This is all easily understood, if one only considers what the mass really is, namely, a testament and sacrament; that is, God's Word and promise, together with a sacred sign, the bread and the wine, under which Christ's body and blood are truly present. For by what process of reasoning could a man be said to do a good work for another when, like the others, he comes as one in need, and takes to himself the words and sign of God in which God promises and grants him grace and help? Surely, to receive God's Word, sign, and grace is not the imparting of good, or the doing of a good work, but is simply a "taking to oneself." [Sidenote: Abuses of the Mass: 3. The Mass as a Sacrifice] 21. Now, since the whole world has made a sacrifice of the mass, wherein they bring an offering to God, which without doubt is the third and very worst abuse, we must dearly distinguish between what we offer and what we do not offer in the mass. Beyond all doubt the word "offering" in the mass has arisen and has remained until now, because in the times of the Apostles, when some of the practices of the Old Testament were still observed, the Christians brought food, money and necessities, which were distributed in connection with mass among the needy, as I have said before.[13] For so we still read in Acts iv, that the Christians sold all that they had, and brought it to the feet of the Apostles, who then had it distributed and gave of the common possessions to every one as he needed. [Acts 4:34, 35] Even so the Apostle Paul teaches, that all food and whatsoever we use shall be blessed with prayer and the Word of God, and thanks be given to God therefor [Rom. 14:6, 7; 1 Cor. 10:30,31]; hence we say the Benedicite and Gratias[14] at table. Thus it was the custom of the Old Testament, when men thanked God for gifts received, that they lifted them up in their hands to God; as is written in the law of Moses. [Exod. 34:26; Num.15:19, 20] Therefore, the apostles also lifted up the offerings in this way, thanked God, and blessed, with the Word of God, food and whatever the Christians gathered. And Christ Himself, as St. Luke writes, lifted up the cup, gave thanks to God, drank of it, and gave to the others, before He instituted the sacrament and testament. [Luke 22:17] [Sidenote: The Collect and Offeratory]
