Catechesis: The Mass

The Mass is to be used for the purpose of offering the sacrament to those who need consolation, just as ambrose says: “Because I always sin, I ought always to take the medicine.” Since the Mass is such an imparting of the sacrament, among us one common Mass is held on every holy day, and it is also administered on other days if there are those who desire it.—AC XXIV:33,34 (Latin)
