Santarem

In the mid-13th century — traditionally dated to 1247, though some sources cite 1266 — a woman in Santarém, Portugal, whose husband had abandoned her, sought the help of a local sorceress. The sorceress told her to steal a consecrated Host from Mass, promising to use it to create a love spell that would bring her husband back.

The woman attended Mass at the Church of St. Stephen and received Communion. Instead of consuming the Host, she removed it from her mouth and concealed it in a cloth veil. As she walked through the streets toward the sorceress's house, blood began to flow from the veil — visibly enough that passersby noticed. Terrified, the woman abandoned her plan and rushed home instead.

She hid the bleeding Host in a wooden chest (or, in some accounts, a trunk of linens). That night, both the woman and her husband were awakened by an intense, unexplained light filling their room. Brilliant rays were emanating from the chest where the Host was hidden. The husband demanded to know what had happened, and the woman confessed everything.

The couple spent the rest of the night in prayer before the bleeding Host. The next morning, neighbors and the parish priest were summoned. The priest carried the Host back to the Church of St. Stephen in solemn procession, accompanied by the faithful.

• Multiple witnesses to the bleeding. The Host began bleeding in public — on the street — as the woman carried it home. Passersby noticed the blood flowing from the veil before the woman herself understood what was happening. This provides independent testimony from witnesses who had no knowledge of the theft.

• Spontaneous confession. The woman was not caught by the Church or accused by others. The supernatural events — the bleeding, then the light — compelled her to confess voluntarily, both to her husband and to the parish priest. This makes a hoax extremely unlikely.

• Three days of continuous bleeding. After being returned to the church, the Host continued to bleed for three full days — observed by the priest, the community, and pilgrims.

• The crystal vial of 1340. Ninety years after the initial miracle, when the beeswax reliquary was opened, the wax had been replaced by a crystal vial containing the Host and blood — a transformation that no one had witnessed or could explain. This secondary miracle reinforced the authenticity of the original event.

• Papal recognition. Multiple Popes granted plenary indulgences to pilgrims who visited the relics — Pius IV, St. Pius V, Pius VI, and Gregory XIV. The granting of indulgences by multiple pontiffs across different centuries reflects sustained institutional confidence in the miracle's authenticity.

• 750+ years of continuous veneration. The relics have been preserved and publicly venerated in the same church (now called the Shrine of the Holy Miracle) for over seven and a half centuries. The church itself has been rebuilt and elevated in status specifically because of the miracle.

• Relics accessible today. The Host and blood remain in an 18th-century Eucharistic throne above the main altar of the Shrine of the Holy Miracle in Santarém, where they can be viewed by pilgrims and visitors.
