Our Mother Among the Saints, the Great Martyr Marina of Antioch in Pisidia

Troparion Tone 5
O glorious Marina betrothed to God the Word,/ thou didst abandon all things earthly/ and contest victoriously as a virgin./ For thou didst trample on the invisible foe when he appeared,/ O holy trophy-bearer,/ and thou dost now bestow gifts of healing on the world.

Kontakion Tone 3
Adorned with the beauty of virginity,/ thou hast been crowned with unfading wreaths, O Marina./ Having shed thy blood in holy martyrdom/ and radiant with miracles of healing,/ thou hast received the prize of victory from the hand of thy Creator.

From the Prolog:

Marina was born in Pisidian, Antioch of pagan parents. At the age of twelve Marina learned about the Lord Jesus Christ; how He became incarnate of the All-Pure Virgin, how He worked many miracles, how He suffered death on the Cross and gloriously resurrected. Her young heart became inflamed with love for the Lord and she vowed that she would never marry and further desired in her soul to suffer for Christ and to be baptized in the blood of martyrdom. Her father hated her because of her faith and did not consider her as his daughter. The imperial deputy Olymbrius, learning from Marina that she was a Christian, first wished that she would become his wife. When Marina rejected that he ordered her to bow down before the idols and to that St. Marina replied: “I will not bow down nor offer sacrifice to the breathless and dead idols who do not recognize themselves nor do they know that we honor or dishonor them. I will not give them that honor which belongs only to my Creator.” Then Olymbrius subjected Marina to harsh torture and threw her into prison completely covered with wounds and blood. While in prison Marina prayed to God and, after prayer, the devil appeared to her under the guise of a horrible serpent which entwined itself around her head. When she made the sign of the cross the serpent burst and vanished. Then she was engulfed with a heavenly light and it seemed to her that the walls of the prison vanished together with the roof and a radiant and towering cross appeared and atop the cross a white dove, from which a voice came saying: “Rejoice Marina, rational [discerning] dove of Christ, daughter of Zion in the highest, for your day of rejoicing has arrived.” Marina was healed from all her wounds and pains by the power of God. The demented judge tortured her the following day, both in fire and in water, but Marina endured all as though she were in another body. Finally he condemned her to be beheaded. Before her death the Lord Jesus appeared to her with angels. She was beheaded during the reign of Diocletian but in soul and power she remained alive in the heavens and on earth. A hand of St. Marina reposes in the Monastery of Vatopedi on Mt. Athos. However, atop Mt. Langa in Albania overlooking Lake Ohrid, there is a monastery dedicated to St. Marina with a portion of her miraculous relics. Countless miracles have occurred and still occur in this monastery, whose witnesses are not only Christians but many Muslims as well. So much did the Turks have respect for this holy place that they never dared disturb either this holy place or the property of this monastery. At one time a Turk was the guardian of the monastery.

From the OCA website:

The Holy Great Martyr Marina was born in Asia Minor, in the city of Antioch of Pisidia (southern Asia Minor), into the family of a pagan priest. In infancy she lost her mother, and her father gave her into the care of a nursemaid, who raised Marina in the Orthodox Faith. Upon learning that his daughter had become a Christian, the father angrily disowned her. During the time of the persecution against Christians under the emperor Diocletian (284-305), when she was fifteen years old, St Marina was arrested and locked up in prison. With firm trust in the will of God and His help, the young prisoner prepared for her impending fate.

The governor Olymbrios, charmed with the beautiful girl, tried to persuade her to renounce the Christian Faith and become his wife. But the saint, unswayed, refused his offers. The vexed governor gave the holy martyr over to torture. Having beaten her fiercely, they fastened the saint with nails to a board and tore at her body with tridents. The governor himself, unable to bear the horror of these tortures, hid his face in his hands. But the holy martyr remained unyielding. Thrown for the night into prison, she was granted heavenly aid and healed of her wounds. They stripped her and tied her to a tree, then burned the martyr with fire. Barely alive, the martyr prayed: “Lord, You have granted me to go through fire for Your Name, grant me also to go through the water of holy Baptism.”

Hearing the word “water”, the governor gave orders to drown the saint in a large cauldron. The martyr besought the Lord that this manner of execution should become for her holy Baptism. When they plunged her into the water, there suddenly shone a light, and a snow-white dove came down from Heaven, bearing in its beak a golden crown. The fetters put upon St Marina came apart by themselves. The martyr stood up in the fount of Baptism glorifying the Holy Trinity, Father, Son, and Holy Spirit. St Marina emerged from the fount completely healed, without any trace of burns. Amazed at this miracle, the people glorified the True God, and many came to believe. This brought the governor into a rage, and he gave orders to kill anyone who might confess the Name of Christ. 15,000 Christians perished there, and the holy Martyr Marina was beheaded. The sufferings of the Great Martyr Marina were described by an eyewitness of the event, named Theotimos.

Up until the taking of Constantinople by Western crusaders in the year 1204, the relics of the Great Martyr Marina were in the Panteponteia monastery. According to other sources, they were located in Antioch until the year 908 and from there transferred to Italy. Now they are in Athens, in a church dedicated to the holy Virgin Martyr. Her venerable hand was transferred to Mount Athos, to the Batopedi monastery.
