The nature and beauty of the sancturary and all its furnishings should foster devotion and express visurally the holiness of the mysteries celebrated. The ornamentation of a church should contribute toward its noble simplicity rather than to ostentation. In the choice of elements, attention should be paid to authenticity and the intention of fostering the instruction of the faithful and the dignity of the entire sacred place. Moderation should be observed in the decoration of the altar. (Ch 5 General Instruction fo the Roman Missal)
