LOL!
We have first hand witnesses in the Gospels. Mark traveled with Jesus, Matthew was an apostle, Luke, even though he traveled with Paul for awhile, got his information from traveling with Jesus and from the Blessed Virgin Mary and John was an apostle.
Why do you not believe the Gospels since they are first hand accounts of people who traveled with Jesus?
We have to understand, WV, in the RCC, Bible study ends with John and picks up again with James. “Paul? Paul who? You mean the guy that was part shyster and part saint??” is the typical response. They do not seem to realize that AFTER Christ spoke with the 12, He spoke with Paul. And made him the Apostle to the Gentiles. And gave him Romans through Philemon to give to us to build His Church, the Body of Christ. Not important or flashy enough, I guess. Too bad, there is a WORLD of information given by Christ to Paul to us. Only the gospel of the grace of God, given distinctly for the Body of Christ, among other things..Of course, to admit this would blow apart the deceit of Rome. Not to mention all those saints that have recipes named after them..
