Juan Gutiérrez: Complete Achilles Tendon Tear Heals After Frassati Novena

Extraordinary if it happened as told — but the evidence can't fully confirm it.
The account
An LA seminary student with MRI-confirmed complete Achilles tendon rupture was found fully healed at his orthopedic surgeon follow-up after a novena to Pier Giorgio Frassati.

In 2017, Juan Gutiérrez, a Mexican seminarian studying at the Archdiocese of Los Angeles, tore his Achilles tendon playing basketball. An MRI confirmed a complete rupture. His orthopedic surgeon recommended surgery. Gutiérrez, aware of Pier Giorgio Frassati's reputation, began a novena to him.
Several days into the novena, Gutiérrez was praying in an empty chapel and felt an unusual sensation of heat around his injured foot. When he returned to the orthopedic surgeon for the pre-surgical appointment, the surgeon examined him and then reviewed the imaging: "You must have someone in heaven who likes you." The tendon appeared healed. Gutiérrez resumed sports without restriction.
The Archdiocese of Los Angeles opened a diocesan inquiry. The case was forwarded to Rome, where the Dicastery for the Causes of Saints medical board reviewed the MRI comparisons and clinical record. Pope Francis formally recognized the miracle on November 25, 2024. Frassati was canonized on September 7, 2025, alongside Carlo Acutis, by Pope Leo XIV.
Reviewer Notes
We weigh a claim on two things, kept separate from the story above.
Assessed by Miracles Jar AI
Well-defined testable claim (MRI before and after) in a condition with clear natural history; orthopedic confirmation is a meaningful evidential point.
The verdict. Well-defined testable claim (MRI before and after) in a condition with clear natural history; orthopedic confirmation is a meaningful evidential point.
A full Achilles tendon tear on MRI does not spontaneously regenerate within days — the tendon requires surgical repair or prolonged immobilization (minimum 6 weeks) to heal. The orthopedic surgeon's reported comment ("You must have someone in heaven who likes you") after comparing the pre- and post-prayer imaging is notable. Pope Francis recognized the miracle on November 25, 2024. Against: MRI quality and interpretation vary; partial tears can occasionally be read as complete tears, and "complete tears" can sometimes be overcalled. No public peer review of the imaging.
The scientific crux. A complete Achilles tendon rupture in a healthy young athlete does not self-repair within a novena — roughly nine days. The tendon heals via scar tissue over months, never regenerating structurally within days. If the pre-prayer MRI accurately reflects a complete rupture, the post-prayer MRI showing a normal tendon requires explanation beyond natural history. The qualification is that MRI reading accuracy for complete versus partial tears is not 100%, and no independent radiology review has been published.
Evidence weighed.
- MRI confirmed complete Achilles tendon rupture; follow-up exam and imaging by the orthopedic surgeon showed normal tendon. MRI-documented complete rupture followed by full healing without surgery within days is not consistent with known tendon biology — strong support for authenticity.
- Orthopedic surgeon spontaneously commented that the patient must have "someone in heaven who likes him" upon reviewing the imaging. Independent clinician reaction is evidentially significant, even if anecdotal — moderate support for authenticity.
- Dicastery for the Causes of Saints medical board, theologians, and cardinals/bishops all approved the miracle — moderate support for authenticity.
- MRI over-reading of partial as complete tears occurs; without independent radiological review, imaging interpretation cannot be confirmed. This is the principal scientific caveat and is not resolvable from public sources — moderate natural-direction point.
Evidence ledger — what the verdict rests on
MRI confirmed complete Achilles tendon rupture; follow-up exam and imaging by the orthopedic surgeon showed normal tendon.
MRI-documented complete rupture followed by full healing without surgery within days is not consistent with known tendon biology.
Orthopedic surgeon spontaneously commented that the patient must have 'someone in heaven who likes him' upon reviewing the imaging.
Independent clinician reaction is evidentially significant, even if anecdotal.
Dicastery for the Causes of Saints medical board, theologians, and cardinals/bishops all approved the miracle.
MRI over-reading of partial as complete tears occurs; without independent radiological review, imaging interpretation cannot be confirmed.
This is the principal scientific caveat and is not resolvable from public sources.
What would raise this score: Independent diagnostic confirmation from before the event — imaging, biopsy, a second named clinician — would raise this substantially.
What would lower it: Records showing the original diagnosis was provisional or never independently confirmed would move it down.
How this works
We keep two questions apart on purpose — so a thin record can’t make an impossible thing look proven, and a strong record can’t dress up an ordinary one as a miracle. First: Could nature explain it? (taking the account as true for the moment.) The question is whether nature could produce this at all — assuming, for the moment, the events are true as described. Second: is there real evidence it happened? A claim only stands out when both hold up — and we never call anything certain either way. How ratings work →
The natural explanation
The leading natural account for this case is misdiagnosis & the overstated prognosis. Read what it explains — and where it stops.
