Understanding Faith and Reason
(Excerpted by Prof. W. Nierras, Ph.D from the Catechism of the Catholic Church and the Encyclical of Saint Pope John Paul II Fides et Ratio, 16 August 2021)
From the Catechism of the Catholic Church, no. 159
159 Faith and science: "Though faith is above reason, there can never be any real discrepancy between faith and reason. Since the same God who reveals mysteries and infuses faith has bestowed the light of reason on the human mind, God cannot deny himself, nor can truth ever contradict truth." "Consequently, methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. the humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are." From Encyclical Letter Fides Et Ratio, Chapter IV, Saint Pope John Paul II, 14 September 1998 Important moments in the encounter of faith and reason 36. The Acts of the Apostles provides evidence that Christian proclamation was engaged from the very first with the philosophical currents of the time. In Athens, we read, Saint Paul entered into discussion with “certain Epicurean and Stoic philosophers” (17:18); and exegetical analysis of his speech at the Areopagus has revealed frequent allusions to popular beliefs deriving for the most part from Stoicism. This is by no means accidental. If pagans were to understand them, the first Christians could not refer only to “Moses and the prophets” when they spoke. They had to point as well to natural knowledge of God and to the voice of conscience in every human being (cf. Rom 1:19-21; 2:14-15; Acts 14:16-17). Since in pagan religion this natural knowledge had lapsed into idolatry (cf. Rom 1:21-32), the Apostle judged it wiser in his speech to make the link with the thinking of the philosophers, who had always set in opposition to the myths and mystery cults notions more respectful of divine transcendence. One of the major concerns of classical philosophy was to purify human notions of God of mythological elements. We know that Greek religion, like most cosmic religions, was polytheistic, even to the point of divinizing natural things and phenomena. Human attempts to understand the origin of the gods and hence the origin of the universe find their earliest expression in poetry; and the theogonies remain the first evidence of this human search. But it was the task of the fathers of philosophy to bring to light the link between reason and religion. As they broadened their view to include universal principles, they no longer rested content with the ancient myths, but wanted to provide a rational foundation for their belief in the divinity… 38. Christianity's engagement with philosophy was therefore neither straight-forward nor immediate. The practice of philosophy and attendance at philosophical schools seemed to the first Christians more of a disturbance than an opportunity. For them, the first and most urgent task was the proclamation of the Risen Christ by way of a personal encounter which would bring the listener to conversion of heart and the request for Baptism. But that does not mean that they ignored the task of deepening the understanding of faith and its motivations… Since access to the truth enables access to God, it must be denied to none. There are many paths which lead to truth, but since Christian truth has a salvific value, any one of these paths may be taken, as long as it leads to the final goal, that is to the Revelation of Jesus Christ. A pioneer of positive engagement with philosophical thinking—albeit with cautious discernment—was Saint Justin. Although he continued to hold Greek philosophy in high esteem after his conversion, Justin claimed with power and clarity that he had found in Christianity “the only sure and profitable philosophy”. Similarly, Clement of Alexandria called the Gospel “the true philosophy”, and he understood philosophy, like the Mosaic Law, as instruction which prepared for Christian faith and paved the way for the Gospel... |

39. It is clear from history, then, that Christian thinkers were critical in adopting philosophical thought. Among the early examples of this, Origen is certainly outstanding. In countering the attacks launched by the philosopher Celsus, Origen adopts Platonic philosophy to shape his argument and mount his reply. Assuming many elements of Platonic thought, he begins to construct an early form of Christian theology. The name “theology” itself, together with the idea of theology as rational discourse about God, had to this point been tied to its Greek origins. In Aristotelian philosophy, for example, the name signified the noblest part and the true summit of philosophical discourse. But in the light of Christian Revelation what had signified a generic doctrine about the gods assumed a wholly new meaning, signifying now the reflection undertaken by the believer in order to express the true doctrine about God. As it developed, this new Christian thought made use of philosophy, but at the same time tended to distinguish itself clearly from philosophy…
