Catechesis: Ap XXIV THE MASS

Our opponents cannot produce a syllable from the Scriptures in support of the fairy tales which they teach so authoritatively in the church; nor do they have the support of the ancient church and the Fathers.... They [the Fathers] make it clear that they are talking about thanksgiving; hence they call it “eucharist.” We already said that a eucharistic sacrifice does not merit reconciliation but comes from the reconciled, just as afflictions do not merit reconciliation but are eucharistic sacrifices when the reconciled endure them.—Ap XXIV:65, 66, 67
