Certain elements of today's ecological crisis reveal its moral character. First among these is the indiscriminate application of advances in science and technology. Many recent discoveries have brought undeniable benefits to humanity. Indeed, they demonstrate the nobility of the human vocation to participate responsibly in God's creative action in the world. Unfortunately, it is now clear that the application of these discoveries in the fields of industry and agriculture have produced harmful long-term effects.

In this oasis of quiet, before the wonderful spectacle of nature, one easily experiences how profitable silence is, a good that today is ever more rare... In reality, only in silence does man succeed in hearing in the depth of his conscience the voice of God, which really makes him free. And vacations can help to rediscover and cultivate this indispensable interior dimension of human life.

We are now standing in the face of the greatest historical confrontation humanity has gone through. I do not think that wide circles of the American society or wide circles of the Christian community realize this fully. We are now facing the final confrontation between the Church and the anti-Church, of the Gospel versus the anti-Gospel.

Faced with the widespread destruction of the environment, people everywhere are coming to understand that we cannot continue to use the goods of the earth as we have in the past ... [A] new ecological awareness is beginning to emerge which rather than being downplayed, ought to be encouraged to develop into concrete programs and initiatives.

In suffocating the voice of conscience, passion carries with itself a restlessness of the body and the senses: it is the restlessness of the "external man." When the internal man has been reduced to silence, then passion, once it has been given freedom of action, so to speak, exhibits itself as an insistent tendency to satisfy the senses and the body.

I cannot fail to note once again that the poor constitute the modern challenge, especially for the well-off of our planet, where millions of people live in inhuman conditions and many are literally dying of hunger. It is not possible to announce God the Father to these brothers and sisters without taking on the responsibility of building a more just society in the name of Christ.

...if desire is predominant it can deform love between man and woman and rob them both of it.
