Rome ? The first-ever scientific test on what are believed to be the remains of the Apostle Paul “seems to confirm” that they do indeed belong to the Roman Catholic saint, Pope Benedict XVI said Sunday.

It was the second major discovery concerning St. Paul announced by the Vatican in as many days.

On Saturday, the Vatican newspaper L’Osservatore Romano announced the June 19 discovery of a fresco inside another tomb depicting St. Paul, which Vatican officials said represented the oldest known icon of the apostle.

Benedict said archaeologists recently unearthed and opened the white marble sarcophagus located under the Basilica of St. Paul’s Outside the Walls in Rome, which for some 2,000 years has been believed by the faithful to be the tomb of St. Paul.