41. The ways in which the Fathers of East and West engaged the philosophical schools were, therefore, quite different. This does not mean that they identified the content of their message with the systems to which they referred. Consider Tertullian's question: “What does Athens have in common with Jerusalem? The Academy with the Church?”. This clearly indicates the critical consciousness with which Christian thinkers from the first confronted the problem of the relationship between faith and philosophy, viewing it comprehensively with both its positive aspects and its limitations. They were not naive thinkers. Precisely because they were intense in living faith's content they were able to reach the deepest forms of speculation. It is therefore minimalizing and mistaken to restrict their work simply to the transposition of the truths of faith into philosophical categories. They did much more. In fact they succeeded in disclosing completely all that remained implicit and preliminary in the thinking of the great philosophers of antiquity. As I have noted, theirs was the task of showing how reason, freed from external constraints, could find its way out of the blind alley of myth and open itself to the transcendent in a more appropriate way. Purified and rightly tuned, therefore, reason could rise to the higher planes of thought, providing a solid foundation for the perception of being, of the transcendent and of the absolute. It is here that we see the originality of what the Fathers accomplished. They fully welcomed reason which was open to the absolute, and they infused it with the richness drawn from Revelation. This was more than a meeting of cultures, with one culture perhaps succumbing to the fascination of the other. It happened rather in the depths of human souls, and it was a meeting of creature and Creator. Surpassing the goal towards which it unwittingly tended by dint of its nature, reason attained the supreme good and ultimate truth in the person of the Word made flesh. Faced with the various philosophies, the Fathers were not afraid to acknowledge those elements in them that were consonant with Revelation and those that were not. Recognition of the points of convergence did not blind them to the points of divergence. 42. In Scholastic theology, the role of philosophically trained reason becomes even more conspicuous under the impulse of Saint Anselm's interpretation of the intellectus fidei. For the saintly Archbishop of Canterbury the priority of faith is not in competition with the search which is proper to reason. Reason in fact is not asked to pass judgement on the contents of faith, something of which it would be incapable, since this is not its function. Its function is rather to find meaning, to discover explanations which might allow everyone to come to a certain understanding of the contents of faith. Saint Anselm underscores the fact that the intellect must seek that which it loves: the more it loves, the more it desires to know. Whoever lives for the truth is reaching for a form of knowledge which is fired more and more with love for what it knows, while having to admit that it has not yet attained what it desires: “To see you was I conceived; and I have yet to conceive that for which I was conceived (Ad te videndum factus sum; et nondum feci propter quod factus sum)”. The desire for truth, therefore, spurs reason always to go further; indeed, it is as if reason were overwhelmed to see that it can always go beyond what it has already achieved. It is at this point, though, that reason can learn where its path will lead in the end: “I think that whoever investigates something incomprehensible should be satisfied if, by way of reasoning, he reaches a quite certain perception of its reality, even if his intellect cannot penetrate its mode of being... But is there anything so incomprehensible and ineffable as that which is above all things? Therefore, if that which until now has been a matter of debate concerning the highest essence has been established on the basis of due reasoning, then the foundation of one's certainty is not shaken in the least if the intellect cannot penetrate it in a way that allows clear formulation. If prior thought has concluded rationally that one cannot comprehend (rationabiliter comprehendit incomprehensibile esse) how supernal wisdom knows its own accomplishments..., who then will explain how this same wisdom, of which the human being can know nothing or next to nothing, is to be known and expressed?”. The fundamental harmony between the knowledge of faith and the knowledge of philosophy is once again confirmed. Faith asks that its object be understood with the help of reason; and at the summit of its searching reason acknowledges that it cannot do without what faith presents. The enduring originality of the thought of Saint Thomas Aquinas 43. A quite special place in this long development belongs to Saint Thomas, not only because of what he taught but also because of the dialogue which he undertook with the Arab and Jewish thought of his time. In an age when Christian thinkers were rediscovering the treasures of ancient philosophy, and more particularly of Aristotle, Thomas had the great merit of giving pride of place to the harmony which exists between faith and reason. Both the light of reason and the light of faith come from God, he argued; hence there can be no contradiction between them. More radically, Thomas recognized that nature, philosophy's proper concern, could contribute to the understanding of divine Revelation. Faith therefore has no fear of reason, but seeks it out and has trust in it. Just as grace builds on nature and brings it to fulfilment, so faith builds upon and perfects reason. Illumined by faith, reason is set free from the fragility and limitations deriving from the disobedience of sin and finds the strength required