According to the ancient Martyrologies, St. Margaret suffered at Antioch in Pisidia, in the last general persecution. She is said to have been instructed in the Faith by a Christian nurse, to have been persecuted by her own father, a pagan priest, and, after many torments, to have gloriously finished her martyrdom by the sword. From the East, her veneration was exceedingly propagated in England, France, and Germany, in the eleventh century, during the holy wars. Her body is now kept at Monte-Fiascone in Tuscany.
ST. Margaret, holy Virgin and Martyr, thou didst faithfully preserve the robe of holy innocence and purity, valiantly resisting all the blandishments and allurements of the world for the love of thy Divine Spouse, Jesus Christ; help me to overcome all temptations against the choicest of all virtues, holy purity, and to remain steadfast in the love of Christ, in order to preserve this great gift of God. Implore for me the grace of perseverance in prayer, distrust of myself, and flight from the occasions of sin, and finally the grace of a good death, so that in Heaven I may “follow the Lamb whithersoever He goeth.” Amen
O God, grant us through the intercession of Thy holy Virgin and Martyr Margaret, undauntedly to confess the Faith, carefully to observe the chastity of our state of life, and to overcome the temptations of the world, the flesh, and the devil, and thereby escape the punishments of eternal damnation. Amen.
