"No one can fail," wrote the pope, "to be stirred by those numerous passages of the Psalms which proclaim so loudly the immense majesty of God, His omnipotence, His unutterable justice, His goodness and clemency . . . . Who can fail to be inspired . . . by those thanksgivings for God's benefits, by those lowly and trustful prayers for benefits desired, by those cries of the penitent soul deploring its sins? Who is not kindled with love for the picture of Christ the Redeemer so lovingly shadowed forth, whose voice Augustine heard in all the Psalms, praising or mourning, rejoicing in hope or longing for accomplishment? With good reason was provision made in past ages by decrees of the Roman pontiffs, canons of councils, and monastic laws that both sections of the clergy should chant or recite the whole Psalter every week." The pope spoke of the many pleas that had reached him that the old custom might be restored, and of the work that had been done to this effect, which was but a prelude to a further emendation of the Breviary and the Missal.
The reform of the Roman Curia was another undertaking, which did much to simplify the government of the Church. The various Roman Congregations were founded by Sixtus V to study questions submitted to the decision of the pope and to deal with any legal questions that might arise; and as persons of experience and mature judgement alone should deal with these matters, various committees were formed, each of which attended to its own particular branch of business. But the organization of the different congregations needed to be adapted to the requirements of the present day. Pius X, with the practical spirit which distinguished all his undertakings, completely remodelled the curia, fixing the number of congregations at thirteen, and defining clearly the work of each. The constitution "Sapienti consilio" on this matter instituted also many other important reforms in the tribunals and offices of the curia.
The purchase of the Palazzo Mariscotti, assigned to the Cardinal Vicar of Rome, enabled Pius X to carry out another long-cherished plan, for the thorough reform of his own diocese, inadequate in its organization to the needs of the present day. Want of space, which had been the chief difficulty in the way of reorganization, having been thus supplied for, the necessary reforms were at once set on foot. In many other important matters the needs of modern times called for the simplification and amendment of methods that had become obsolete. The reform and codification of canon law was another laborious work carried on by the pope for eleven years, and brought to a conclusion under his successor Benedict XV.
