Since ceremonies, however, ought to be observed both to teach men Scripture, and that those admonished by the Word may conceive faith and fear [of God, and obtain comfort] and thus also may pray (for these are the designs of ceremonies ), we retain the Latin language on account of those who are learning and understand Latin, and we mingle with it German hymns, in order that the people also may have something to learn, and by which faith and fear may be called forth. This custom has always existed in the churches. For although some more frequently, and others more rarely, introduced German hymns, nevertheless the people almost everywhere sang something in their own tongue. [Therefore, this is not such a new departure.] It has, however, nowhere been written or represented that the act of hearing lessons not understood profits men, or that ceremonies profit, not because they teach or admonish, but _ex opere operato_, because they are thus performed or are looked upon. Away with such pharisaic opinions! [Ye sophists ought to be heartily ashamed of such dreams!] The fact that we hold only Public or Common Mass [at which the people also commune, not Private Mass] is no offense against the Church catholic. For in the Greek churches even to-day private Masses are not held, but there is only a public Mass, and that on the Lord's Day and festivals. In the monasteries daily Mass is held, but this is only public. These are the traces of former customs. For nowhere do the ancient writers before Gregory make mention of private Masses. We now omit noticing the nature of their origin. It is evident that after the mendicant monks began to prevail, from most false opinions and on account of gain they were so increased that all good men for a long time desired some limit to this thing. Although St. Francis wished to provide aright for this matter, as he decided that each fraternity should be content with a single common Mass daily, afterwards this was changed, either by superstition or for the sake of gain. Thus, where it is of advantage, they themselves change the institutions of the Fathers; and afterwards they cite against us the authority of the Fathers. Epiphanius writes that in Asia the Communion was celebrated three times a week, and that there were no daily Masses. And indeed he says that this custom was handed down from the apostles. For he speaks thus: Assemblies for Communion were appointed by the apostles to be held on the fourth day, on Sabbath eve, and the Lord's Day.
