ROME (AP) — Inside a chapel on the edge of Rome, a nun uses a key to open a wooden wall panel, revealing a hidden niche. Behind glass and stitched loosely to supporting backing hangs a relic of holy suffering: the bullet-pocked, bloodstained undershirt that John Paul II was wearing when a gunman shot him in the stomach in St. Peter’s Square.

The short-sleeved garment bears the initials “JP,” sewn in red cotton thread on the label by nuns who did his laundry. Jagged rips run down from the neck and sides, made when emergency room staff tore open John Paul’s shirt as they raced to save the 60-year-old pontiff’s life.
