Luther's Sermons - Matthew 22:1-14.
Twentieth Sunday after Trinity
19. Now the wedding garment is Christ himself, which is put on by faith, as the Apostle says in Romans 13:14: “Put ye on the Lord Jesus Christ.” Then the garment gives forth a luster of itself, that is, faith in Christ bears fruit of itself, namely, love which works through faith in Christ. These are the good works, that also flash forth from faith, and entirely gratuitously do they go forth, they are done alone for the good of our neighbor; otherwise they are heathenish works, if they flow not out of faith; they will later come to naught and be condemned, and be cast into the outermost darkness.
21. The mistake is also readily observed here, by which many have perverted the Gospel in that they say: Although the Pope and his following are wicked, yet we must obey him and acknowledge him as the head of Christendom. Let him do what he may, and yet he cannot err, and although he may not have on the wedding garment, nevertheless he is in the congregation. But they are not so good that one might compare them to the one who had not on the wedding garment. They are the villains and murderers who killed the servants of the King; and even if they were worthy to be compared to him, yet the Gospel in this parable does not teach us to follow them, but to cast them out and protect ourselves against them. For whoever has not on the wedding garment does not belong to the congregation, is filth, like the slime, pus, and ulcers in the body; it is indeed in the body, but it is no part of the healthy body. Counterfeits are among money, but they are not money; chaff is among the wheat, but it is not wheat; so these are among Christians, but they are not Christians. This is sufficient on today’s Gospel. Let us pray God for grace, that none of us may come to such a precious and glorious marriage feast without a wedding garment.
6. And when Thy glory I shall see
And taste Thy kingdom's pleasure,
Thy blood my royal robe shall be,
My joy beyond all measure.
When I appear before Thy throne,
Thy righteousness shall be my crown,-
With these I need not hide me.
And there, in garments richly wrought
As Thine own bride, I shall be brought
To stand in joy beside Thee.
