184. Hence, he would do something very wrong and dangerous who would dare to take on himself to reform all these exercises of piety and reduce them completely to the methods and norms of liturgical rites. However, it is necessary that the spirit of the sacred liturgy and its directives should exercise such a salutary influence on them that nothing improper be introduced nor anything unworthy of the dignity of the house of God or detrimental to the sacred functions or opposed to solid piety.
185. Take care then, Venerable Brethren, that this true and solid piety increases daily and more under your guidance and bears more abundant fruit. Above all, do not cease to inculcate into the minds of all that progress in the Christian life does not consist in the multiplicity and variety of prayers and exercises of piety, but rather in their helpfulness towards spiritual progress of the faithful and constant growth of the Church universal. For the eternal Father "chose us in Him [Christ] before the foundation of the world that we should be holy and unspotted in His sight."[167] All our prayers, then, and all our religious practices should aim at directing our spiritual energies towards attaining this most noble and lofty end.
186. We earnestly exhort you, Venerable Brethren, that after errors and falsehoods have been removed, and anything that is contrary to truth or moderation has been condemned, you promote a deeper knowledge among the people of the sacred liturgy so that they more readily and easily follow the sacred rites and take part in them with true Christian dispositions.
187. First of all, you must strive that with due reverence and faith all obey the decrees of the Council of Trent, of the Roman Pontiffs, and the Sacred Congregation of Rites, and what the liturgical books ordain concerning external public worship.
188. Three characteristics of which Our predecessor Pius X spoke should adorn all liturgical services: sacredness, which abhors any profane influence; nobility, which true and genuine arts should serve and foster; and universality, which, while safeguarding local and legitimate custom, reveals the catholic unity of the Church.[168]
189. We desire to commend and urge the adornment of churches and altars. Let each one feel moved by the inspired word, "the zeal of thy house hath eaten me up";[169] and strive as much as in him lies that everything in the church, including vestments and liturgical furnishings, even though not rich nor lavish, be perfectly clean and appropriate, since all is consecrated to the Divine Majesty. If we have previously disapproved of the error of those who would wish to outlaw images from churches on the plea of reviving an ancient tradition, We now deem it Our duty to censure the inconsiderate zeal of those who propose for veneration in the Churches and on the altars, without any just reason, a multitude of sacred images and statues, and also those who display unauthorized relics, those who emphasize special and insignificant practices, neglecting essential and necessary things. They thus bring religion into derision and lessen the dignity of worship.
190. Let us recall, as well, the decree about "not introducing new forms of worship and devotion."[170] We commend the exact observance of this decree to your vigilance.
191. As regards music, let the clear and guiding norms of the Apostolic See be scrupulously observed. Gregorian chant, which the Roman Church considers her own as handed down from antiquity and kept under her close tutelage, is proposed to the faithful as belonging to them also. In certain parts of the liturgy the Church definitely prescribes it;[171] it makes the celebration of the sacred mysteries not only more dignified and solemn but helps very much to increase the faith and devotion of the congregation. For this reason, Our predecessors of immortal memory, Pius X and Pius XI, decree - and We are happy to confirm with Our authority the norms laid down by them - that in seminaries and religious institutes, Gregorian chant be diligently and zealously promoted, and moreover that the old Scholae Cantorum be restored, at least in the principal churches. This has already been done with happy results in not a few places.[172]
192. Besides, "so that the faithful take a more active part in divine worship, let Gregorian chant be restored to popular use in the parts proper to the people. Indeed it is very necessary that the faithful attend the sacred ceremonies not as if they were outsiders or mute onlookers, but let them fully appreciate the beauty of the liturgy and take part in the sacred ceremonies, alternating their voices with the priest and the choir, according to the prescribed norms. If, please God, this is done, it will not happen that the congregation hardly ever or only in a low murmur answer the prayers in Latin or in the vernacular."[173] A congregation that is devoutly present at the sacrifice, in which our Savior together with His children redeemed with His sacred blood sings the nuptial hymn of His immense love, cannot keep silent, for "song befits the lover"[174] and, as the ancient saying has it, "he who sings well prays twice." Thus the Church militant, faithful as well as clergy, joins in the hymns of the Church triumphant and with the choirs of angels, and, all together, sing a wondrous and eternal hymn of praise to the most Holy Trinity in keeping with words of the preface, "with whom our voices, too, thou wouldst bid to be admitted."[175]
193. It cannot be said that modern music and singing should be entirely excluded from Catholic worship. For, if they are not profane nor unbecoming to the sacredness of the place and function, and do not spring from a desire of achieving extraordinary and unusual effects, then our churches must admit them since they can contribute in no small way to the splendor of the sacred ceremonies, can lift the mind to higher things and foster true devotion of soul.
