A medieval emblem of Christ's self-giving love: the mother pelican wounding her own breast to feed her young with her blood — drawn from legend, read through the cross.

Origin
Of legendary, extra-biblical origin — said plainly. The ancient bestiaries (drawing on the Physiologus) told that the mother pelican, in famine, pierces her own breast to revive her young with her blood. This is folklore, not natural history and not Scripture. The medieval church seized it as an allegory of Christ feeding his people with his own blood, and Thomas Aquinas enshrined it in the hymn Adoro te devote: “Pie pellicane, Jesu Domine” (“Loving pelican, Lord Jesus”).
Biblical references: John 6:53–56 · 1 Peter 1:18–19 · Ephesians 5:25 · Psalm 102:6 (the only biblical pelican — a bird of desolation, not the legend)
Meaning by Tradition
Catholic
A beloved eucharistic emblem: Christ nourishing the Church with his own blood. Sung in Aquinas's Adoro te devote and carved on tabernacles, altar rails, and misericords across medieval Europe.
Orthodox
Not a traditional Eastern symbol; where met, it is understood through the same self-giving love, though the East's eucharistic imagery runs along other lines (the Lamb, the chalice).
Protestant
Appears in heraldry and older church carving (and was a personal emblem of some reformers); valued as an allegory of substitution while frankly acknowledged as legend, not biology or Scripture.
A legend pressed into service
The “pelican in her piety” is honest about being a story. No pelican feeds its young on its own blood; the bestiary said so, and the church knew a vivid allegory when it saw one. The image was never offered as fact but as a picture: love that opens its own veins to give life to its children.
Read through the cross
Whatever the bird does or doesn't do, the referent is John 6 and 1 Peter 1 — Christ who gives his blood for the life of the world. The symbol's force is entirely borrowed from the cross; detached from it, it is merely a strange piece of medieval ornithology. Theologos flags the legend plainly so no reader mistakes folklore for the Gospel.
Pastoral Caution
State the obvious: this is allegory built on a myth, not a fact about pelicans or a teaching of Scripture. Its worth is wholly as a window onto Christ's self-gift — useful so long as the legend is never confused with the Gospel it illustrates.
