In the Old Law the people brought to the temple whatever they wished the priests to offer up for them--sometimes a lamb, sometimes a dove, sometimes fruit, etc. The offering or sacrifice was theirs, and they offered it up by the hands of the priests. In the early ages of the Church the Christians brought to the priests the bread and wine to be consecrated and offered up at Mass. Now as the bread and wine used at the Mass must be of a particular kind, namely, wheaten bread and wine of the grape, there was some danger of the people not bringing the proper kind: so instead of the people bringing these things themselves, the priests began to buy them, and the people gave him money for his own support; and thus you have the origin of offering money to the priest for celebrating Mass for your intention. The money is not to pay for the Mass, because you could not buy any sacred thing without committing sin. The priest may use the money also for the candles burned, the vestments and sacred vessels, etc., used at the Mass. To buy a holy thing for money is the sin of simony--so called after Simon, a magician, who tried to bribe the Apostles to give him Confirmation when he was unworthy of it. To buy religious articles before they are blessed is not simony, nor even after they are blessed, if you pay only for the material of which they are made; but if you tried to buy the blessing, it would be simony. When the Holy Mass is offered, the fruits or benefits of it are divided into four classes. The first benefit comes to the priest who celebrates the Mass; the second, to the one for whom he offers the Mass; the third benefit to those who are present at it; and the fourth to all the faithful throughout the world. *270 Q. Which is the best manner of hearing Mass? A. The best manner of hearing Mass is to offer it to God with the priest for the same purpose for which it is said, to meditate on Christ's sufferings and death, and to go to Holy Communion. That is, to offer it up for whatever intention the priest is offering it--for the dead, for the conversion of sinners, for the good of others, etc.; but especially for the four ends of which I have already spoken--to worship God, thank Him, etc. "Christ's death," of which it reminds us. "Holy Communion," if we are in a state of grace, and have prepared to receive Communion.
