“Knowing is not simply a material act, since the object that is known always conceals something beyond the empirical datum. All our knowledge, even the most simple, is always a minor miracle, since it can never be fully explained by the material instruments that we apply to it. In every truth there is something more than we would have expected, in the love that we receive there is always an element that surprises us.”

“There are times when the burden of need and our own limitations might tempt us to become discouraged. But precisely then we are helped by the knowledge that, in the end, we are only instruments in the Lord's hands; and this knowledge frees us from the presumption of thinking that we alone are personally responsible for building a better world. In all humility we will do what we can, and in all humility we will entrust the rest to the Lord. It is God who governs the world, not we. We offer him our service only to the extent that we can, and for as long as he grants us the strength. To do all we can with what strength we have, however, is the task which keeps the good servant of Jesus Christ always at work: “The love of Christ urges us on” (2 Cor 5:14).”

“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.”

“Since man always remains free and since his freedom is always fragile, the kingdom of good will never be definitively established in this world. Anyone who promises the better world that is guaranteed to last forever is making a false promise; he is overlooking human freedom. Freedom must be constantly won over for the cause of good. Free assent to the good never exists simply by itself. If there were structures which could irrevocably guarantee a determined and good state of the world, man's freedom would be denied, and hence they would not be good structures at all.”

“...when today as believers in our age we hear it said, a little enviously perhaps, that in the Middle Ages everyone without exception in our lands was a believer, it is a good thing to cast a glance behind the scenes, as we can today, thanks to historical research. This will tell us that even in those days there was the great mass of nominal believers and a relatively small number of people who had really entered into the inner movement of belief. It will show us that for many belief was only a ready-made mode of life, by which for them the exciting adventure really signified by the word credo was at least as much concealed as disclosed. This is simply because there is an infinite gulf between God and man; because man is fashioned in such a way that his eyes are only capable of seeing what is not God, and thus for man God is and always will be the essentially invisible, something lying outside his field of vision. ...”

“Are we not perhaps all afraid in some way? If we let Christ enter fully into our lives, if we open ourselves totally to him, are we not afraid that He might take something away from us? Are we not perhaps afraid to give up something significant, something unique, something that makes life so beautiful? Do we not then risk ending up diminished and deprived of our freedom? . . . No! If we let Christ into our lives, we lose nothing, nothing, absolutely nothing of what makes life free, beautiful and great. No! Only in this friendship are the doors of life opened wide. Only in this friendship is the great potential of human existence truly revealed. Only in this friendship do we experience beauty and liberation. And so, today, with great strength and great conviction, on the basis of long personal experience of life, I say to you, dear young people: Do not be afraid of Christ! He takes nothing away, and he gives you everything. When we give ourselves to him, we receive a hundredfold in return. Yes, open, open wide the doors to Christ – and you will find true life. Amen.”

“We are sinners. But we should not take the failure to live up to this high moral standard as an authoritative objection to the truth. We should try to do as much good as we can and to support and put up with each other. .”