to rise to the knowledge of the Triune God. Although he made much of the supernatural character of faith, the Angelic Doctor did not overlook the importance of its reasonableness; indeed, he was able to plumb the depths and explain the meaning of this reasonableness. Faith is in a sense an “exercise of thought”; and human reason is neither annulled nor debased in assenting to the contents of faith, which are in any case attained by way of free and informed choice. This is why the Church has been justified in consistently proposing Saint Thomas as a master of thought and a model of the right way to do theology… 44. Another of the great insights of Saint Thomas was his perception of the role of the Holy Spirit in the process by which knowledge matures into wisdom. From the first pages of his Summa Theologiae, Aquinas was keen to show the primacy of the wisdom which is the gift of the Holy Spirit and which opens the way to a knowledge of divine realities. His theology allows us to understand what is distinctive of wisdom in its close link with faith and knowledge of the divine. This wisdom comes to know by way of connaturality; it presupposes faith and eventually formulates its right judgement on the basis of the truth of faith itself: “The wisdom named among the gifts of the Holy Spirit is distinct from the wisdom found among the intellectual virtues. This second wisdom is acquired through study, but the first 'comes from on high', as Saint James puts it. This also distinguishes it from faith, since faith accepts divine truth as it is. But the gift of wisdom enables judgement according to divine truth”. Yet the priority accorded this wisdom does not lead the Angelic Doctor to overlook the presence of two other complementary forms of wisdom--philosophical wisdom, which is based upon the capacity of the intellect, for all its natural limitations, to explore reality, and theological wisdom, which is based upon Revelation and which explores the contents of faith, entering the very mystery of God. Profoundly convinced that “whatever its source, truth is of the Holy Spirit” (omne verum a quocumque dicatur a Spiritu Sancto est) Saint Thomas was impartial in his love of truth. He sought truth wherever it might be found and gave consummate demonstration of its universality. In him, the Church's Magisterium has seen and recognized the passion for truth; and, precisely because it stays consistently within the horizon of universal, objective and transcendent truth, his thought scales “heights unthinkable to human intelligence”. Rightly, then, he may be called an “apostle of the truth”. Looking unreservedly to truth, the realism of Thomas could recognize the objectivity of truth and produce not merely a philosophy of “what seems to be” but a philosophy of “what is”. The drama of the separation of faith and reason 45. With the rise of the first universities, theology came more directly into contact with other forms of learning and scientific research. Although they insisted upon the organic link between theology and philosophy, Saint Albert the Great and Saint Thomas were the first to recognize the autonomy which philosophy and the sciences needed if they were to perform well in their respective fields of research. From the late Medieval period onwards, however, the legitimate distinction between the two forms of learning became more and more a fateful separation. As a result of the exaggerated rationalism of certain thinkers, positions grew more radical and there emerged eventually a philosophy which was separate from and absolutely independent of the contents of faith. Another of the many consequences of this separation was an ever deeper mistrust with regard to reason itself. In a spirit both sceptical and agnostic, some began to voice a general mistrust, which led some to focus more on faith and others to deny its rationality altogether. In short, what for Patristic and Medieval thought was in both theory and practice a profound unity, producing knowledge capable of reaching the highest forms of speculation, was destroyed by systems which espoused the cause of rational knowledge sundered from faith and meant to take the place of faith. |

46… In the field of scientific research, a positivistic mentality took hold which not only abandoned the Christian vision of the world, but more especially rejected every appeal to a metaphysical or moral vision. It follows that certain scientists, lacking any ethical point of reference, are in danger of putting at the centre of their concerns something other than the human person and the entirety of the person's life. Further still, some of these, sensing the opportunities of technological progress, seem to succumb not only to a market-based logic, but also to the temptation of a quasi-divine power over nature and even over the human being. As a result of the crisis of rationalism, what has appeared finally is nihilism. As a philosophy of nothingness, it has a certain attraction for people of our time. Its adherents claim that the search is an end in itself, without any hope or possibility of ever attaining the goal of truth. In the nihilist interpretation, life is no more than an occasion for sensations and experiences in which the ephemeral has pride of place. Nihilism is at the root of the widespread mentality which claims that a definitive commitment should no longer be made, because everything is fleeting and provisional.
