Link to Cantate Sermon 2 - Fourth Sunday after Easter
5. What will now become of all the priests, nuns and monks who, wishing to escape sin, run into cloisters and undertake to do many good works without this faith? Unbelief is called sin, as I said, but to believe on Christ — that he takes my sins upon himself, reconciles me to the Father and at the same time makes me his heir of all that is in heaven and earth — this is good works. In John 6:28-29, the Jews asked Christ: “What must we do, that we may work the works of God?” Jesus answered: “This is the work of God, that ye believe on him whom he hath sent.” Yea, and should we preach thus, who will then enter the cloisters or contribute anything for them? The purses of the monks would then surely become flat, their kitchens scanty, their cellars empty and neglected. For this reason they will not allow faith to be preached; nay, they condemn this doctrine and banish its preachers. Indeed they have already set about it in good earnest. Christ further says: “Of righteousness, because I go to the Father.”
II. THE HOLY SPIRIT CONVICTS THE WORLD OF RIGHTEOUSNESS.
6. Here all the learned come armed, yea, the whole world besides, and tell us what kind of righteousness this is. Yes, and they shall err. For the world has never known this righteousness; it does not yet know it, and it does not wish to know it. Hence, the Lord says here that the Holy Spirit will convict the world of this righteousness.
7. But what are we to understand here by “the world?” We dare not understand by it the coarse, outward sins, as adultery, murder, stealing and theft. There are instituted for such characters the wheels and gallows, with which the worldly powers, the kings, emperors and princes, have to do.
But we will interpret “the world” as the subtle and secret sins, of which the Holy Spirit convicts, which the world does not know as sin. Yea, it pronounces them divine works; it applauds them and will not permit them to be called sins. How else can unbelief and other secret sins live in the heart while the heart itself is not conscious of them and knows not that they are sins? But those who convict the world must, on that account, be reviled as heretics and be banished from the country, as we see at present.
Therefore, the Holy Spirit must convict the world.
