The following are a series of questions discussed on BeliefMap which are related to the apostle Paul (formerly Saul of Tarsus).
A lot of it focuses on whether Paul is properly connected to Jesus, especially through Jesus's own apostles. If so, that's a reason to take Paul seriously. We also want to know how well-acquainted Paul was with the historical facts of Jesus, as that impinges on several interesting questions (e.g. how well-acquainted were early Christians in general).
In discussing Jesus's resurrection, we become especially interested in the authenticity and nature of the reported appearance to Paul himself. Several links discuss this.
