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.
Pope Paul VITrue humanism points the way toward God and acknowledges the task to which we are called, the task which offers us the real meaning of human life. Man is not the ultimate measure of man. Man becomes truly man only by passing beyond himself.
Pope Paul VINo member of the faithful could possibly deny that the Church is competent in her magisterium to interpret the natural moral law.
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 VI
