{4} And when the king came in to see the guests, he saw there a man which had not on a wedding garment:

(4) In the small number which come at the calling, there are some castaways who do not confirm their faith with newness of life.

People's New Testament

22:11 Saw there a man which had not a wedding garment. It is said to be a custom in the East, even at the present day, for the host to present his guests with robes of honor. Every saint is robed, not in his own righteousness, but in the white robes of Christ's righteousness. As many of you as have been baptized into Christ have put on Christ (Ga 3:27). Abbott, on this passage says:

The garments we put on when he put on the Lord Jesus Christ by faith in baptism... To be without the wedding garments, offered freely to him, implied that the man thought his usual attire good enough. He therefore represents one who, while professing to be for Christ, thought his own righteousness would save him without a trustful obedience to the Savior (Ro 13:14 Ga 3:26-27).''

Wesley's Notes

22:11 The guest - The members of the visible Church.

Jamieson-Fausset-Brown Bible Commentary

11. And when the king came in to see the guests-Solemn expression this, of that omniscient inspection of every professed disciple of the Lord Jesus from age to age, in virtue of which his true character will hereafter be judicially proclaimed!

he saw there a man-This shows that it is the judgment of individuals which is intended in this latter part of the parable: the first part represents rather national judgment.

which had not on a wedding garment-The language here is drawn from the following remarkable passage in Zep 1:7, 8:-"Hold thy peace at the presence of the Lord God; for the day of the Lord is at hand: for the Lord hath prepared a sacrifice, He hath bid His guests. And it shall come to pass in the day of the Lord's sacrifice, that I will punish the princes, and the king's children, and all such as are clothed with strange apparel." The custom in the East of presenting festival garments (see Ge 45:22; 2Ki 5:22), even though nor clearly proved, Is certainly presupposed here. It undoubtedly means something which they bring not of their own-for how could they have any such dress who were gathered in from the highways indiscriminately?-but which they receive as their appropriate dress. And what can that be but what is meant by "putting on the Lord Jesus," as "The Lord Our Righteousness?" (See Ps 45:13, 14). Nor could such language be strange to those in whose ears had so long resounded those words of prophetic joy: "I will greatly rejoice in the Lord, my soul shall be joyful in my God; for He hath clothed me with the garments of salvation, He hath covered me with the robe of righteousness, as a bridegroom decketh himself with ornaments, and as a bride adorneth herself with her jewels" (Isa 61:10).

Matthew Henry's Concise Commentary

22:1-14 The provision made for perishing souls in the gospel, is represented by a royal feast made by a king, with eastern liberality, on the marriage of his son. Our merciful God has not only provided food, but a royal feast, for the perishing souls of his rebellious creatures. There is enough and to spare, of every thing that can add to our present comfort and everlasting happiness, in the salvation of his Son Jesus Christ. The guests first invited were the Jews. When the prophets of the Old Testament prevailed not, nor John the Baptist, nor Christ himself, who told them the kingdom of God was at hand, the apostles and ministers of the gospel were sent, after Christ's resurrection, to tell them it was come, and to persuade them to accept the offer. The reason why sinners come not to Christ and salvation by him, is, not because they cannot, but because they will not. Making light of Christ, and of the great salvation wrought out by him, is the damning sin of the world. They were careless. Multitudes perish for ever through mere carelessness, who show no direct aversion, but are careless as to their souls. Also the business and profit of worldly employments hinder many in closing with the Saviour. Both farmers and merchants must be diligent; but whatever we have of the world in our hands, our care must be to keep it out of our hearts, lest it come between us and Christ. The utter ruin coming upon the Jewish church and nation, is here represented. Persecution of Christ's faithful ministers fills up the measure of guilt of any people. The offer of Christ and salvation to the Gentiles was not expected; it was such a surprise as it would be to wayfaring men, to be invited to a royal wedding-feast. The design of the gospel is to gather souls to Christ; all the children of God scattered abroad, Joh 10:16; 11:52. The case of hypocrites is represented by the guest that had not on a wedding-garment. It concerns all to prepare for the scrutiny; and those, and those only, who put on the Lord Jesus, who have a Christian temper of mind, who live by faith in Christ, and to whom he is all in all, have the wedding-garment. The imputed righteousness of Christ, and the sanctification of the Spirit, are both alike necessary. No man has the wedding-garment by nature, or can form it for himself. The day is coming, when hypocrites will be called to account for all their presumptuous intruding into gospel ordinances, and usurpation of gospel privileges. Take him away. Those that walk unworthy of Christianity, forfeit all the happiness they presumptuously claimed. Our Saviour here passes out of the parable into that which it teaches. Hypocrites go by the light of the gospel itself down to utter darkness. Many are called to the wedding-feast, that is, to salvation, but few have the wedding-garment, the righteousness of Christ, the sanctification of the Spirit. Then let us examine ourselves whether we are in the faith, and seek to be approved by the King.
