The command to the Twelve to go out and proclaim the Good News is also valid for all Christians, though in a different way.... the Good News of the kingdom which is coming and which has begun is meant for all people of all times. Those who have received the Good News and who have been gathered by it into the community of salvation can and must communicate and spread it.
Pope Paul VIWe see in these swift and skillful travelers a symbol of our life, which seeks to be a pilgrimage and a passage on this earth for the way of heaven.
Pope Paul VIThe 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
