“Holy Mother Church has therefore always been the friend of the fine arts and has ever sought their noble help, with the special aim that all things set apart for use in divine worship should be truly worthy, becoming, and beautiful, signs and symbols of the supernatural world, and for this purpose she has trained artists. In fact, the Church has, with good reason, always reserved to herself the right to pass judgment upon the arts, deciding which of the works of artists are in accordance with faith, piety, and cherished traditional laws, and thereby fitted for sacred use.
The Church has been particularly careful to see that sacred furnishings should worthily and beautifully serve the dignity of worship, and has admitted changes in materials, style, or ornamentation prompted by the progress of the technical arts with the passage of time.”
-Sacrosanctum Concilium, 122
“Very rightly the fine arts are considered to rank among the noblest activities of man’s genius, and this applies especially to religious art and to its highest achievement, which is sacred art. These arts, by their very nature, are oriented toward the infinite beauty of God which they attempt in some way to portray by the work of human hands; they achieve their purpose of redounding to God’s praise and glory in proportion as they are directed the more exclusively to the single aim of turning men’s minds devoutly toward God.

The Church has further used her right of control over liturgical observance to protect the purity of divine worship against abuse from dangerous and imprudent innovations introduced by private individuals and particular churches. Thus it came about – during the 16th century, when usages and customs of this sort had become increasingly prevalent and exaggerated, and when private initiative in matters liturgical threatened to compromise the integrity of faith and devotion, to the great advantage of heretics and further spread of their errors – that in the year 1588, Our predecessor Sixtus V of immortal memory established the Sacred Congregation of Rites, charged with the defence of the legitimate rites of the Church and with the prohibition of any spurious innovation. This body fulfils even today the official function of supervision and legislation with regard to all matters touching the sacred liturgy.
58. It follows from this that the Sovereign Pontiff alone enjoys the right to recognize and establish any practice touching the worship of God, to introduce and approve new rites, as also to modify those he judges to require modification. Bishops, for their part, have the right and duty carefully to watch over the exact observance of the prescriptions of the sacred canons respecting divine worship. Private individuals, therefore, even though they be clerics, may not be left to decide for themselves in these holy and venerable matters, involving as they do the religious life of Christian society along with the exercise of the priesthood of Jesus Christ and worship of God; concerned as they are with the honour due to the Blessed Trinity, the Word Incarnate and His august mother and the other saints, and with the salvation of souls as well. For the same reason no private person has any authority to regulate external practices of this kind, which are intimately bound up with Church discipline and with the order, unity and concord of the Mystical Body and frequently even with the integrity of Catholic faith itself.
-Pope Pius XII
Mediator Dei, 58
The Pope said the Magisterium, the Church’s teaching authority, has the “duty to pay attention to what the Spirit tells the church through authentic manifestations of the ‘sense of the faithful’.”
But he told the theologians this sense “must not be confused with the sociological reality of majority opinion. That is something else. It is therefore important, and it is your task, to elaborate the criteria that permit discernment of authentic expressions of the ‘sense of the faithful.’”
“Bishops should dedicate themselves to their apostolic office as witness of Christ before all men. They should not only look after those who already follow the Prince of Pastors but should also wholeheartedly devote themselves to those who have strayed in any way from the path of truth or are ignorant of the Gospel of Christ and His saving mercy until finally all men walk “in all goodness and justice and truth””
-Christus Dominus, 11
