There is some evidence to suggest that Saint Paul and Saint John may have met at least once. According to the book of Acts in the New Testament, Paul traveled to Jerusalem to meet with the other apostles, including Peter and James, who were early companions of Jesus. This meeting, which is also mentioned by Paul in his Epistle to the Galatians, is believed to have happened around 49 AD. While the Bible doesn’t explicitly say whether John was present at this meeting, it is likely that they would have been in contact at some point during their ministries.
Saint John: Believed to be the youngest apostle of Jesus, Saint John is estimated to have lived from around 1 AD to 100 AD. He is credited with writing the Gospel of John, the three Johannine epistles (1 John, 2 John, and 3 John), and the Book of Revelation.
* Saint Paul: Born Saul of Tarsus, Saint Paul was a Roman citizen and Pharisee who initially persecuted early Christians. Following his conversion on the road to Damascus, he became a prominent missionary and leader in the spread of Christianity throughout the Roman Empire. He is estimated to have lived from 5 AD to 64 or 65 AD. Though he never met Jesus, he is considered one of the most important figures in early Christianity.
Saint John and Saint Paul did not live at the same time.
* Saint John, the apostle who authored several books of the New Testament, lived in the 1st century AD.
* Saint Paul, who was not one of the original apostles but became a prominent early Christian missionary, also lived in the 1st century AD, but likely not for the entirety of Saint John’s life.
While their lifetimes overlapped somewhat, Saint Paul’s ministry likely began after Saint John’s had already been established.
The Bible itself doesn’t mention any meeting between Saint Paul and Mary, Jesus’s mother. Saint Paul’s conversion to Christianity happened after Jesus’s crucifixion and resurrection, and there’s no record of them ever being in the same place at the same time.
Some later Christian traditions and writings, however, do depict a meeting between them. But these accounts are not considered canonical or part of the official Christian scripture.
