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'.

Peace 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. Instead, it is rightly and appropriately called "an enterprise of justice" (Is. 32:7). Peace results from that order structured into human society by its divine founder, and actualized by men as they thirst after ever greater justice.
