For some 2,000 years, Catholics have believed a white marble sarcophagus under the Basilica of St. Paul's Outside the Walls was the tomb of St. Paul. Seven years ago, archaeologists removed bits of bones for carbon dating.
Based on the result of carbon dating, the fragments of bones from the tomb did indeed date from the first or second century. The Pope has announced: 'This seems to confirm the unanimous and uncontested tradition that the bone fragments are the mortal remains of the Apostle Paul.'
The result means that they are very likely to be the bones of Paul. However, without DNA test, we cannot be 100% sure.
