Saint Helena of Constantinople

Life and historical context

Flavia Iulia Helena was born around the year 248 in Drepanum, a small town on the Sea of Marmara in the Roman province of Bithynia (modern Hersek in Turkey). The early sources are unanimous that her social origin was modest. The historian Procopius and the Christian writer Saint Ambrose of Milan both describe her as having been born of humble parentage; Saint Ambrose, writing within a generation of her death, calls her a stabularia, an innkeeper or stable-girl. Her marriage to the Roman officer Constantius Chlorus, around 270, raised her to the highest social levels of late third-century Rome.1

She bore Constantius a single son, Constantine, around the year 272. When Constantius was made Caesar (junior emperor) in the Diocletianic Tetrarchy in 293, the political requirements of his new station led him to repudiate Helena and to marry Theodora, the stepdaughter of the senior Augustus Maximian. Helena remained in obscurity for the next two decades while Constantius rose first to Augustus (senior emperor of the West) and then died at York in 306. Her son Constantine was at his father's side at the moment of death and was acclaimed Augustus by the army.

Constantine's rise to sole rule of the Roman world (completed in 324 with the defeat of Licinius) restored Helena to public prominence. She was named Augusta (the highest female imperial title) around 325, her image was placed on the imperial coinage, and she was given full access to the imperial treasury. Her conversion to Christianity, traditionally placed in the years following the Edict of Milan (313), was sincere and complete. Eusebius of Caesarea, in his Life of Constantine (composed around 339), describes her late-life pilgrimage to the Holy Land, undertaken probably between 326 and 328 when Helena was approximately seventy-eight years old, as the principal expression of her Christian devotion.2

The pilgrimage produced two major lasting consequences. First, Helena commissioned the construction of churches at the principal sites of Christian salvation history: the Basilica of the Nativity at Bethlehem (over the cave of the Lord's birth) and the Basilica of the Eleona on the Mount of Olives (over the cave of the Ascension). Both churches were largely destroyed in the seventh-century Persian and later Arab invasions but rebuilt and remain among the principal Christian pilgrimage sites of the Holy Land. Second, the Catholic tradition (attested from the late fourth century onward in writers including Saint Ambrose, Rufinus of Aquileia, and Sulpicius Severus) credits Helena with the discovery of the True Cross, the wood of the Lord's crucifixion, beneath the site of a Roman temple to Venus that Hadrian had built over the location of Calvary in the second century.3

She died around the year 330, probably at Nicomedia, in the presence of her son. Her body was returned to Rome and laid to rest in a porphyry sarcophagus (now preserved in the Vatican Museums) in the mausoleum she had built for herself on the Via Labicana. Constantine's preservation of her relics, his patronage of the churches she had founded, and his elevation of her to imperial sanctity were the foundations of her enduring cult in the Catholic and Orthodox East and in the Latin West.

Theological and spiritual significance

The veneration of Saint Helena rests principally on her role as the Christian mother of the first Christian emperor and as the discoverer of the True Cross. The Catholic doctrine of relics, defined and elaborated by the Second Council of Nicaea (787) and clarified in the Council of Trent's Session XXV (1563), holds that the bodies of the saints and the instruments of Christ's Passion (the True Cross, the Crown of Thorns, the Holy Nails, the Shroud, and others) are worthy of due veneration in the Catholic Church. The historical reliability of the Helena tradition concerning the True Cross is debated by modern scholars, but the substantive Catholic conviction about the relics of the Passion does not depend on the historical particulars of any one discovery account.4

Helena's veneration as a saint developed quickly in the Eastern Church. She is honored in the Byzantine liturgy as Equal-to-the-Apostles, a title shared with her son Constantine, in recognition of their joint role in the Christianization of the Roman Empire. The Western veneration developed more slowly but became universal by the early Middle Ages. Her feast was placed in the Roman Martyrology by Pope Saint Pius V in the sixteenth century and is observed today on 18 August in the universal Roman Calendar with the rank of optional memorial.

The relics traditionally associated with her discovery (fragments of the True Cross and of the nails of the Crucifixion) are venerated across the Catholic world in many basilicas: at the Basilica of the Holy Cross in Jerusalem in Rome (founded by Helena herself in her own Roman palace, the Sessorian Palace, on her return from the Holy Land), at the Basilica of Saint Peter in the Vatican, at the Cathedral of Trier, at the Cathedral of Notre-Dame in Paris (until the 2019 fire), and at many other Catholic shrines. The historical authenticity of any individual relic is a matter of ecclesiastical and scholarly judgment, but the Catholic veneration of relics of the True Cross as a class is doctrinally well-established.

Devotion and liturgical observance

The feast of Saint Helena is celebrated on 18 August in the universal Roman Calendar with the rank of optional memorial. In the Eastern Catholic Churches and the Eastern Orthodox tradition, she is honored together with her son Constantine on 21 May with the rank of feast. The Catholic Church distinguishes between the joint Constantinian feast and the proper feast of Helena alone, but both observances are kept.

The principal pilgrimage destinations associated with Saint Helena are the Basilica of the Holy Cross in Jerusalem in Rome (the church built by Helena in her own palace to house the relics she brought from the Holy Land, with a chapel dedicated to her, the Cappella di Santa Elena), the Basilica of the Holy Sepulchre in Jerusalem (the great Constantinian church built over the site of the Crucifixion and Resurrection), and the Cathedral of Trier in Germany (which preserves the Holy Robe of Christ traditionally associated with her).

The traditional iconography of Saint Helena shows her in imperial Byzantine vestments with the imperial crown, holding a large processional cross or one of the nails of the Crucifixion. She is frequently depicted in pendant with her son Constantine, both holding a cross between them, in the iconography proper to the Eastern Equal-to-the-Apostles. Her liturgical color on the feast is white.

Prayers and novenas associated with Saint Helena

The principal devotion to Saint Helena is the Novena to Saint Helena, prayed for the resolution of difficult marriages (in connection with her own painful experience of repudiation by Constantius), for the protection of converts to the faith, for archaeologists and those engaged in the search for historical truth, and for the recovery of lost or hidden treasures. The novena is most commonly prayed in the nine days leading up to her feast on 18 August.

A traditional brief invocation associated with Saint Helena, in connection with the True Cross:

Saint Helena, who through your prayers and labors recovered the wood of our salvation, intercede for us, that we may take up our crosses and follow your son's Lord into the Kingdom.

Catholics commonly pair Saint Helena devotions with the Stations of the Cross, the Sorrowful Mysteries of the Holy Rosary, and the Memorare. For the broader theological context, see Communion of Saints and the Catholic doctrine of relics.
