Art at the service of the liturgy
41. The profound connection between beauty and the liturgy should make us attentive to every work of art placed at the service of the celebration. (122) Certainly an important element of sacred art is church architecture, (123) which should highlight the unity of the furnishings of the sanctuary, such as the altar, the crucifix, the tabernacle, the ambo and the celebrant's chair. Here it is important to remember that the purpose of sacred architecture is to offer the Church a fitting space for the celebration of the mysteries of faith, especially the Eucharist. (124) The very nature of a Christian church is defined by the liturgy, which is an assembly of the faithful (ecclesia) who are the living stones of the Church (cf. 1 Pet 2:5).
This same principle holds true for sacred art in general, especially painting and sculpture, where religious iconography should be directed to sacramental mystagogy. A solid knowledge of the history of sacred art can be advantageous for those responsible for commissioning artists and architects to create works of art for the liturgy. Consequently it is essential that the education of seminarians and priests include the study of art history, with special reference to sacred buildings and the corresponding liturgical norms. Everything related to the Eucharist should be marked by beauty. Special respect and care must also be given to the vestments, the furnishings and the sacred vessels, so that by their harmonious and orderly arrangement they will foster awe for the mystery of God, manifest the unity of the faith and strengthen devotion (125).
