The only reason to possibly use screens is to be able to display beautiful pieces of sacred art in a particular space.

Screens can be used tastefully.

Well....some of the organs depend on electricity.

... hymnals or printed worship aids ... buried in it, not looking at Father, the artwork or the altar or whatever. Their head will be down, reducing the chance of any sound they make being heard.

"The era of candles is over we need to transition to incandescent bulbs."

7. But while We derive no little satisfaction from the wholesome results of the movement just described, duty obliges Us to give serious attention to this "revival" as it is advocated in some quarters, and to take proper steps to preserve it at the outset from excess or outright perversion.

8. Indeed, though we are sorely grieved to note, on the one hand, that there are places where the spirit, understanding or practice of the sacred liturgy is defective, or all but inexistent, We observe with considerable anxiety and some misgiving, that elsewhere certain enthusiasts, over-eager in their search for novelty, are straying beyond the path of sound doctrine and prudence. Not seldom, in fact, they interlard their plans and hopes for a revival of the sacred liturgy with principles which compromise this holiest of causes in theory or practice, and sometimes even taint it with errors touching Catholic faith and ascetical doctrine.

9. Yet the integrity of faith and morals ought to be the special criterion of this sacred science, which must conform exactly to what the Church out of the abundance of her wisdom teaches and prescribes. It is, consequently, Our prerogative to commend and approve whatever is done properly, and to check or censure any aberration from the path of truth and rectitude.

The worship rendered by the Church to God must be, in its entirety, interior as well as exterior. It is exterior because the nature of man as a composite of body and soul requires it to be so. Likewise, because divine Providence has disposed that "while we recognize God visibly, we may be drawn by Him to love of things unseen."[26] Every impulse of the human heart, besides, expresses itself naturally through the senses; and the worship of God, being the concern not merely of individuals but of the whole community of mankind, must therefore be social as well. This obviously it cannot be unless religious activity is also organized and manifested outwardly. Exterior worship, finally, reveals and emphasizes the unity of the mystical Body, feeds new fuel to its holy zeal, fortifies its energy, intensifies its action day by day: "for although the ceremonies themselves can claim no perfection or sanctity in their won right, they are, nevertheless, the outward acts of religion, designed to rouse the heart, like signals of a sort, to veneration of the sacred realities, and to raise the mind to meditation on the supernatural. They serve to foster piety, to kindle the flame of charity, to increase our faith and deepen our devotion. They provide instruction for simple folk, decoration for divine worship, continuity of religious practice. They make it possible to tell genuine Christians from their false or heretical counterparts."[27]

24. But the chief element of divine worship must be interior. For we must always live in Christ and give ourselves to Him completely, so that in Him, with Him and through Him the heavenly Father may be duly glorified. The sacred liturgy requires, however, that both of these elements be intimately linked with each another. This recommendation the liturgy itself is careful to repeat, as often as it prescribes an exterior act of worship. Thus we are urged, when there is question of fasting, for example, "to give interior effect to our outward observance."[28] Otherwise religion clearly amounts to mere formalism, without meaning and without content. You recall, Venerable Brethren, how the divine Master expels from the sacred temple, as unworthily to worship there, people who pretend to honor God with nothing but neat and wellturned phrases, like actors in a theater, and think themselves perfectly capable of working out their eternal salvation without plucking their inveterate vices from their hearts.[29] It is, therefore, the keen desire of the Church that all of the faithful kneel at the feet of the Redeemer to tell Him how much they venerate and love Him. She wants them present in crowds - like the children whose joyous cries accompanied His entry into Jerusalem - to sing their hymns and chant their song of praise and thanksgiving to Him who is King of Kings and Source of every blessing. She would have them move their lips in prayer, sometimes in petition, sometimes in joy and gratitude, and in this way experience His merciful aid and power like the apostles at the lakeside of Tiberias, or abandon themselves totally, like Peter on Mount Tabor, to mystic union with the eternal God in contemplation.

25. It is an error, consequently, and a mistake to think of the sacred liturgy as merely the outward or visible part of divine worship or as an ornamental ceremonial. No less erroneous is the notion that it consists solely in a list of laws and prescriptions according to which the ecclesiastical hierarchy orders the sacred rites to be performed.

26. It should be clear to all, then, that God cannot be honored worthily unless the mind and heart turn to Him in quest of the perfect life, and that the worship rendered to God by the Church in union with her divine Head is the most efficacious means of achieving sanctity.

27. This efficacy, where there is question of the eucharistic sacrifice and the sacraments, derives first of all and principally from the act itself (ex opere operato). But if one considers the part which the Immaculate Spouse of Jesus Christ takes in the action, embellishing the sacrifice and sacraments with prayer and sacred ceremonies, or if one refers to the "sacramentals" and the other rites instituted by the hierarchy of the Church, then its effectiveness is due rather to the action of the church (ex opere operantis Ecclesiae), inasmuch as she is holy and acts always in closest union with her Head.

28. In this connection, Venerable Brethren, We desire to direct your attention to certain recent theories touching a so-called "objective" piety. While these theories attempt, it is true, to throw light on the mystery of the Mystical Body, on the effective reality of sanctifying grace, on the action of God in the sacraments and in the Mass, it is nonetheless apparent that they tend to belittle, or pass over in silence, what they call "subjective," or "personal" piety.

29. It is an unquestionable fact that the work of our redemption is continued, and that its fruits are imparted to us, during the celebration of the liturgy, notable in the august sacrifice of the altar. Christ acts each day to save us, in the sacraments and in His holy sacrifice. By means of them He is constantly atoning for the sins of mankind, constantly consecrating it to God. Sacraments and sacrifice do, then, possess that "objective" power to make us really and personally sharers in the divine life of Jesus Christ. Not from any ability of our own, but by the power of God, are they endowed with the capacity to unite the piety of members with that of the head, and to make this, in a sense, the action of the whole community. From these profund considerations some are led to conclude that all Christian piety must be centered in the mystery of the Mystical Body of Christ, with no regard for what is "personal" or "subjective, as they would have it. As a result they feel that all other religious exercises not directly connected with the sacred liturgy, and performed outside public worship should be omitted.

30. But though the principles set forth above are excellent, it must be plain to everyone that the conclusions drawn from them respecting two sorts of piety are false, insidious and quite pernicious.

On the contrary, they can adopt some other method which proves easier for certain people; for instance, they can lovingly meditate on the mysteries of Jesus Christ or perform other exercises of piety or recite prayers which, though they differ from the sacred rites, are still essentially in harmony with them.

Not seldom, in fact, they interlard their plans and hopes for a revival of the sacred liturgy with principles which compromise this holiest of causes in theory or practice, and sometimes even taint it with errors touching Catholic faith and ascetical doctrine.