194. We also exhort you, Venerable Brethren, to promote with care congregational singing, and to see to its accurate execution with all due dignity, since it easily stirs up and arouses the faith and piety of large gatherings of the faithful. Let the full harmonious singing of our people rise to heaven like the bursting of a thunderous sea[176] and let them testify by the melody of their song to the unity of their hearts and minds[177], as becomes brothers and the children of the same Father.
195. What We have said about music, applies to the other fine arts, especially to architecture, sculpture and painting. Recent works of art which lend themselves to the materials of modern composition, should not be universally despised and rejected through prejudice. Modern art should be given free scope in the due and reverent service of the church and the sacred rites, provided that they preserve a correct balance between styles tending neither to extreme realism nor to excessive "symbolism," and that the needs of the Christian community are taken into consideration rather than the particular taste or talent of the individual artist. Thus modern art will be able to join its voice to that wonderful choir of praise to which have contributed, in honor of the Catholic faith, the greatest artists throughout the centuries. Nevertheless, in keeping with the duty of Our office, We cannot help deploring and condemning those works of art, recently introduced by some, which seem to be a distortion and perversion of true art and which at times openly shock Christian taste, modesty and devotion, and shamefully offend the true religious sense. These must be entirely excluded and banished from our churches, like "anything else that is not in keeping with the sanctity of the place."[178]
196. Keeping in mind, Venerable Brethren, pontifical norms and decrees, take great care to enlighten and direct the minds and hearts of the artists to whom is given the task today of restoring or rebuilding the many churches which have been ruined or completely destroyed by war. Let them be capable and willing to draw their inspiration from religion to express what is suitable and more in keeping with the requirements of worship. Thus the human arts will shine forth with a wondrous heavenly splendor, and contribute greatly to human civilization, to the salvation of souls and the glory of God. The fine arts are really in conformity with religion when "as noblest handmaids they are at the service of divine worship."[179]
197. But there is something else of even greater importance, Venerable Brethren, which We commend to your apostolic zeal, in a very special manner. Whatever pertains to the external worship has assuredly its importance; however, the most pressing duty of Christians is to live the liturgical life, and increase and cherish its supernatural spirit.
198. Readily provide the young clerical student with facilities to understand the sacred ceremonies, to appreciate their majesty and beauty and to learn the rubrics with care, just as you do when he is trained in ascetics, in dogma and in a canon law and pastoral theology. This should not be done merely for cultural reasons and to fit the student to perform religious rites in the future, correctly and with due dignity, but especially to lead him into closest union with Christ, the Priest, so that he may become a holy minister of sanctity.
199. Try in every way, with the means and helps that your prudence deems best, that the clergy and people become one in mind and heart, and that the Christian people take such an active part in the liturgy that it becomes a truly sacred action of due worship to the eternal Lord in which the priest, chiefly responsible for the souls of his parish, and the ordinary faithful are united together.
200. To attain this purpose, it will greatly help to select carefully good and upright young boys from all classes of citizens who will come generously and spontaneously to serve at the altar with careful zeal and exactness. Parents of higher social standing and culture should greatly esteem this office for their children. If these youths, under the watchful guidance of the priests, are properly trained and encouraged to fulfill the task committed to them punctually, reverently and constantly, then from their number will readily come fresh candidates for the priesthood. The clergy will not then complain - as, alas, sometimes happens even in Catholic places - that in the celebration of the august sacrifice they find no one to answer or serve them.
201. Above all, try with your constant zeal to have all the faithful attend the eucharistic sacrifice from which they may obtain abundant and salutary fruit; and carefully instruct them in all the legitimate ways we have described above so that they may devoutly participate in it. The Mass is the chief act of divine worship; it should also be the source and center of Christian piety. Never think that you have satisfied your apostolic zeal until you see your faithful approach in great numbers the celestial banquet which is a sacrament of devotion, a sign of unity and a bond of love.[180]
202. By means of suitable sermons and particularly by periodic conferences and lectures, by special study weeks and the like, teach the Christian people carefully about the treasures of piety contained in the sacred liturgy so that they may be able to profit more abundantly by these supernatural gifts. In this matter, those who are active in the ranks of Catholic Action will certainly be a help to you, since they are ever at the service of the hierarchy in the work of promoting the kingdom of Jesus Christ.
