The task of evangelizing all people constitutes the essential mission of the Church. It is a task and mission which the vast and profound changes of present-day society make all the more urgent. Evangelizing is in fact the grace and vocation proper to the Church, her deepest identity. She exists in order to evangelize.
Pope Paul VIPerhaps the Lord has called me and preserved me for this service not because I am particularly fit for it, or so that I can govern and rescue the Church from her present difficulties, but so that I can suffer something for the Church, and in that way it will be clear that he, and no other, is her guide and saviour
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.
