Q. 1. What is the Humeral Veil used for?
A. 1. The Humeral Veil is worn so as to cover the back and shoulders (where it gets its name) and its two ends hang down in front. To prevent its falling from the shoulders, it is fastened across the chest with clasps or ribbons attached to the border. The Humeral Veil is worn by the priest or deacon in processions of the Blessed Sacrament, in giving Benediction, in carrying the Host to its repository on Holy Thursday, and bringing it back to the altar on Good Friday.
In processions of the Blessed Sacrament and at Benediction given with the Monstrance, only the hands are placed under the humeral veil; in other cases, it covers the sacred vessel which contains the Host. The Humeral Veil is usually and properly some shade of white (from ivory to white is acceptable).
