St. Margaret's feast has been supressed because there is not much historical information about her life. There was great devotion to this saint, especially during the Middle Ages. She is one of the "Fourteen Holy Helpers" and one of the saints that appeared and spoke to St. Joan of Arc.

"This same day brings before us a rival of the warrior-martyr, St. George: Margaret, like him victorious over the dragon, and like him called in the Menaea of the Greeks, the Great Martyr. The cross was her weapon; and, like the soldier, the virgin, too, consummated her trial in her blood. They were equally renowned in those chivalrous times when valor and faith fought hand in hand for Christ beneath the standard of the saints. So early as the seventh century our Western island rivaled the East in honoring the pearl drawn from the abyss of infidelity. Before the disastrous schism brought about by Henry VIII, the Island of Saints celebrated this feast as a double of the second class; women alone were obliged to rest from servile work, in gratitude for the protection afforded them by St. Margaret at the moment of childbirth—a favor which ranked her among the saints called in the Middle Ages auxiliaries or helpers. But it was not in England alone that Margaret was invoked, as history proves by the many and illustrious persons of all countries who have borne her blessed name."

 Hymn from the Common or Feast

 Son of a virgin, maker of thy mother,
 Thou, rod and blossom from a stem unstainèd,
 Now while a virgin fair of fame we honour,
 Hear our devotion!

 Lo, on thy handmaid fell a two-fold blessing,
 Who, in her body vanquishing the weakness,
 In that same body, grace from heaven obtaining,
 Bore the world witness.

 Death, nor the rending pains of death appalled her;
 Bondage and torment found her undefeated:
 So by the shedding of her blood attained she
 Heavenly guerdon.

 Fountain of mercy, hear the prayers she offers;
 Purge our offences, pardon our transgressions,
 So that hereafter we to thee may render
 Praise with thanksgiving.

 Thou, the All-Father, thou, the One-Begotten,
 Thou, Holy Spirit, Three in One co-equal,
 Glory be henceforth thine through all the ages,
 World without ending.
 Amen.

Continuation of the Holy Gospel according to Matthew
R. Glory be to Thee, O Lord.
Matt 25:1 - 13.
 At that time Jesus spoke this parable to His disciples: "Then will the kingdom of heaven be like ten virgins who took their lamps and went forth to meet the bridegroom and the bride. Five of them were foolish and five wise. But the five foolish, when they took their lamps, took no oil with them, while the wise did take oil in their vessels with the lamps. Then as the bridegroom was long in coming, they all became drowsy and slept. And at midnight a cry arose, 'Behold, the bridegroom is coming, go forth to meet him!' Then all those virgins arose and trimmed their lamps. And the foolish said to the wise, 'Give us some of your oil, for our lamps are going out.' The wise answered, saying, 'Lest there may not be enough for us and for you, go rather to those who sell it, and buy some for yourselves.' Now while they were gone to buy it, the bridegroom came; and those who were ready went in with him to the marriage feast, and the door was shut. Finally there came also the other virgins, who said, 'Sir, sir, open the door for us!' But he answered and said, 'Amen I say to you, I do not know you.' Watch therefore, for you know neither the day nor the hour."
R. Praise be to Thee, O Christ.
S. By the words of the Gospel may our sins be blotted out.

Thank you both for these beautiful images and prayers.
