SAN GIOVANNI ROTONDO, Italy - The body of a revered Italian monk known as Padre Pio has gone on public display in the southern town of San Giovanni Rotondo.

Thousands of faithful gathered in the town Thursday to pray and pay their respects to the mystic monk who died in 1968 at the age of 81.

Many Catholics believe Padre Pio, who was made a saint in 2002, bore "stigmata,'' or wounds on his hands and feet like those Jesus suffered at his Crucifixion.

Jose Cardinal Saraiva Martins, head of the Vatican's sainthood office, lead an open-air mass for thousands of faithful before the unveiling of the saint's body.

Saraiva Martins and other church officials later descended into the church's crypt for a private viewing of the body.

State-run broadcaster RAI showed the body in a casket enclosed in crystal, wearing a monk's hooded dark robe.

The officials gathered solemnly around the crypt, and prayed. The faithful, who were being allowed to file past the body later Thursday, followed the ceremony through large TV screens outside.

"Today, we venerate his body, opening a particularly intense period of pilgrimage,'' Saraiva Martins said. "This body is here, but Padre Pio is not only a corpse. Looking at his remains we remember all the good that he has made.''

The Capuchin monk, whose original name was Francesco Forgione, had an enormous following in Italy and abroad. He lived for decades with inexplicable bleeding wounds on his hands and feet.

Church officials exhumed the body so the faithful could pray before it, since this year marks the 40th anniversary of his death. They also wanted to take measures to ensure it was being well preserved.

Since the unearthing in March, the body has been prepared for public viewing in the crypt of the Santa Maria delle Grazie church in San Giovanni Rotondo, a town near the Adriatic in southern Puglia  where the saint lived.

Church officials have said there was no sign of the stigmata on his limbs after an initial examination, and that the body was in good condition.

Organizers said they expect 15,000 people to pay their respects to Padre Pio on the first day of the viewing. It is not yet known when the body will be reburied.

Padre Pio had a huge public following in life, as in death, and his beatification and canonization ceremonies drew hundreds of thousands of people to the Vatican.

For decades, though, many in the Vatican were uneasy about his popularity and scorned him, doubting that his wounds were real or that mystical virtues attributed to him were authentic. He was barred for years from saying mass in public, even as his following grew immensely.
