Esther 8:15

The glory of the holy teachers is exalted because it is through their doctrine and exhortation that the faithful defeat the cruelty of their most evil enemy with the help and strength of their heavenly king. And their reward remains with them in the heavenly kingdom of eternal blessedness and perpetual splendor, which appears to be signified by the colors of blue and white and the brightness of gold.

It is to the great credit of our sacred teachers that with their teaching and encouragement the faithful are able to conquer, through the power of the supreme king, the savagery of a most wicked enemy; and their reward for this awaits them in the heavenly kingdom of eternal blessing and perpetual brightness, which seem to be prefigured by the color blue and the flash of gold. Moreover, in the celestial citadel the martyrs of Christ, along with those who are going to rule together with Christ the king, are repaid with the dignity given to kings by that most righteous of source of recompense, in exchange for shedding their blood. The terms "purple" and "silken" offer us a prefiguration of this fact; and every gathering of saints will be happy and rejoice no less over this in the celestial Jerusalem. This is described in what follows: "So for the Jews, a new light was seen to arise; and joy, and honor, and celebration. Among every people, city and province, and wherever the king's orders reached, there was a wonderful exultation, banquets, and feasting, and a holiday; and so much so that many members of other nations and beliefs adopted their religion and their rites. For a great terror of the Jewish people had fallen upon them all." Many, therefore, among the gentiles and enemies of the Church left behind their idolatry and their gentile superstitions, and were converted to the Christian faith by the power, wisdom and perseverance of the holy martyrs, and through the virtue of Christ that shines through them; which should be perfectly obvious to anyone who reads about the sufferings of the saints and the triumphs of the martyrs. And since that time, the numbers of the faithful have been growing every day by the mercy of God, and the precincts of the Church have been replenished. This is mentioned by the Psalmist: "Let all the land fear the Lord; let everyone be moved by him, and all who inhabit the world" (Psalms 33). And likewise: "The righteous will rejoice in the Lord and will hope in him; and all the upright in heart will be praised" (Psalms 64). And the apostle says: "In the name of Jesus every creature—celestial, terrestrial and infernal—shall bend his knee, and every tongue shall proclaim that the Lord Jesus is in the glory of God the Father" (Philippians 2).