47. It should also be borne in mind that the role of philosophy itself has changed in modern culture. From universal wisdom and learning, it has been gradually reduced to one of the many fields of human knowing; indeed in some ways it has been consigned to a wholly marginal role. Other forms of rationality have acquired an ever higher profile, making philosophical learning appear all the more peripheral. These forms of rationality are directed not towards the contemplation of truth and the search for the ultimate goal and meaning of life; but instead, as “instrumental reason”, they are directed—actually or potentially—towards the promotion of utilitarian ends, towards enjoyment or power…
48. This rapid survey of the history of philosophy, then, reveals a growing separation between faith and philosophical reason. Yet closer scrutiny shows that even in the philosophical thinking of those who helped drive faith and reason further apart there are found at times precious and seminal insights which, if pursued and developed with mind and heart rightly tuned, can lead to the discovery of truth's way. Such insights are found, for instance, in penetrating analyses of perception and experience, of the imaginary and the unconscious, of personhood and intersubjectivity, of freedom and values, of time and history. The theme of death as well can become for all thinkers an incisive appeal to seek within themselves the true meaning of their own life. But this does not mean that the link between faith and reason as it now stands does not need to be carefully examined, because each without the other is impoverished and enfeebled. Deprived of what Revelation offers, reason has taken side-tracks which expose it to the danger of losing sight of its final goal. Deprived of reason, faith has stressed feeling and experience, and so run the risk of no longer being a universal proposition. It is an illusion to think that faith, tied to weak reasoning, might be more penetrating; on the contrary, faith then runs the grave risk of withering into myth or superstition. By the same token, reason which is unrelated to an adult faith is not prompted to turn its gaze to the newness and radicality of being…
Current tasks for theology
92. As an understanding of Revelation, theology has always had to respond in different historical moments to the demands of different cultures, in order then to mediate the content of faith to those cultures in a coherent and conceptually clear way. Today, too, theology faces a dual task. On the one hand, it must be increasingly committed to the task entrusted to it by the Second Vatican Council, the task of renewing its specific methods in order to serve evangelization more effectively… On the other hand, theology must look to the ultimate truth which Revelation entrusts to it, never content to stop short of that goal. Theologians should remember that their work corresponds “to a dynamism found in the faith itself” and that the proper object of their enquiry is “the Truth which is the living God and his plan for salvation revealed in Jesus Christ”. This task, which is theology's prime concern, challenges philosophy as well. The array of problems which today need to be tackled demands a joint effort—approached, it is true, with different methods—so that the truth may once again be known and expressed. The Truth, which is Christ, imposes itself as an all-embracing authority which holds out to theology and philosophy alike the prospect of support, stimulation and increase (cf. Eph 4:15)…
93. The chief purpose of theology is to provide an understanding of Revelation and the content of faith. The very heart of theological enquiry will thus be the contemplation of the mystery of the Triune God. The approach to this mystery begins with reflection upon the mystery of the Incarnation of the Son of God: his coming as man, his going to his Passion and Death, a mystery issuing into his glorious Resurrection and Ascension to the right hand of the Father, whence he would send the Spirit of truth to bring his Church to birth and give her growth. From this vantage-point, the prime commitment of theology is seen to be the understanding of God's kenosis, a grand and mysterious truth for the human mind, which finds it inconceivable that suffering and death can express a love which gives itself and seeks nothing in return. In this light, a careful analysis of texts emerges as a basic and urgent need: first the texts of Scripture, and then those which express the Church's living Tradition. On this score, some problems have emerged in recent times, problems which are only partially new; and a coherent solution to them will not be found without philosophy's contribution.
