Pope Francis has once again shown his miraculous healing power, the third time he has done it this year.

In September during his pastoral visit to the United States, the Pope kisses a one-year-old baby girl named Gianna after he asked the driver of the popemobile to stop during a motorcade in Philadelphia, CBS Phily reported.

Joey Masciantonio and his wife Kristen were there to see the Pope even for the briefest of moment as the Pope's motorcade passed by. They brought along their daughter Gianna who had a rare inoperable tumour in her brain.

As they stood in front of Independence Hall, the papal motorcade arrived. To their surprise the popemobile stopped.

From a distance, Pope Francis saw Gianna and asked his bodyguard Domenico Giani to fetch the girl.

The bodyguard carried Giana and lifted her up so that the Pope could kiss her. Giani then returned the baby back to her stunned parents.

If the Masciantonio couple were stunned then by their luck to have their ailing baby kissed by the Pope, they were even more shocked when they found out just recently that Giana's brain tumour was already gone!

The recent brain scans on their baby showed the large tumour that was clearly visible two months ago was no longer there, amazing even the doctors at the hospital.

"She's getting better and stronger. She's blowing kisses. She's starting to point at things," a delighted Kristen told Eyewitness News.

"I think this is all from God. I believe the Pope is a messenger from God," her husband Joey chimed in.

The couple said they are positive that Gianna's future is a bright one, and they can't wait to sit down to show her and tell her how she was healed by God through His messenger, Pope Francis.

Also during his U.S. visit last September, the Pope also showed his healing power when he blessed a 12-year-old paralytic girl who was one of those who greeted him at JFK Airport in New York, The Gospel Herald said.

Julia Bruzzese of Brooklyn, New York was in a wheelchair when the smiling Pope stopped by, touched her face and blessed her. She had been using the wheelchair ever since she suffered a sudden paralysis whose cause was a mystery to her doctors.

Her doctors said she seemed to exhibit symptoms of Lyme disease. But the problem was that her blood tests showed she was negative for that disease.

But days after Julia was blessed by the Pope, her doctors finally discovered the cause of her paralysis as her blood tests confirmed that she had Lyme disease, an ailment that can easily be treated with medication.

"[Meeting the pope was] the most precious moment of my life," the young girl said.

In August, the Pope performed his first medical miracle in Rome. He ordered a halt to his motorcade in the rain as it entered St. Peter's Square and asked his aide to bring to him the baby he saw being lifted at the barricade by her parents. The Pope briefly placed his palm on the chest of the three-month-old girl who was suffering from Down's syndrome and had two holes in her heart.

Later when the doctors checked on the baby, they found one of the two holes had completely closed while the other one was reduced to half its former size.

Lynn Cassidy, the mother of the baby, told the Washington Post, that what happened to her child made her believe that "God can act through the pope's blessings in miraculous ways."

Last March, authorities also attested that Pope Francis turned the dried blood of St. Gennaro into liquid in Naples, Italy.
