What color must the altar cloth be? I noticed one parish with green and heard that another parish was considering changing the color with the liturgical seasons? Is there any binding document concerning this?
According to the General Instruction of the Roman Missal, n.268, "At least one cloth should be placed on the altar out of reverence for the celebration of the memorial of the Lord and the banquet that gives us his body and blood. The shape, size, and decoration of the altar cloth should be in keeping with the design of the altar."
While the color is not mentioned, the traditional color has been white as a sign of the faithful's purity and devotion "For the fine linen are the justifications of saints" (Apoc., xix,
8), as a memory of the shroud, and as a sign God's faithful who surround Christ. White is also the easiest color to clean.
