“The manner in which sacred doctrine is spread, this having been established, it becomes clear how much is expected from the Council in regard to doctrine. That is, the Twenty-first Ecumenical Council, which will draw upon the effective and important wealth of juridical, liturgical, apostolic, and administrative experiences, wishes to transmit the doctrine, pure and integral, without any attenuation or distortion, which throughout twenty centuries, notwithstanding difficulties and contrasts, has become the common patrimony of men. It is a patrimony not well received by all, but always a rich treasure available to men of good will.
Our duty is not only to guard this precious treasure, as if we were concerned only with antiquity, but to dedicate ourselves with an earnest will and without fear to that work which our era demands of us, pursuing thus the path which the Church has followed for twenty centuries.”
St. Pope John XXIII
