Marcion of Sinope
The Book of Acts contains an account of Paul's travels and deeds, his conflicts with Greeks and Jews during the Julio-Claudian dynasty, and his interactions with the original Apostles of Jesus. The value of the historical information in "Acts", however, is challenged by some scholars. They believe that it was written from a perspective of reconciliation between Pauline Christianity and its opponents, so portrays Paul as a Law-abiding Jew and omits his dispute with Peter, only briefly mentioning the split with Barnabas. Irenaeus in the 2nd century was the first of record to quote "Acts", and he used it against Marcion of Sinope, who rejected the Hebrew Bible entirely (see also Marcionism).
