Holy Great-Martyr Barbara
This glorious follower of Christ was betrothed to Christ from early childhood. Her father Dioscorus was a pagan and was renowned for his position and wealth in the city of Heliopolis in Egypt. Dioscorus locked up his only daughter Barbara, brilliant in mind and of beautiful countenance, in a high tower.
He surrounded her with every comfort, gave her female servants, erected idols for worship, and built her a bathing room with two windows. Looking through the window at the earth below and the starry heavens above, Barbara's mind was opened by the grace of God. She recognized the One True God, the Creator, despite the fact that she did not have a human teacher to bring her to this knowledge. Once, while her father was away from the city, she came down from the tower and, according to God's providence, met some Christian women who revealed the true Faith of Christ to her. Barbara's heart became inflamed with love for Christ the Lord. She ordered that a third window be cut open in the bath so that the three windows would represent the Holy Trinity. On one wall she traced a Cross with her finger, and the Cross etched itself deep in the stone as if cut by a chisel. A pool of water sprang forth from her footprints on the floor of the bath, which later gave healing of diseases to many.
Learning of his daughter's faith, Dioscorus beat her severely and drove her from the tower. He pursued her in order to kill her, but a cliff opened up and hid Barbara from her brutal father. When she appeared again, her father brought her to Martianus, the magistrate, who handed her over for torture. They stripped the innocent Barbara and flogged her until her entire body was covered with blood and wounds, but the Lord Himself appeared to her in prison with His angels and healed her. A certain woman, Juliana, upon seeing this, desired martyrdom for herself. Both women were severely tortured and with mockery were led through the city. Their breasts were cut off and much blood flowed from them. They were finally led to the place of execution, where Dioscorus himself slaughtered his daughter, and Juliana was slain by the soldiers. That same day, lightning struck the house of Dioscorus, killing him and Martianus. St. Barbara suffered in the year 306. Her miracle-working relics rest in Kiev. Glorified in the Kingdom of Christ, she has appeared many times even in our own day, sometimes alone and sometimes in the company of the Most-holy Theotokos.
