1. Multiple similar stories, told without careful labels
* The Gospels describe more than one anointing of Jesus, and they do it in overlapping ways:
* Luke 7: an unnamed “sinful woman” anoints Jesus’ feet with ointment and her tears.
* John 12: Mary of Bethany (sister of Martha and Lazarus) anoints Jesus’ feet with costly perfume and wipes them with her hair.
* Matthew 26 / Mark 14: an unnamed woman anoints Jesus’ head at Bethany shortly before the Passion.
Ancient writers did not treat these as clearly separate events. Because the gestures, perfume, setting, and emotional tone echo one another, many early readers assumed these were different tellings of a single incident, not multiple anointings. Once that assumption is made, identity fusion becomes almost unavoidable.
2. Mary Magdalene enters because she is prominent and nearby
* Mary Magdalene appears immediately after the unnamed “sinful woman” in Luke 8:1–3. Luke introduces her as someone from whom seven demons had been cast out, a vivid but unexplained detail.
Later interpreters drew a dotted line:
* unnamed sinful woman
* forgiven much
* dramatic transformation
Mary Magdalene, just introduced, with a dramatic past. The mind loves economy. Why invent two women when one will do? Luke never says they are the same person, but he places them close enough that later readers felt invited to connect them.
3. John’s Gospel blurs boundaries further
John names Mary of Bethany as the anointer, but he also portrays Mary Magdalene as:
* intensely devoted
* the first witness of the resurrection
* emotionally expressive in her love for Jesus
Later readers noticed that both Marys are defined less by biography than by ardent devotion, and ancient exegesis was far more comfortable with symbolic identities than modern historical analysis. Different Marys, same posture of love, same feet, same perfume, same tears. The lines soften.
4. Gregory the Great seals the deal
In 591 CE, Pope Gregory I preached a homily that explicitly identified:
* the sinful woman of Luke 7
* Mary of Bethany
* Mary Magdalene
as one person.
5. Moral narrative preference
The merged figure produced a powerful moral arc:
* sinner
* penitent
* devoted follower
* first witness of resurrection
That story preached beautifully. Separate women did not generate the same sweep. Medieval theology often favored exemplary lives over textual precision. One radiant conversion story was more useful than three carefully separated biographies.
In sum
Scholars and preachers equated these women because:
* the Gospel narratives resemble one another closely
* some women are unnamed, inviting identification
* Mary Magdalene’s dramatic introduction begged explanation
* influential authorities endorsed the fusion
* a single, emotionally rich figure served theology and preaching better than textual restraint
Modern scholarship largely disentangles them again, but for over a millennium, Mary Magdalene carried the perfume, the tears, the demons, and the resurrection dawn all at once.
