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.
Pope Paul VIThere are those who ask what authority, what theological qualification, the Council intended to give to its teachings, knowing that it avoided issuing solemn dogmatic definitions backed by the Church's infallible teaching authority. The answer is known by those who remember the conciliar declaration of March 6, 1964, repeated on November 16, 1964. In view of the pastoral nature of the Council, it avoided proclaiming in an extraordinary manner any dogmata carrying the mark of infallibility.
Pope Paul VIJustice is not always an open and shut case - sometimes we have to work for it. If you want peace, you must work for justice.
Pope Paul VIFor 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.

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.
