2501 Created "in the image of God,"294 man also expresses the truth of his relationship with God the Creator by the beauty of his artistic works. Indeed, art is a distinctively human form of expression; beyond the search for the necessities of life which is common to all living creatures, art is a freely given superabundance of the human being’s inner riches. Arising from talent given by the Creator and from man’s own effort, art is a form of practical wisdom, uniting knowledge and skill,295 to give form to the truth of reality in a language accessible to sight or hearing. To the extent that it is inspired by truth and love of beings, art bears a certain likeness to God’s activity in what he has created. Like any other human activity, art is not an absolute end in itself, but is ordered to and ennobled by the ultimate end of man.296
2502 Sacred art is true and beautiful when its form corresponds to its particular vocation: evoking and glorifying, in faith and adoration, the transcendent mystery of God - the surpassing invisible beauty of truth and love visible in Christ, who “reflects the glory of God and bears the very stamp of his nature,” in whom "the whole fullness of deity dwells bodily."297 This spiritual beauty of God is reflected in the most holy Virgin Mother of God, the angels, and saints. Genuine sacred art draws man to adoration, to prayer, and to the love of God, Creator and Savior, the Holy One and Sanctifier.
2503 For this reason bishops, personally or through delegates, should see to the promotion of sacred art, old and new, in all its forms and, with the same religious care, remove from the liturgy and from places of worship everything which is not in conformity with the truth of faith and the authentic beauty of sacred art.298
