Saint Helen was the mother of St Contantine the Great, and was probably born at Drepanum (Helenopolis) in Asia Minor to parents of humble means. She married Constantius Chlorus, and their son Constantine was born in 274. Constantius divorced her in 294 in order to further his political ambition by marrying a woman of noble rank. After he became emperor, Constantine showed his mother great honor and respect, granting her the imperial title “Augusta.”
After Constantine became the sole ruler of the Western Roman Empire, he issued the Edict of Milan in 313 which guaranteed religious tolerance for Christians. St Helen, who was a Christian, may have influenced him in this decision. In 323, when he became the sole ruler of the entire Roman Empire, he extended the provisions of the Edict of Milan to the Eastern half of the Empire. After three hundred years of persecution, Christians could finally practice their faith without fear.
The emperor deeply revered the victory-bearing Sign of the Cross of the Lord, and also wanted to find the actual Cross upon which our Lord Jesus Christ was crucified. For this purpose he sent his own mother, the holy Empress Helen, to Jerusalem, granting her both power and money. Patriarch Macarius of Jerusalem and St Helen began the search, and through the will of God, the Life-Creating Cross was miraculously discovered in 326. (The account of the finding of the Cross of the Lord is found under the Feast of the Exaltation of the Cross, September 14). The Orthodox Church commemorates the Uncovering of the Precious Cross and the Precious Nails by the Holy Empress Helen on March 6.
While in Palestine, the holy empress did much of benefit for the Church. She ordered that all places connected with the earthly life of the Lord and His All-Pure Mother, should be freed of all traces of paganism, and she commanded that churches should be built at these places.
The emperor Constantine ordered a magnificent church in honor of Christ’s Resurrection to be built over His tomb. St Helen gave the Life-Creating Cross to the Patriarch for safe-keeping, and took part of the Cross with her for the emperor. After distributing generous alms at Jerusalem and feeding the needy (at times she even served them herself), the holy Empress Helen returned to Constantinople, where she died in the year 327.
Because of her great services to the Church and her efforts in finding the Life-Creating Cross, the empress Helen is called “the Equal of the Apostles.”
