VESTMENTS: 

(GIRM 335) In the Church, which is the Body of Christ, not all members have the same function. This diversity of offices is shown outwardly in the celebration of the Eucharist by the diversity of sacred vestments, which must therefore be a sign of the function proper to each minister. Moreover, these same sacred vestments should also contribute to the decoration of the sacred action itself. The vestments worn by Priests and Deacons, as well as the attire worn by lay ministers, are blessed before being put into liturgical use according to the rite described in the Roman Ritual.