94. An initial problem is that of the relationship between meaning and truth. Like every other text, the sources which the theologian interprets primarily transmit a meaning which needs to be grasped and explained. This meaning presents itself as the truth about God which God himself communicates through the sacred text. Human language thus embodies the language of God, who communicates his own truth with that wonderful “condescension” which mirrors the logic of the Incarnation. In interpreting the sources of Revelation, then, the theologian needs to ask what is the deep and authentic truth which the texts wish to communicate, even within the limits of language…
97. The interpretation of sources is a vital task for theology; but another still more delicate and demanding task is the understanding of revealed truth, or the articulation of the intellectus fidei. The intellectus fidei, as I have noted, demands the contribution of a philosophy of being which first of all would enable dogmatic theology to perform its functions appropriately. The dogmatic pragmatism of the early years of this century, which viewed the truths of faith as nothing more than rules of conduct, has already been refuted and rejected; but the temptation always remains of understanding these truths in purely functional terms. This leads only to an approach which is inadequate, reductive and superficial at the level of speculation. A Christology, for example, which proceeded solely “from below”, as is said nowadays, or an ecclesiology developed solely on the model of civil society, would be hard pressed to avoid the danger of such reductionism.
If the intellectus fidei wishes to integrate all the wealth of the theological tradition, it must turn to the philosophy of being, which should be able to propose anew the problem of being—and this in harmony with the demands and insights of the entire philosophical tradition, including philosophy of more recent times, without lapsing into sterile repetition of antiquated formulas. Set within the Christian metaphysical tradition, the philosophy of being is a dynamic philosophy which views reality in its ontological, causal and communicative structures. It is strong and enduring because it is based upon the very act of being itself, which allows a full and comprehensive openness to reality as a whole, surpassing every limit in order to reach the One who brings all things to fulfilment. In theology, which draws its principles from Revelation as a new source of knowledge, this perspective is confirmed by the intimate relationship which exists between faith and metaphysical reasoning.
98. These considerations apply equally to moral theology. It is no less urgent that philosophy be recovered at the point where the understanding of faith is linked to the moral life of believers. Faced with contemporary challenges in the social, economic, political and scientific fields, the ethical conscience of people is disoriented. In the Encyclical Letter Veritatis Splendor, I wrote that many of the problems of the contemporary world stem from a crisis of truth. I noted that “once the idea of a universal truth about the good, knowable by human reason, is lost, inevitably the notion of conscience also changes. Conscience is no longer considered in its prime reality as an act of a person's intelligence, the function of which is to apply the universal knowledge of the good in a specific situation and thus to express a judgment about the right conduct to be chosen here and now. Instead, there is a tendency to grant to the individual conscience the prerogative of independently determining the criteria of good and evil and then acting accordingly. Such an outlook is quite congenial to an individualist ethic, wherein each individual is faced with his own truth different from the truth of others”…
99. Theological work in the Church is first of all at the service of the proclamation of the faith and of catechesis. Proclamation or kerygma is a call to conversion, announcing the truth of Christ, which reaches its summit in his Paschal Mystery: for only in Christ is it possible to know the fullness of the truth which saves (cf. Acts 4:12; 1 Tm 2:4-6). In this respect, it is easy to see why, in addition to theology, reference to catechesis is also important, since catechesis has philosophical implications which must be explored more deeply in the light of faith. The teaching imparted in catechesis helps to form the person. As a mode of linguistic communication, catechesis must present the Church's doctrine in its integrity, demonstrating its link with the life of the faithful. The result is a unique bond between teaching and living which is otherwise unattainable, since what is communicated in catechesis is not a body of conceptual truths, but the mystery of the living God. Philosophical enquiry can help greatly to clarify the relationship between truth and life, between event and doctrinal truth, and above all between transcendent truth and humanly comprehensible language. This involves a reciprocity between the theological disciplines and the insights drawn from the various strands of philosophy; and such a reciprocity can prove genuinely fruitful for the communication and deeper understanding of the faith.
47. It should also be borne in mind that the role of philosophy itself has changed in modern culture. From universal wisdom and learning, it has been gradually reduced to one of the many fields of human knowing; indeed in some ways it has been consigned to a wholly marginal role. Other forms of rationality have acquired an ever higher profile, making philosophical learning appear all the more peripheral.
