22. Traces of this usage have survived in three customs. The first, that the first and last prayer of the mass are called "collects," that is, "collections"; which indicates that these prayers were spoken as a blessing and thanksgiving over the food which had been collected, to bless it and give thanks to God, according to the teaching of St. Paul [1 Cor. 10:30, 31]. The second, when the people after the Gospel proceed to the offering; from which the chant which is sung at that time is called "Offertory," that is, an offering. The third, that the priest elevates in the paten and offers to God the still unblessed host, at the same time that the offertory is being sung and the people are making their offering; by which is shown that the sacrament is not offered to God by us, but only these "collects" and offerings of food and gifts that have been gathered, in order that God may be thanked for them, and they may be blessed, to be distributed to the needy. For afterward, when the priest, in the "low mass," [15] elevates the blessed host and cup, there is not a word said about the sacrifice, where he should most of all make mention of the sacrifice, if the mass were a sacrifice: but, as I have said above,[16] he elevates it not toward God, but toward us, to remind us of the testament, and to incite us to faith in the same. In like manner, when he receives or administers the sacrament, he does not mention the sacrifice by a single word; which must and should be done were the sacrament a sacrifice. Therefore, the mass dare not and cannot be called or be a sacrifice because of the sacrament, but only because of the food which is gathered and the prayer with which God is thanked and with which it is blessed. [Sidenote: The Offering at the Mass] 23. Now the custom of gathering food and money at the mass has fallen into disuse, and not more than a trace of it remains in the offering of the pfennig on the high festivals, and especially on Easter Day, when they still bring cakes, meat, eggs, etc., to church to be blessed. Now in place of such offerings and collections, endowed churches, monastic houses and hospitals have been erected, and should be maintained for the sole purpose that the needy in every city may be given all they need, that there be no beggar or needy one among the Christians, but that each and all may have from the mass enough for body and soul.
