The preaching of the faith has lost nothing of its relevance in our times. The Church has a sacred duty to proclaim it without any whittling-down, just as Christ revealed it, and no consideration of time or circumstance can lessen the strictness of this obligation.
Pope Pius XIIThe key to seeing why there should be a Eucharistic worship distinct from the Mass is that the Eucharist is Jesus Christ. No less than His contemporaries in Palestine adored and implored Him for the favors they needed, so we should praise, thank Him, and implore Him for what we need.
Pope Pius XIIJust as the divine Redeemer, dying on the Cross, offered Himself as Head of the whole human race to the eternal Father, so also in this "clean oblation" (Mal 1:2), He, as Head of the Church, offers not only Himself but, in Himself, all His mystical members.
