Matthew 22:11

To see (RV 'behold') the guests] The scene changes to the last judgment, when the fitness of the guests to be there will be the subject of a solemn scrutiny. Theophylact well says, 'The entrance to the marriage feast is without scrutiny, for by grace alone were we all called, both good and bad. But the subsequent life of those who have entered in, will not be without scrutiny, but the King will make a most exact scrutiny of those who after their entry into the faith, shall be found with filthy garments. Let us therefore tremble, reflecting that unless a man live a pure life, faith by itself is of no avail, for not only is he cast out of the marriage feast, but is cast into the fire.' A wedding garment] Eastern etiquette is strict, and to appear without the festive garment that custom prescribes, would be a serious offence. Since the judgment is according to works, the wedding garment is not faith, or imputed righteousness, but a holy life.
