13- Reason before the mystery
13. It should nonetheless be kept in mind that Revelation remains charged with mystery. It is true that Jesus, with his entire life, revealed the countenance of the Father, for he came to teach the secret things of God.(13) But our vision of the face of God is always fragmentary and impaired by the limits of our understanding. Faith alone makes it possible to penetrate the mystery in a way that allows us to understand it coherently.
The Council teaches that the obedience of faith must be given to God who reveals himself.(14) This brief but dense statement points to a fundamental truth of Christianity. Faith is said first to be an obedient response to God. This implies that God be acknowledged in his divinity, transcendence and supreme freedom. By the authority of his absolute transcendence, God who makes himself known is also the source of the credibility of what he reveals. By faith, men and women give their assent to this divine testimony. This means that they acknowledge fully and integrally the truth of what is revealed because it is God himself who is the guarantor of that truth. They can make no claim upon this truth which comes to them as gift and which, set within the context of interpersonal communication, urges reason to be open to it and to embrace its profound meaning. This is why the Church has always considered the act of entrusting oneself to God to be a moment of fundamental decision which engages the whole person. In that act, the intellect and the will display their spiritual nature, enabling the subject to act in a way which realizes personal freedom to the full.(15) It is not just that freedom is part of the act of faith: it is absolutely required. Indeed, it is faith that allows individuals to give consummate expression to their own freedom. Put differently, freedom is not realized in decisions made against God. For how could it be an exercise of true freedom to refuse to be open to the very reality which enables our self-realization? Men and women can accomplish no more important act in their lives than the act of faith; it is here that freedom reaches the certainty of truth and chooses to live in that truth.
To assist reason in its effort to understand the mystery there are the signs which Revelation itself presents. These serve to lead the search for truth to new depths, enabling the mind in its autonomous exploration to penetrate within the mystery by use of reason's own methods, of which it is rightly jealous. Yet these signs also urge reason to look beyond their status as signs in order to grasp the deeper meaning which they bear. They contain a hidden truth to which the mind is drawn and which it cannot ignore without destroying the very signs which it is given.
In a sense, then, we return to the sacramental character of Revelation and especially to the sign of the Eucharist, in which the indissoluble unity between the signifier and signified makes it possible to grasp the depths of the mystery. In the Eucharist, Christ is truly present and alive, working through his Spirit; yet, as Saint Thomas said so well, what you neither see nor grasp, faith confirms for you, leaving nature far behind; a sign it is that now appears, hiding in mystery realities sublime.(16) He is echoed by the philosopher Pascal: Just as Jesus Christ went unrecognized among men, so does his truth appear without external difference among common modes of thought. So too does the Eucharist remain among common bread.(17)
In short, the knowledge proper to faith does not destroy the mystery; it only reveals it the more, showing how necessary it is for people's lives: Christ the Lord in revealing the mystery of the Father and his love fully reveals man to himself and makes clear his supreme calling,(18) which is to share in the divine mystery of the life of the Trinity.(19)
14. From the teaching of the two Vatican Councils there also emerges a genuinely novel consideration for philosophical learning. Revelation has set within history a point of reference which cannot be ignored if the mystery of human life is to be known. Yet this knowledge refers back constantly to the mystery of God which the human mind cannot exhaust but can only receive and embrace in faith. Between these two poles, reason has its own specific field in which it can enquire and understand, restricted only by its finiteness before the infinite mystery of God.
Revelation therefore introduces into our history a universal and ultimate truth which stirs the human mind to ceaseless effort; indeed, it impels reason continually to extend the range of its knowledge until it senses that it has done all in its power, leaving no stone unturned. To assist our reflection on this point we have one of the most fruitful and important minds in human history, a point of reference for both philosophy and theology: Saint Anselm. In his Proslogion, the Archbishop of Canterbury puts it this way: Thinking of this problem frequently and intently, at times it seemed I was ready to grasp what I was seeking; at other times it eluded my thought completely, until finally, despairing of being able to find it, I wanted to abandon the search for something which was impossible to find. I wanted to rid myself of that thought because, by filling my mind, it distracted me from other problems from which I could gain some profit; but it would then present itself with ever greater insistence... Woe is me, one of the poor children of Eve, far from God, what did I set out to do and what have I accomplished? What was I aiming for and how far have I got? What did I aspire to and what did I long for?... O Lord, you are not only that than which nothing greater can be conceived (non solum es quo maius cogitari nequit), but you are greater than all that can be conceived (quiddam maius quam cogitari possit)... If you were not such, something greater than you could be thought, but this is impossible.(20)
15. The truth of Christian Revelation, found in Jesus of Nazareth, enables all men and women to embrace the mystery of their own life. As absolute truth, it summons human beings to be open to the transcendent, whilst respecting both their autonomy as creatures and their freedom. At this point the relationship between freedom and truth is complete, and we understand the full meaning of the Lord's words: You will know the truth, and the truth will make you free (Jn 8:32).
Christian Revelation is the true lodestar of men and women as they strive to make their way amid the pressures of an immanentist habit of mind and the constrictions of a technocratic logic. It is the ultimate possibility offered by God for the human being to know in all its fullness the seminal plan of love which began with creation. To those wishing to know the truth, if they can look beyond themselves and their own concerns, there is given the possibility of taking full and harmonious possession of their lives, precisely by following the path of truth. Here the words of the Book of Deuteronomy are pertinent: This commandment which I command you is not too hard for you, neither is it far off. It is not in heaven that you should say, 'Who will go up for us to heaven, and bring it to us, that we may hear it and do it?' Neither is it beyond the sea, that you should say, 'Who will go over the sea for us, and bring it to us, that we may hear and do it?' But the word is very near you; it is in your mouth and in your heart, that you can do it (30:11-14). This text finds an echo in the famous dictum of the holy philosopher and theologian Augustine: Do not wander far and wide but return into yourself. Deep within man there dwells the truth (Noli foras ire, in te ipsum redi. In interiore homine habitat veritas).(21)
These considerations prompt a first conclusion: the truth made known to us by Revelation is neither the product nor the consummation of an argument devised by human reason. It appears instead as something gratuitous, which itself stirs thought and seeks acceptance as an expression of love. This revealed truth is set within our history as an anticipation of that ultimate and definitive vision of God which is reserved for those who believe in him and seek him with a sincere heart. The ultimate purpose of personal existence, then, is the theme of philosophy and theology alike. For all their difference of method and content, both disciplines point to that path of life (Ps 16:11) which, as faith tells us, leads in the end to the full and lasting joy of the contemplation of the Triune God.
