As Christianity spread throughout Europe and the wider world, it encountered and interacted with a wide array of local pagan religions, each with its own gods, rituals, and symbols.
Instead of attempting to eliminate these belief systems, early Christian leaders often adapted elements of local mythology to ease the transition, a process known as religious syncretism.
This blending is evident in the way Christianity adopted pagan gods, mythical creatures, and holy days, gradually transforming them to fit Christian narratives. By repurposing pre-existing symbols and festivals, Christianity became more palatable and familiar to converts, allowing it to integrate more deeply into diverse cultures.
As a result, figures like the Celtic Brigid and the Slavic Perun are sometimes seen as having echoes in Christian saints or symbols, while many other local deities and heroes either faded or survived mainly in folklore rather than as canonized figures.
Paganism Meets Christianity: An Age of Syncretism
This blending approach is especially visible in the transformation of pagan holidays into Christian celebrations. In its earliest centuries, Christianity often existed alongside, and at times in sharp conflict with, pagan traditions.
Some bishops and missionaries encouraged the adaptation of familiar festivals and symbols to ease conversion, while others condemned or destroyed temples and labelled former gods as demons. The resulting landscape was a mix of suppression, negotiation, and creative re-use of older beliefs.
For instance, some scholars note that the Christian feast of the Assumption of Mary on August 15 falls close to the Roman festival of Diana (Nemoralia) and may reflect an adaptation of existing seasonal devotions, though the exact degree of intentional alignment remains debated.
This syncretic method extended beyond festivals to include the gods themselves. In Roman and Greek territories, the interpretatio Romana (Roman interpretation) identified foreign gods as equivalent to Roman deities, making it easier to introduce Christian saints who shared attributes with these deities.
In this way, later Christian imagery of Saint Peter as the “keeper of heaven’s gates” can be read as echoing older Roman ideas about threshold guardians such as Janus. This is best understood as a symbolic parallel rather than a clearly documented one-to-one replacement.
From Pagan Gods to Christian Saints
As Christianity continued to spread, many pagan deities and mythological figures found new life as Christian saints. This transformation was often deliberate, as missionaries recognized that familiar gods and heroes could foster a smoother transition to Christianity if they were reimagined in a Christian framework.
For example, many scholars see connections between the Irish goddess Brigid, associated with fire, healing, and the hearth, and Saint Brigid of Kildare, one of Ireland’s most beloved saints, whose feast falls on the former pagan festival of Imbolc (1 February). As medievalist Pamela Berger argues, Christian monks “grafted” the goddess’s functions onto the saint, preserving familiar symbolism within a Christian framework (as discussed by Elaine Callinan).
In Norse mythology, the thunder god Thor symbolized protection and strength. In Christian tradition, figures like the archangel Michael and certain warrior saints took on protective, battle-oriented roles, offering converts new heavenly protectors without preserving direct worship of the old gods.
Similarly, in the Slavic regions, the thunder god Perun’s qualities were widely ascribed to Saint Elijah, who took over Perun’s role as a weather and storm divinity in East and South Slavic folklore after Christianisation, a pattern documented in both chronicles and modern scholarship.
Through these adaptations, Christianity repurposed powerful figures from existing mythologies, recasting them as Christian heroes or protectors to build cultural continuity
Transformed Beasts, Gods, and Heroes
Not only were gods and heroes repurposed within Christianity, but many mythical creatures were also adapted into Christian mythology. Beasts like dragons, phoenixes, and griffins, once revered or feared in pagan beliefs, took on new meanings in Christian symbolism.
In the pagan East, dragons were often considered symbols of wisdom or guardianship. However, Christianity redefined dragons as embodiments of evil, symbolizing the chaos and sin vanquished by saints.
One of the most famous examples is the legend of Saint George and the dragon, where George, a Christian saint, defeats a dragon, representing the triumph of Christianity over pagan forces
Another creature, the phoenix, originated in ancient Egyptian and Greek mythologies as a symbol of rebirth. As Christianity integrated this symbol, the phoenix became associated with the concept of resurrection, serving as a metaphor for Christ’s death and return to life.
Similarly, the griffin, a creature with the body of a lion and the head of an eagle, was reimagined as a symbol of Christ’s dual nature, blending human and divine attributes. These transformations illustrate Christianity’s tendency to repurpose familiar pagan symbols, allowing the new religion to incorporate aspects of the old belief systems while aligning them with Christian doctrines
Preserving Paganism Through Saints and Symbols
The transition from paganism to Christianity often involved the preservation of certain sacred elements, which were recontextualized within Christian narratives. Trees, rivers, and animals that were once central to pagan spirituality became symbols of Christian sanctity.
In Celtic regions, sacred trees like the oak retained spiritual significance, sometimes associated with saints or Christian martyrs. For instance, Irish tales often depict hawthorn trees as “fairy trees,” retaining their sacred status within Christianized folklore.
Another figure often discussed in syncretic terms is Saint Nicholas. In parts of Northern Europe, later folk images of Nicholas and Santa Claus as a bearded, sky-traveling winter visitor show some similarities to legends of Odin and the Wild Hunt, though this connection is debated and cannot be treated as a simple direct transformation.
These narratives, steeped in pagan tradition, were modified and integrated into Christian culture, allowing the holiday of Christmas to blend seamlessly with pre-existing winter festivities
As one modern paraphrase of Celtic Christian spirituality might put it: “As the tree roots seek water, so does the heart seek truth, finding the divine in the oak, the river, and the sky.”
This approach also extended to animal symbols. In Celtic and European traditions, stags that had carried sacred associations were reinterpreted in Christian art as symbols of the soul seeking God or of Christ’s guidance.
