Paul is generally considered one of the most important figures of the Apostolic Age and in the mid-30s to the mid-50s AD he founded several churches in Asia Minor and Europe. He took advantage of his status as both a Jew and a Roman citizen to minister to both Jewish and Roman audiences.
Thirteen of the twenty-seven books in the New Testament have traditionally been attributed to Paul. Seven of the epistles are undisputed by scholars as being authentic, with varying degrees of argument about the remainder. Pauline authorship of the Epistle to the Hebrews is not asserted in the Epistle itself and was already doubted in the 2nd and 3rd centuries. It was almost unquestioningly accepted from the 5th to the 16th centuries that Paul was the author of Hebrews, but that view is now almost universally rejected by scholars. The other six are believed by some scholars to have come from followers writing in his name, using material from Paul's surviving letters and letters written by him that no longer survive. Other scholars argue that the idea of a pseudonymous author for the disputed epistles raises many problems.
The main source for information about Paul's life is the material found in his epistles and in Acts. However, the epistles contain little information about Paul's past. The book of Acts recounts more information but leaves several parts of Paul's life out of its narrative, such as his probable but undocumented execution in Rome. Some scholars believe Acts also contradicts Paul's epistles on multiple accounts, in particular concerning the frequency of Paul's visits to the church in Jerusalem.
