Without repeating everything that we have already mentioned, it is appropriate first of all to emphasize the following point: for the Church, the first means of evangelization is the witness of an authentically Christian life, given over to God in a communion that nothing should destroy and at the same time given to one's neighbor with limitless zeal. As we said recently to a group of lay people, โModern man listens more willingly to witnesses than to teachers, and if he does listen to teachers, it is because they are witnesses.
Pope Paul VIPeace is not merely the absence of war. Nor can it be reduced solely to the maintenance of a balance of power between enemies. Nor is it brought about by dictatorship. Instead, it is rightly and appropriately called "an enterprise of justice" (Is. 32:7). Peace results from that order structured into human society by its divine founder, and actualized by men as they thirst after ever greater justice.
Pope Paul VIWe see in these swift and skillful travelers a symbol of our life, which seeks to be a pilgrimage and a passage on this earth for the way of heaven.
Pope Paul VIIf 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."
