" The Church has not built up the “Opus Dei” for the pleasure of forming beautiful symbols, choice language, and graceful, stately gestures, but she has done it—in so far as it is not completely devoted to the worship of God—for the sake of our desperate spiritual need. It is to give expression to the events of the Christian’s inner life: the assimilation, through the Holy Ghost, of the life of the creature to the life of God in Christ; the actual and genuine rebirth of the creature into a new existence; the development and nourishment of this life, its stretching forth from God in the Blessed Sacrament and the means of grace, towards God in prayer and sacrifice; and all this in the continual mystic renewal of Christ’s life in the course of the ecclesiastical year. The fulfillment of all these processes by the set forms of language, gesture, and instruments, their revelation, teaching, accomplishment and acceptance by the faithful, together constitute the liturgy. We see, then, that it is primarily concerned with reality, with the approach of a real creature to a real God, and with the profoundly real and serious matter of redemption. There is here no question of creating beauty, but of finding salvation for sin-stricken humanity. Here truth is at stake, and the fate of the soul, and real—yes, ultimately the only real—life. All this it is which must be revealed, expressed, sought after, found, and imparted by every possible means and method; and when this is accomplished, lo! it is turned into beauty. "

" It is obvious that the concept of truth has become suspect. Of course it is correct that is has been much abused. Intolerance and cruelty have occurred in the name of truth. To that extent people are afraid when someone says, "This is the truth", or even "I have the truth". We never have it, at best is has us. No one will dispute that one must be careful and cautious in claiming the truth. But simply to dismiss it as unattainable is really destructive.
(...) We must have the courage to dare to say: Yes, man must seek the truth; he is capable of truth. It goes without saying that truth requires criteria for verification and falsification. It must always be accompanied by tolerance, also. But then truth also points out to us those constant values which have made mankind great. That is why the humility to recognize the truth and to accept it as a standard has to be relearned and practiced again.
The truth comes to rule, not through violence, but rather through its own power; this is the central theme of John's Gospel: When brought before Pilate, Jesus professes that he himself is The Truth and the witness to the truth. He does not defend the truth with legions but rather makes it visible through his Passion and thereby also implements it. "

" Both capitalism and Marxism promised to point out the path for the creation of just structures, and they declared that these, once established, would function by themselves; they declared that not only would they have no need of any prior individual morality, but that they would promote a communal morality. And this ideological promise has been proved false. The facts have clearly demonstrated it. The Marxist system, where it found its way into government, not only left a sad heritage of economic and ecological destruction, but also a painful oppression of souls. And we can also see the same thing happening in the West, where the distance between rich and poor is growing constantly, and giving rise to a worrying degradation of personal dignity through drugs, alcohol and deceptive illusions of happiness.

" Whether it is Bach or Mozart that we hear in church, we have a sense in either case of what gloria Dei, the glory of God, means. The mystery of infinite beauty is there and enables us to experience the presence of God more truly and vividly than in many sermons. But there are already signs of danger to come. Subjective experience and passion are still held in check by the order of the musical universe, reflecting as it does the order of the divine creation itself. But there is already the threat of invasion by the virtuoso mentality, the vanity of technique, which is no longer the servant of the whole but wants to push itself to the fore. During the nineteenth century, the century of self-emancipating subjectivity, this led in many places to the obscuring of the sacred by the operatic. The dangers that had forced the Council of Trent to intervene were back again. In similar fashion, Pope Pius X tried to remove the operatic element from the liturgy and declared Gregorian chant and the great polyphony of the age of the Catholic Reformation (of which Palestrina was the outstanding representative) to be the standard for liturgical music. A clear distinction was made between liturgical music and religious music in general, just as visual art in the liturgy has to conform to different standards from those employed in religious art in general. Art in the liturgy has a very specific responsibility, and precisely as such does it serve as a wellspring of culture, which in the final analysis owes its existence to cult. "

" But first let me mention the second aid to understanding provided by science. We know today that in a physical experiment the observer himself enters into the experiment and only by doing so can arrive at a physical experience. This means that there is no such thing as pure objectivity in in physics, that even here the result of the experiment, nature's answer, depends on the question put to it. In the answer there is always a bit of the question and a bit of the questioner himself; it reflects not only nature in itself, in its pure objectivity, but also gives back something of man, of what is characteristically ours, a bit of the human subject. This too, mutatis mutandis, is true of the question of God. There is no such thing as a mere observer. There is no such thing as pure objectivity. One can even say that the higher an object stands in human terms, the more it generates the center of individuality; and the more it engages the beholder's individuality, then the smaller the possibility of the mere distancing involved in pure objectivity. Thus, whenever an answer is presented as unemotionally objective, as a statement that finally goes beyond the prejudices of the pious and provides purely factual, scientific information, then it has to be said that the speaker has here fallen victim to self-deception. This kind of objectivity is quite simply denied to man. He cannot ask and exist as a mere observer. He who tries to be a mere observer experiences nothing. Even the reality "God" can only impinge on the vision of him who enters into the experiment with God--the experiment that we call faith. Only be entering does one experience; only by cooperating in the experiment does one ask at all; and only he who asks receives an answer. "

" It is the question that is also asked by modern political theory: Can politics accept truth as a structural category? Or must truth, as something unattainable, be relegated to the subjective sphere, its place taken by an attempt to build peace and justice using whatever instruments are available to power? By relying on truth, does not politics, in view of the impossibility of attaining consensus on truth, make itself a tool of particular traditions that in reality are merely forms of holding on to power?
And yet, on the other hand, what happens when truth counts for nothing? What kind of justice is then possible? Must there not be common criteria that guarantee real justice for all—criteria that are independent of the arbitrariness of changing opinions and powerful lobbies? Is it not true that the great dictatorships were fed by the power of the ideological lie and that only truth was capable of bringing freedom? "
