For you deal here above all with human life, and human life is sacred; no one may dare make an attempt upon it. Respect for life, even with regard to the great problem of the birth rate, must find here in your Assembly its highest affirmation and its most rational defense. Your task is to ensure that there is enough bread on the tables of mankind, and not to encourage an artificial control of births, which would be irrational, in order to diminish the number of guests at the banquet of life.
Pope Paul VITwo conditions render difficult this historic situation of mankind: It is full of tremendously deadly armament, and it has not progressed morally as much as it has scientifically and technically.
Pope Paul VIIndividual initiative alone and the mere free play of competition could never assure successful development. One must avoid the risk of increasing still more the wealth of the rich and the dominion of the strong, whilst leaving the poor in their misery and adding to the servitude of the oppressed.
Pope Paul VIFor peace is not simply the absence of warfare, based on a precarious balance of power; it is fashioned by efforts directed day after day toward the establishment of the ordered universe willed by God, with a more perfect form of justice among men.
Pope Paul VI
