Who Was St. Nicholas of Myra? The Bishop Behind the Legends

Few saints are loved by more people who know less about them. Every December his name is on cards, in songs, and attached to a red-coated figure who comes down chimneys. In Orthodox churches on 6 December the faithful sing of a bishop who was "a rule of faith, a model of meekness, and a teacher of temperance." Between the two lie centuries of stories told, retold and improved, from a late antique account of a bishop who stopped an execution to a late medieval legend of a bishop who struck a heretic at Nicaea.

Who was St Nicholas of Myra? The honest answer begins with a point even sympathetic scholars concede: almost nothing about him is documented in his own lifetime, so a careful Christian should know which stories come from where. This article tells the life as the Church remembers it, sorts the sources from oldest to latest, and asks what remains.

In brief

By the unanimous memory of the Church, Nicholas was a bishop of Myra in Lycia, in the first half of the fourth century. No document from his lifetime mentions him. The earliest surviving account, the Praxis de stratelatis ("The Deed concerning the Generals"), is dated by its modern editor to between 460 and 580; it tells how Nicholas saved three innocent men from execution and three falsely condemned generals by his intercession. In the sixth century Justinian built a shrine to a St Nicholas in Constantinople. The first full Life, by Michael the Archimandrite, comes from the early ninth century, about five hundred years after his death, and gives the story of the gold thrown through a window. His presence at Nicaea is asserted by some early sources and missing from others. The slap first appears, in the earliest text yet identified, in a fourteenth-century Latin text about "a certain Arian." His relics were taken to Bari in 1087. Santa Claus is a nineteenth-century American figure who borrowed his name.

Thesis: St Nicholas was very probably a real fourth-century bishop of Myra remembered for defending the helpless, but nearly every detail of his life comes from much later tradition, so an honest Orthodox Christian can venerate him wholeheartedly while holding the stories, especially the slap at Nicaea, with an open hand.

The life as the Church tells it

The life published by the Orthodox Church in America, retelling the traditional Life, begins in Patara in Lycia. Nicholas was the only son of pious, long-childless parents, Theophanes and Nonna. As a newborn he stood in the baptismal font for three hours, "thereby honoring the Most Holy Trinity." His uncle, the bishop of Patara, ordained him reader and then priest.¹

A ruined neighbor was about to sell his three daughters into prostitution. Nicholas, who had given away his inheritance, came by night and threw a bag of gold through the window, and later did the same for the other daughters. The ninth-century Life adds that on the third night the father ran after him and fell at his feet, and Nicholas bound him by oath never to tell.² After a pilgrimage to the Holy Land he came to Myra, where, as the bishops sought a new archbishop, one of the elder bishops was told in a vision that the first man to enter the church that night, named Nicholas, should be made archbishop.

Imprisoned under Diocletian and released under Constantine, he went in 325 to the First Ecumenical Council at Nicaea, where, the OCA life says, he "assailed the heretic Arius with his words, and also struck him upon the face." Deprived of the signs of his office, he was restored when several Fathers saw Christ and the Mother of God returning his Gospel and omophorion.³ He snatched an executioner's sword from above three condemned men, appeared in a dream to Constantine to save three generals, rescued sailors and fed Myra in a famine. He died in old age, and his relics "flowed with curative myrrh." In 1087 they were taken to Bari in Italy.

The primary historical evidence

The documents behind this story come in layers, each separated from Nicholas by centuries. Almost all were edited in Greek by Gustav Anrich in Hagios Nikolaos (1913 and 1917); the quotations below come from English translations of Anrich's texts published by Roger Pearse.