Lions, long used across cultures as images of royalty and power, became central Christian symbols of strength, courage, and the “Lion of Judah” drawn from biblical texts. By retaining these symbols, Christianity enabled cultural continuity, preserving the spiritual significance of pagan beliefs while encouraging the worship of a single Christian god.

Adapted Legends: Folklore Becomes Canon
Christianity’s integration of pagan mythology extended beyond gods and beasts, incorporating well-loved local legends into its lore. Folktales and cultural myths that once centered on nature spirits, heroes, and local deities were reinterpreted to fit Christian virtues and morals, thus becoming part of the Christian canon.
For instance, the story of the Wild Hunt, a spectral phenomenon where a ghostly procession of hunters rode through the skies, was reshaped in Christian contexts as a harbinger of divine justice. In some regions, the hunt leader was reimagined as Saint Nicholas or other saints, symbolizing the divine judgment cast upon the wicked or a warning to live righteously.
Similarly, the myth figure called Green Man, associated in modern interpretation with nature’s cyclical rebirth, was absorbed into Christian iconography. Foliate heads and Green Man motifs appear on medieval church carvings across Europe, where later authors read them as symbols of death and rebirth, or even as Christianised nature imagery.
The Green Man’s presence on church walls and carvings illustrates how Christianity adopted regional symbols to create connections with familiar beliefs.
Other figures, like the Irish banshee or Scottish wraiths, became cautionary tales in Christian storytelling, often recast as spirits warning of impending death, aligning with Christian teachings on mortality and the afterlife.
In many cases, Christianity allowed local legends to survive by reframing them with Christian morals, creating narratives that resonated with local cultures. These stories, though altered, preserved elements of their original pagan meaning while encouraging Christian virtues, thus fostering a blend of faith and folklore.
Sacred Beasts and Symbolic Figures in Christian Mythology
The transformation of mythical beasts within Christian mythology served as an important bridge between Christianity and pagan beliefs. Symbols like lions, eagles, serpents, and even wolves, creatures once imbued with deep mythological significance, were reinterpreted as representations of Christian ideas.
The lion, for example, an ancient symbol of royalty and power, became associated with Saint Mark and depicted as a guardian of faith. Similarly, the eagle, a symbol of divine strength in various mythologies, was adapted as a Christian symbol of ascension, representing John the Evangelist and the soul’s ascent to heaven.
Another example is the phoenix, a bird that embodies the cycle of life, death, and rebirth in ancient Egyptian and Greek mythology.
In Christianity, the phoenix symbolized the resurrection of Christ, depicting how faith could transform death into eternal life. This adaptation allowed pagans to see their sacred symbols reinterpreted through a Christian lens, creating a natural and familiar resonance with the Christian doctrine.
Dragons, common in European mythology as either wise or dangerous beings, were often depicted as evil in Christianity, representing Satan or the embodiment of sin.
Stories of saints like Saint George and Saint Martha slaying dragons became allegories for Christian triumph over pagan beliefs. These tales of dragon-slaying exemplified the Christian narrative of good conquering evil, aligning Christian teachings with existing mythological themes.
By repurposing these animals and mythical creatures, Christianity created symbols that resonated with local populations, fostering familiarity with the faith.
Christianity’s Evolving Mythology in Modern Culture
As Christianity evolved, it continued to integrate symbols and traditions from pagan beliefs, even into the modern era. Many of today’s Christian holidays, like Christmas and Easter, still carry traces of their pagan roots.
Christmas, celebrated on December 25th, falls close to late Roman festivals such as Sol Invictus and the extended Saturnalia period, and many historians argue that date and imagery interacted with existing “sun rebirth” symbolism, while others stress independent Christian calendrical reasoning.
Symbols like the Yule log, evergreen decorations, and mistletoe likely continue older European winter customs that were later integrated into Christmas, while Easter’s eggs and hares come from medieval springtime and fertility folklore rather than from the New Testament itself.
Modern Christianity also preserves folklore through its festivals, iconography, and even rituals, bridging the past with the present. For instance, the veneration of saints in Catholicism reflects the preservation of ancient godlike figures reimagined within Christian contexts.
Saints like Saint Christopher, a protector of travelers, reflect the function of deities once invoked for safe passage. This ongoing syncretism demonstrates how Christianity continues to draw upon ancient myths, creating a legacy where faith and folklore coexist.
Today, Christian symbols and rituals resonate with the echo of ancient beliefs, proving that religious syncretism remains a vital part of cultural continuity. The continued integration of these symbols serves as a reminder that mythology and faith are interconnected, allowing ancient practices to survive within a modern religious framework.
Conclusion: Mythology’s Timeless Influence on Faith
The enduring presence of pagan symbols, gods, and legends within Christianity reflects a timeless connection between myth and faith. By embracing elements of local beliefs and reshaping them within a Christian framework, early Christian leaders built a faith that was both new and familiar to converts.
Saints replaced gods, festivals honored Christian ideals while respecting cultural customs, and mythical beasts became symbols of Christian virtues.
This integration created a unique mythology within Christianity that honored the old beliefs while introducing a new faith.
For believers, these symbols serve not as mere stories, but as creative languages through which core Christian convictions about God, Christ, and salvation are expressed in culturally familiar forms.
Today, Christianity continues to carry traces of its mythological roots, from symbols like the cross and the fish, to the presence of ancient festivals reborn as Christian holidays.
The legacy of religious syncretism between Christianity and paganism highlights the adaptability of faith in its ability to absorb and repurpose beliefs to bridge communities and cultures. This fusion of myth and religion illustrates the timeless power of storytelling, providing both continuity with the past and a pathway for spiritual growth.
Through the lens of Christian mythology, we see how faith can evolve and thrive by embracing the wisdom, values, and symbols of those who came before.
