Whatever were our opinions about the Council's various doctrines before its conclusions were promulgated, today our adherence to the decisions of the Council must be whole hearted and without reserve; it must be willing and prepared to give them the service of our thought, action and conduct. The Council was something very new: not all were prepared to understand and accept it. But now the conciliar doctrine must be seen as belonging to the magisterium of the Church and, indeed, be attributed to the breath of the Holy Spirit.
--Pope Paul VI to the Roman Curia, 23 April, 1966
