About the Mass
"You have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the first-born who are enrolled in heaven, and to a judge who is God of all, and to the spirits of just men made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks more graciously than the blood of Abel." (Hebrews 12:22–24)
Commentaries on Eucharistic Chants
At Mass we use special liturgical books, such as the Roman Missal, Lectionary, Book of the Gospels, and Roman Gradual.
Various sacred vessels and linens are used at Mass, including the chalice, paten, cruets, lavabo dish, Communion patens, purificator, pall, and corporal.
For Mass, the priest wears sacred vestments: the amice, alb, cincture, stole, and chasuble.