The oldest layer: the Praxis de stratelatis

Anrich dated the Praxis to between 460 and 580; Karl Meisen placed it in the sixth century.⁴ Gerardo Cioffari, of the Centro Studi Nicolaiani at the Basilica of St Nicholas in Bari and a defender of the saint's historicity, argues that the Constantinopolitan priest Eustratios already drew on an ancient Life of Nicholas in 583.⁵

The story is vivid and local. Three generals, Nepotianus, Ursus and Herpylion, sent by Constantine against a revolt of the Taifali in Phrygia, put in at Andriake, the port of Myra. Meanwhile the governor Eustathius, bribed, condemns three citizens to death. Nicholas runs through named places in the city, past the shrine of the martyrs Crescens and Dioscorides, finds the men kneeling and blindfolded, and "snatched the sword, and threw it right away."⁶ Later the generals, slandered at court, are condemned without trial. One prays to "the Lord, God of your servant Nicholas," and that night Nicholas appears to Constantine in a dream: "I am the sinner, bishop Nicholas," he says, "I am in Myra, metropolis of Lycia."⁷

{{moderate: The Praxis knows real people and places of Constantine's reign.}} The translation's notes observe that Constantine resettled Taifali in Phrygia and that their revolt in 336 was put down by generals with these names; Ablabius, the prefect in the story, was consul in 331.⁸ A legend can borrow real names, so this shows the story is old and rooted in Lycia, not that every detail happened.

A sixth-century cult

Procopius records that the Emperor Justinian "established a shrine to St. Priscus and St. Nicholas, an entirely new creation of his own," on the waterfront of Constantinople.⁹ The 1911 Catholic Encyclopedia takes this as a church in honor of Nicholas of Myra, the natural reading, though Procopius does not say which Nicholas.¹⁰

The ninth-century Lives

The first full biography, by Michael the Archimandrite, is dated by its translators between 814 and 842.¹¹ It contains the three daughters, the sailors, the grain ships and the temple of Artemis, and it treats the story of the generals as already familiar. Michael is candid: his picture of the saint came from a devout monk, and "an account has come down from the beginning, which has its origin in tradition." No one could give an accurate account, he admits, because "one person tells of one and another person tells of another" miracle.¹²

Another ninth-century Greek Life, attributed to a certain Methodius, identified by some with the patriarch of Constantinople of that name (d. 847), became the main source of the Latin Life written in Naples by John the Deacon around 880, from which all later Latin Lives derive.¹³ In time these stories were merged, without any intent to deceive, with those of a different man: St Nicholas of Sion, a sixth-century archimandrite of Holy Sion in Lycia and later bishop of Pinara. A Byzantine compilation of the ninth or tenth century, the Vita Compilata, already draws on the Life of Nicholas of Sion, "an unrelated saint."¹⁴ The detail in the familiar life that Nicholas entered "a monastery named Holy Sion, which had been founded by his uncle" is probably a trace of that merger.

What can we actually verify?

(a) Contemporary or near-contemporary evidence

There is none. No fourth-century letter, inscription, chronicle or council record names Nicholas of Myra. The Catholic Encyclopedia concluded that "there is scarcely anything historically certain about him except that he was Bishop of Myra in the fourth century." {{strong: That a bishop named Nicholas led the church of Myra in the early fourth century and was venerated there after his death is a reasonable historical judgment.}} His dates are uncertain: the Catholic Encyclopedia gives his death as 6 December 345 or 352; the Oxford news release mentioned below says some historians place it "around 343."¹⁵

Was he at Nicaea? The Catholic Encyclopedia notes that "his name is not mentioned in any of the old lists of bishops that attended this council." Cioffari replies that Theodore the Lector affirmed his participation around 515, probably drawing on the ancient Life rather than a council list. The translators of Michael's Life note that his name appears only in later lists of attendees, "themselves of doubtful accuracy."¹¹ The surviving lists are incomplete, so silence is not proof of absence. Neither Michael's Life nor the eighth-century encomium attributed to Andrew of Crete, which praises Nicholas for lifting "the sword of faith" against Arius, places him at the council.¹⁶ By the ninth or tenth century the Vita Compilata has him speaking "in the first great synod in Nicaea." {{debated: Nicholas's presence at Nicaea is possible, and an early tradition asserts it, but no fourth-century source confirms it.}}

(b) Later hagiographical tradition

The dowry. The three daughters first appear in a surviving text in Michael's Life. Cioffari calls the story "historical in its essentials" because very different early versions exist, but his own description shows how much it moved: in the Sinai version there are two girls and the boy Nicholas takes money from his living parents; the Ethiopic version has four girls; the Byzantine, adopted in the West, three. A kernel of remembered generosity is plausible; the details are not recoverable.

