Matthew 22:1-14
And Jesus answered and spoke to them again by parables and said: The kingdom of heaven is like a certain king who arranged a marriage for his son, and sent out his servants to call those who were invited to the wedding; and they were not willing to come. Again, he sent out other servants, saying, ‘Tell those who are invited, See, I have prepared my dinner; my oxen and fatted cattle are killed, and all things are ready. Come to the wedding.” ‘ But they made light of it and went their ways, one to his own farm, another to his business. And the rest seized his servants, treated them spitefully, and killed them. But when the king heard about it, he was furious. And he sent out his armies, destroyed those murderers, and burned up their city. Then he said to his servants, ‘The wedding is ready, but those who were invited were not worthy. ’Therefore go into the highways, and as many as you find, invite to the wedding.’So those servants went out into the highways and gathered together all whom they found, both bad and good. And the wedding hall was filled with guests. But when the king came in to see the guests, he saw a man there who did not have on a wedding garment. So he said to him, ‘Friend, how did you come in here without a wedding garment?’ And he was speechless. Then the king said to the servants, ‘Bind him hand and foot, take him away, and cast him into outer darkness; there will be weeping and gnashing of teeth.’ For many are called, but few are chosen.

Whenever God will try His Church, He enters into it that He may see the guests; and if He finds any one not having on the wedding garment, He enquires of him, How then were you made a Christian, if you neglect these works? Such a one Christ gives over to His ministers, that is, to seducing leaders, who bind his hands, that is, his works, and his feet, that is, the motions of his mind, and cast him into darkness, that is, into the errors of the Gentiles or the Jews, or into heresy. The nigher darkness is that of the Gentiles, for they have never heard the truth which they despise; the outer darkness is that of the Jews, who have heard but do not believe; the outermost is that of the heretics, who have heard and have learned.
