If humanity today succeeds in combining the new scientific capacities with a strong ethical dimension, it will certainly be able to promote the environment as a home and a resource for...all...and will be able to eliminate the causes of pollution and to guarantee adequate conditions of hygiene and health for small groups as well as for vast human settlements.

Each man, in his suffering, can also become a sharer in the redemptive suffering of Christ.

Technology that pollutes can also cleanse, production that amasses can also distribute justly, on condition that the ethic of respect for life and human dignity, for the rights of today's generations and those to come, prevails.

The greatest deception, and the deepest source of unhappiness, is the illusion of finding life by excluding God, of finding freedom by excluding moral truths and personal responsibility.

The obligation to earn one's bread by the sweat of one's brow also presumes the right to do so. A society in which this right is systematically denied, in which economic policies do not allow workers to reach satisfactory levels of employment, cannot be justified from an ethical point of view, nor can that society attain social peace.

Creating the human race in His own image and continually keeping it in being, God inscribed in the humanity of man and woman the vocation... of love and communion. Love is therefore the fundamental and innate vocation of every human being.

For by his incarnation the Son of God united himself in a certain way with every man. He labored with human hands... and loved with a human heart. Born of Mary the Virgin, he truly became one of us.
