Down through the ages, the church of God proclaims the gospel of Jesus Christ to all peoples, while Satan and his angels try to drown out or confuse the good news. We celebrate the Reformation because at that time, God brought his gospel to many who thought they knew Jesus, but had fallen into trying to save themselves by the Law. In God’s Holy Word and by His Spirit, Luther and others realized the truth, written plainly and emphatically by the apostle Paul,
I am not ashamed of the gospel, because it is the power of God for the salvation of everyone who believes: first for the Jew, then for the Gentile. For in the gospel a righteousness from God is revealed, a righteousness that is by faith from first to last, just as it is written: “The righteous will live by faith.” Romans 1:16-17
The Lesson is from the book of Revelation, chapter 14, verses 6-7:
Then I saw another angel flying in midair, and he had the eternal gospel to proclaim to those who live on the earth—to every nation, tribe, language and people. He said in a loud voice, “Fear God and give him glory, because the hour of his judgment has come. Worship him who made the heavens, the earth, the sea and the springs of water.”
The Epistle lesson is from Romans, chapter 3, verses 19-28:
Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God. Therefore no one will be declared righteous in God’s sight by the works of the law; rather, through the law we become conscious of our sin.
But now apart from the law the righteousness of God has been made known, to which the Law and the Prophets testify. This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile, for all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus. God presented Christ as a sacrifice of atonement, through the shedding of his blood—to be received by faith. He did this to demonstrate his righteousness, because in his forbearance he had left the sins committed beforehand unpunished — he did it to demonstrate his righteousness at the present time, so as to be just and the one who justifies those who have faith in Jesus.
Where, then, is boasting? It is excluded. Because of what law? The law that requires works? No, because of the law that requires faith. For we maintain that a person is justified by faith apart from the works of the law.
The Gospel for the Festival of the Reformation is from John, chapter 8, verses 31-36:
To the Jews who had believed him, Jesus said, “If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.”
They answered him, “We are Abraham’s descendants and have never been slaves of anyone. How can you say that we shall be set free?”
Jesus replied, “Very truly I tell you, everyone who sins is a slave to sin. Now a slave has no permanent place in the family, but a son belongs to it forever. So if the Son sets you free, you will be free indeed.
