Here there is need that a man practise 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. III. The sermon ought to be nothing else than the proclamation of this testament. But who can hear it if no one preaches it? Now, they who ought to preach it, themselves do not know it. This is why the sermons ramble off into other unprofitable stories, and thus Christ is forgotten, while we fare like the man in II. Kings vii: we see our riches but do not enjoy them. Of which the Preacher also says, "This is a great evil, when God giveth a man riches, and giveth him not power to enjoy them." So we look on at unnumbered masses and do not know whether the mass be a testament, or what it be, just as if it were any other common good work by itself. O God, how exceeding blind we are! But where this is rightly preached, it is necessary that it be diligently heard, grasped, retained, often thought of, and that the faith be thus strengthened against all the temptation of sin, whether past, or present, or to come.