The slap. Here the evidence is clearest, and it tells against the legend. Working through the testimonia in Anrich, Pearse found the earliest form in a Latin text by Petrus de Natalibus, a Venetian who was bishop of Equilio (Jesolo) in 1370 and died around 1400. It begins fertur, "it is said," and reports that Nicholas, already old, struck "a certain Arian" (quemdam Arrianum) on the jaw and lost his mitre and pallium. The next witness is a Greek Life by Damaskenos the Monk, first printed in Venice in 1570, where the blow lands on Arius himself, followed by prison and the vision of Christ and the Theotokos restoring his Gospel and omophorion.¹⁷ The scene later entered the eighteenth-century icon painters' manual of Mount Athos by Dionysius of Fourna. John Sanidopoulos places it among undated later interpolations in John the Deacon's Latin Life of about 880; it is absent from Pearse's edition of that Life, made from the earliest manuscripts. {{strong: No known source earlier than the fourteenth century tells of Nicholas striking anyone at Nicaea.}} The story may echo his remembered zeal against Arianism; as a report of an event in 325 it has no support.

(c) Reported miracles and the relics

Most of the miracles are told only in the ninth-century and later Lives. The oldest is his appearance in dreams to Constantine and Ablabius in the Praxis, which already shows Christians asking the prayers of a holy bishop who was not present. Michael reports that after burial his body "straightaway gushed forth a sweet-smelling perfume."¹⁸ The liquid gathered from his tomb in Bari, the manna of St Nicholas, is in the Catholic Encyclopedia's careful words "said to flow." These are reports that historians cannot test.

The removal of the relics is, by contrast, one of the best-documented events in the story. In 1087 sailors and merchants of Bari landed at Myra, bound the monks guarding the tomb, and carried the bones home; the OCA account dates the opening of the tomb to 20 April and the solemn reception in Bari to 9 May.¹⁹ Charles W. Jones observed that "practically every Western chronicler of the generation reported this event of 1087," and two detailed accounts were written in Bari, by the Benedictine monk Nicephorus and by John, archdeacon of Bari.²⁰ In 2017 Oxford researchers radiocarbon-dated a pelvis fragment, originally from Lyon, to the fourth century. Professor Tom Higham was careful: "Science is not able to definitely prove that it is, it can only prove that it is not."¹⁵ The result fits the tradition; it does not prove it.

The Orthodox position

Dogma. The Church teaches that the saints are alive in Christ and pray for us, and that their relics and icons may be honored; see Why Do Orthodox Christians Pray to Saints? and our guide to icons and relics. No council has defined anything about the details of Nicholas's life.

Common tradition. That Nicholas was a holy bishop of Myra, a defender of the poor and the falsely accused, and a powerful intercessor is the unbroken tradition of East and West. His feast is 6 December (19 December on the civil calendar for churches keeping the Julian calendar); the OCA also lists his nativity on 29 July and the translation of his relics on 9 May.²¹ The May feast is kept above all in the Russian tradition; the same OCA account says "the Greek Church did not establish the celebration of this remembrance, since they regarded the loss of the relics of Saint Nicholas as a sad event." On how the Church recognizes saints, see How Does Someone Become a Saint in the Orthodox Church?

Notice which story the Church's hymn chooses. The kontakion for 6 December praises him "for you fulfilled the Gospel of Christ, O Venerable Nicholas, by laying down your life for your people, / and saving the innocent from death."²² That is the oldest story in the record, not the slap.

Theological opinion and historical judgment. Whether he attended Nicaea, which miracles happened as told, and how much of his Life belongs to Nicholas of Sion are open questions on which Orthodox Christians may follow the evidence. And even if the slap happened, the Church's canons would not commend it: Canon 27 of the Apostolic Canons orders that a bishop who strikes the faithful who have sinned, or unbelievers who have done wrong, "with the intention of frightening them" be deposed, because Christ "when he was smitten he smote not again."²³ The legend's point was his zeal for the truth about Christ that Nicaea defended (see our guides to who Arius was and the Council of Nicaea), not a license to answer error with fists.

