I. We have now seen how many good works there are in the Second Commandment, which however are not good in themselves, unless they are done in faith and in the assurance of divine favor; and how much we must do, if we take heed to this Commandment alone, and how we, alas! busy ourselves much with other works, which have no agreement at all with it. Now follows the Third Commandment: “Thou shalt hallow the day of rest.” In the First Commandment is prescribed our heart’s attitude toward God in thoughts, in the Second, that of our mouth in words, in this Third is prescribed our attitude toward God in works; and it is the first and right table of Moses, on which these three Commandments are written, and they govern man on the right side, namely, in the things which concern God, and in which God has to do with man and man with God, without the mediation of any creature.
The first works of this Commandment are plain and outward, which we commonly call worship, such as going to mass, praying, and hearing a sermon on holy days. So understood there are very few works in this Commandment; and these, if they are not done in assurance of and with faith in God’s favor, are nothing, as was said above. Hence it would also be a good thing if there were fewer saint’s days, since in our times the works done on them are for the greater part worse than those of the work days, what with loafing, gluttony, and drunkenness, gambling and other evil deeds; and then, the mass and the sermon are listened to without edification, the prayer is spoken without faith. It almost happens that men think it is sufficient that we look on at the mass with our eyes, hear the preaching with our ears, and say the prayers with our mouths. It is all so formal and superficial! We do not think that we might receive something out of the mass into our hearts, learn and remember something out of the preaching, seek, desire and expect something in our prayer. Although in this matter the bishops and priests, or they to whom the work of preaching is entrusted, are most at fault, because they do not preach the Gospel, and do not teach the people how they ought to look on at mass, hear preaching and pray. Therefore, we will briefly explain these three works.
II. In the mass it is necessary that we attend with our a hearts also; and we do attend, when we exercise faith in our hearts. Here we must repeat the words of Christ, when He institutes the mass and says, “Take and eat, this is My Body, which is given for you”; in like manner over the cup, “Take and drink ye all of it: this is a new, everlasting Testament in My Blood, which is shed for you and for many for the remission of sins. This shall ye do, as oft as ye do it, in remembrance of Me.” In these words Christ has made for Himself a memorial or anniversary, to be daily observed in all Christendom, and has added to it a glorious, rich, great testament, in which no interest, money or temporal possessions are bequeathed and distributed, but the forgiveness of all sins, grace and mercy unto eternal life, that all who come to this memorial shall have the same testament; and then He died, whereby this testament has become permanent and irrevocable. In proof and evidence of which, instead of letter and seal, He has left with us His own Body and Blood under the bread and wine.
Here there is need that a man practice the first works of this Commandment right well, that he doubt not that what Christ has said is true, and consider the testament sure, so that he make not Christ a liar. For if you are present at mass and do not consider nor believe that here Christ through His testament has bequeathed and given you forgiveness of all your sins, what else is it, than as if you said: “I do not know or do not believe that it is true that forgiveness of my sins is here bequeathed and given me”? Oh, how many masses there are in the world at present! but how few who hear them with such faith and benefit! Most grievously is God provoked to anger thereby. For this reason also no one shall or can reap any benefit from the mass except he be in trouble of soul and long for divine mercy, and desire to be rid of his sins; or, if he have an evil intention, he must be changed during the mass, and come to have a desire for this testament. For this reason in olden times no open sinner was allowed to be present at the mass.
When this faith is rightly present, the heart must be made joyful by the testament, and grow warm and melt in God’s love. Then will follow praise and thanksgiving with a pure heart, from which the mass is called in Greek Eucharistia, that is, “thanksgiving,” because we praise and thank God for this comforting, rich, blessed testament, just as he gives thanks, praises and is joyful, to whom a good friend has presented a thousand and more gulden. Although Christ often fares like those who make several persons rich by their testament, and these persons never think of them, nor praise or thank them. So our masses at present are merely celebrated, without our knowing why or wherefore, and consequently we neither give thanks nor love nor praise, remain parched and hard, and have enough with our little prayer. Of this more another time.
