You also realize, Venerable Brothers, that the Eucharist is reserved in churches or oratories to serve as the spiritual center of a religious community or a parish community, indeed of the whole Church and the whole of mankind, since it contains, beneath the veil of the species, Christ the invisible Head of the Church, the Redeemer of the world, the center of all hearts, 'by whom all things are and by whom we exist'.
Pope Paul VIThe unique and indivisible existence of the Lord glorious in heaven, is not multiplied, but is rendered present by the sacrament in the many places on earth where Mass is celebrated. And this existence remains present, after the sacrifice, in the Blessed Sacrament, which is, in the tabernacle, the living heart of each of our churches.

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.

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.
