about 2,900 from 1564 to 1663; about 3,900 between 1664 and 1763; finally, from 1764 to 1894 about 4,000 theological authors; hence in the period from 1109 to 1894 nearly 14,700 theologians. That these 14,700 scientists-and their number is not exhausted by this figure-should have written their works without offering in them any new knowledge, would surely be a bold a.s.sertion! In addition consider the long rows of tomes which some of them wrote. Perhaps it would not be wholly amiss to refer to the restless zeal of many of them, as recorded by their biographers. _Baronius_ (died 1607) could truthfully a.s.sert before his death, that for thirty years he had never had sufficient sleep; he usually slept only four or five hours. _Pierre Halloix_ (died 1656) likewise was content with four or five hours of rest. _Dionysius Sanmartha.n.u.s_ (died 1725) gave only four hours to sleep and devoted less than half an hour daily to recreation; likewise _Fr. Combefis_ (died 1679), during the last forty years of his life. _A. Fr. Orsi_ (died 1761) contented himself with three or four hours of sleep; _Fr. Clement_ (died 1793) and _H. Oberrauch_ (died 1808) are said to have slept but two hours daily. _J. Caramuel de Lobkowicz_ (died 1682) persevered for fourteen hours every day at his books; _Chr. Lupus_ (died 1681) even for fifteen hours daily. The theologian _Lessius_ is characterized by "_Parcissimus erat temporis, laboris pertinax_"; the same holds good of hundreds of others of these men.

A science, enumerating its disciples by so many thousands, with the greatest intellects among its workers, which has commanded so much zeal and work for centuries, should be safe from the reproach of having back of it a history of stagnation.

Theology and Freedom of Science.

To many it seems obvious that theology lacks at least the other predicate of science, freedom; because it is bound to dogmas and ecclesiastical authorities, at least Catholic theology is.

Although this claim is pressed persistently and with confidence, we may dispose of it very briefly. The freedom missed in theology, and demanded in its behalf, is none other than the liberal freedom of science, the nature of which we have had sufficiently long under the searchlight, so that there remains nothing to be added. We have proved sufficiently that this freedom is not a freedom from unnatural fetters, but a dissolute subjectivism, that claims the right not to be bound to any unchangeable, religious truths. We admit that the Catholic theology does not possess _THIS_ freedom. Convinced of the truth of the doctrines established by divine testimony, and by the infallible voice of the Church, theology sees not freedom but a sin against truth in the license to a.s.sert the contrary of what it has recognized as the truth.

There is but one freedom which science may claim: it is freedom from hindrance in reaching the truth in its legitimate domain. If this truth is transmitted to science infallibly, by the highest instance of wisdom-and of this every theologian is convinced-how can science be said to be hindered thereby in attaining the truth? Restrained it is, but only by truth: truth, however, can only be a barrier to license, but not to precious freedom. This restraint theology shares with the rest of the sciences. The physicist is tied to the facts brought forth by the experiments of his laboratory; the astronomer is tied to the results reported to him by the instruments of his observatory, the historian is tied to the events disclosed by his sources. Moreover, all sciences are tied to their methods. In this way, and in no other way, the theologian, too, is tied to the facts given him by Revelation, and to his method.

Every science has its own method. The astronomer gains his facts by observation and calculation, the mathematician arrives at his facts by calculation and study; the historian, by human testimony; the theologian, however, by divine testimony, at least as to fundamental truths. That they are transmitted to him not by his personal study, but by external testimony, does not matter; the historian too draws from such sources. Nor can theological knowledge be less certain because vouched for by divine authority: it makes it the more certain. Or is there no divine authority, and can there be none? This is exactly the silent presumption, which is the basis of the charge against theology. But where is the proof for it?

It can only be demonstrated by denying the existence of a supermundane G.o.d; for, if there is an Almighty G.o.d, there can be no doubt that He can give a Revelation and demand belief.

Perhaps it may be said further, the theologian is not permitted to doubt his doctrines, hence he is prohibited from examining them; he surely cannot be _unprepossessed_.

We can refer to what we have previously said. Unprepossession demands but one thing, namely, not to a.s.sume something as true and certain that is false or unproved; it demands strong proofs for anything that needs proof.

We may safely a.s.sert that there is no other science more exacting in this respect than Catholic theology, both of the present and of the past. It has not a single position that is not incessantly tested by attacks as to its tenability. Any one not unacquainted with theology, who knows the works of _St. Thomas_ and of the later theologians, with their exact methods of thinking, who observes the conscientious work in Catholic biblical-exegetic, historical-critical field, must be convinced of the serious atmosphere of truth prevailing here. Unprepossession does not demand to doubt, time and again, that which has been positively proved, to rediscover it by new research. Positive facts are no longer a subject for research; in their case research has fully achieved its end. Methodical doubt, proper in scientific examination, is proper also in regard to religious truths.

Furthermore, the lat.i.tude of the theologian is much larger than presumed by those who derive their information solely from modern a.s.sertions about dogmatic bondage. One may safely a.s.sert that the freedom of movement of the mathematician is more limited by his principles, his train of thought more sharply prescribed, than is the case with the theologian. Of course the theologian is bound by everything he finds infallibly established directly by revelation and by the authority of the Church; or indirectly by the concurring teaching of the Fathers or the theologians; he is bound also by non-infallible decisions, especially those of congregations, though not absolutely and not irrevocably.
