19 Let us now turn our thoughts from human society to the immediate affairs of the Church, for it is necessary that Our soul, stricken with the evils of the times, should seek consolation in one direction at least. Over and above those luminous proofs of the divine power and indefectibility enjoyed by the Church, We find a source of no small consolation in the remarkable fruits of the active foresight of our Predecessor, Pope Pius X, who shed upon the Apostolic Chair the lustre of a most holy life. For We see as a result of his efforts a revival of religious spirit in the clergy throughout the whole world; the piety of the Christian people revived; activity and discipline stimulated in Catholic associations; the foundation and increase of episcopal sees; provision made for the education of ecclesiastical students in harmony with the canonical requirements and in so far as necessary with the needs of the times; the saving of the teaching of sacred science from the dangers of rash innovations; musical art brought to minister worthily to the dignity of sacred functions; the Faith spread far and wide by new missions of heralds of the Gospel.
