Episcopal gloves or Pontifical gloves (chirothecœ, called also at an earlier date manicœ, wanti) : a Roman Catholic pontifical vestment worn a by bishop when celebrating Solemn Pontifical Mass. They are worn from the beginning of the Mass until the offertory, when they are removed. They can be elaborately embroidered and generally match the liturgical color of the Mass. They are not worn for Good Friday or Requiem Masses. While normally reserved for bishops, other prelates entitled to use pontificals, including abbots, may also use them without a special papal privilege. The gloves are considered symbolic of purity, the performance of good works and carefulness in procedure.
