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 VIThe freedom or immunity from coercion in matters religious, which is the endowment of persons as individuals, is also to be recognized as their right when they act in community. Religious communities are a requirement of the social nature both of man and of religion itself.