The road to Santa Claus

Nicholas, long a patron of children, became a midwinter gift-bringer in Western Europe in the High Middle Ages,²⁴ and in Germany, Switzerland and the Netherlands, as the Catholic Encyclopedia put it, "the secret purveyor of gifts to children on 6 December." The gold through the window fits Christ's command: "when you do a charitable deed, do not let your left hand know what your right hand is doing, that your charitable deed may be in secret" (Matthew 6:3-4, NKJV).

The American Santa Claus is another matter. In editions of Washington Irving's comic History of New York (first published 1809), St Nicholas comes "riding over the tops of the trees, in that self-same wagon wherein he brings his yearly presents to children."²⁵ In 1823 the Troy Sentinel printed, anonymously, "A Visit from St. Nicholas," with its eight reindeer and its "chubby and plump, a right jolly old elf"; Clement Clarke Moore later claimed it, though some credit Henry Livingston.²⁶ Charles W. Jones argued in 1954 that "without Irving there would be no Santa Claus"; Tom A. Jerman replies that Jones relied on a later edition and that Santa descends more directly from German folk gift-bringers and an 1821 New York booklet.²⁴ Either way, Santa borrowed the bishop's name, not his life.

The strongest objections

"There is no good evidence he existed at all"

The earliest account comes at least a century after Nicholas's death, and the introduction to the 2014 English translation of Michael's Life says, "It is unclear, unfortunately, whether St. Nicholas of Myra ever existed."¹¹ But uncertain details are not proof of invention. A cult rooted at Myra, a sixth-century shrine in the capital, and a story full of accurate fourth-century names are what we would expect if a real bishop stood behind them. Cioffari defends a historical core, and even the cautious Catholic Encyclopedia accepts that he was bishop of Myra. The fair verdict is "probably real, poorly documented."

"Patron saints are old gods in new clothes"

Many Protestants object to patron saints as such. John Calvin complained that "individuals adopted particular saints, and put their faith in them, just as if they had been tutelar deities."²⁷ Devotion can drift into superstition. But the earliest Nicholas story answers the charge on its own terms. The generals pray to "the Lord, God of your servant Nicholas," asking God to hear "the intercessions of this holy priest of yours." The saint is a fellow servant who prays, not a rival to God.

"Santa has buried Christmas, so why keep Nicholas?"

Some Christians feel the commercial Santa has crowded out Christ. The Orthodox answer is to recover the real Nicholas, a bishop remembered for confessing Christ's true divinity and giving in secret. The cure for a fictional saint is the historical one, honestly presented.

What we can say confidently

• The Church has always remembered Nicholas as a bishop of Myra in Lycia, and no rival identity is attested.
• The oldest account, the Praxis de stratelatis (460 to 580 by Anrich's dating), shows him rescuing condemned men and reflects real people of Constantine's reign.
• Justinian built a shrine to "St. Priscus and St. Nicholas" in Constantinople.
• Michael the Archimandrite's Life (814 to 842) openly relies on oral tradition, and later Lives merged Nicholas with Nicholas of Sion.
• The slap first appears as a blow to "a certain Arian" in the fourteenth century, and to Arius in the sixteenth.
• His relics were taken from Myra to Bari in 1087.

What remains disputed

• The date of the Praxis (Anrich and Meisen) and of the lost ancient Life that Cioffari believes Eustratios used in 583.
• Whether Nicholas attended Nicaea.
• Whether the dowry story preserves a real act of charity.
• His dates of birth and death.
• Whether the bones in Bari, Venice and elsewhere are his.
• How much Irving, and how much German folk custom, shaped Santa Claus.

Conclusion

The Nicholas of history is quieter than the Nicholas of legend. We cannot prove that he struck Arius, threw gold through a window, or sat at Nicaea. What the oldest witness remembers is a bishop who ran through his city to pull a sword away from innocent necks, told a corrupt governor the truth to his face, and was trusted in prayer by soldiers condemned without a trial. That is enough to make a saint, and it is the Nicholas the Church still praises in its kontakion.

The Orthodox faith does not need inflated evidence. It confesses that Christ has trampled down death, that those who die in Him are alive, and that a bishop who laid down his life for his people may still pray for them. For more, see our Lives of the Saints page and the Church Fathers guide.
