Matthew 22:11

Wedding garment, which Calvin erroneously understands of faith, for he came by faith to the nuptials. St. Augustine says it is the honour and glory of the spouse, which each one should seek, and not his own; and he shews this, in a sermon on the marriage feast, to be charity. This is the sentiment of the ancients, of St. Gregory, St. Ambrose, and others. What St. John Chrysostom expounds it, viz. an immaculate life, or a life shining with virtues, and free from the filth of sin, is nearly the same; for charity cannot exist without a good life, nor the purity of a good life, without charity. In his 70th homily on St. Matthew, he says that the garment of life is our works; and this is here mentioned, that none might presume, (like Calvin and his followers) that faith alone was sufficient for salvation. When, therefore we are called by the grace of God, we are clothed with a white garment, to preserve which from every stain, from every grievous sin, depends upon the diligence (the watching and praying) of every individual. (St. John Chrysostom) --- It was the custom then, as it still is in every civilized nation, not to appear at a marriage feast, or at a dinner of ceremony, except in the very best attire.
