"The Martyr Barbara, who was called by God..."

St. Barbara the Great Martyr (source)

  
The Martyr Barbara, who was called by God, said as she suffered in the stadium: "Though the current tortures are terrible, O judge, I would not trade the things of heaven for those of the earth. Therefore, cut, tear apart the flesh, and deliver me over to fire, while I rejoice to depart for Christ, my Bridegroom." Through her intercessions, Savior, send down upon us Your mercies, and save those who celebrate her struggle with faith.
-Idiomelon of the Praises, in the Second Tone, by Byzantios.

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
