If the world is made to furnish each individual with the means of livelihood and the instruments for his growth and progress, each man has therefore the right to find in the world what is necessary for himself. The recent Council reminded us of this: "God intended the earth and all that it contains for the use of every human being and people. Thus, as all men follow justice and unite in charity, created goods should abound for them on a reasonable basis."

To wage war on misery and to struggle against injustice is to promote, along with improved conditions, the human and spiritual progress of all men, and therefore the common good of humanity. Peace cannot be limited to a mere absence of war, the result of an ever precarious balance of forces. No, peace is something that is built up day after day, in the pursuit of an order intended by God, which implies a more perfect form of justice among men.

Christ did not found an abstract religion, a mere school of religious thought. He setup a community of apostles, of teachers, with the task of spreading His message and so giving rise to a society of believers: His Church. He promised the Spirit of truth to His Church and then sent Him.

It is called the real presence, not in an exclusive sense, as though other forms of presence were not real, but by reason of its excellence. It is the substantial presence by which Christ is made present without doubt, whole and entire, God and man.

No member of the faithful could possibly deny that the Church is competent in her magisterium to interpret the natural moral law.

Of all human activities, man's listening to God is the supreme act of his reasoning and will.

Physics does not change the nature of the world it studies, and no science of behavior can change the essential nature of man, even though both sciences yield technologies with a vast power to manipulate the subject matters.
