Death and Resurrection of Jesus - Last scene of The Passion of the Christ

The death and resurrection of Jesus Christ as portrayed in Mel Gibson's The Passion of the Christ with the powerful and beautiful background music of Zack Hemsey's “The Way (Instrumental)“. The video has the bookends of Isaiah's prophecy (Isaiah 53) of the Messiah written around 700 B.C and at the end of the video is the fulfillment of the prophecy in perhaps one of the most important historical documents contained within the New Testament, namely 1 Corinthians written in 56 A.D. 1 Corinthians is one of the 13 (out of the 27) books of the New Testament that was written by Paul the Apostle. New Testament scholars accept the importance of Paul's letters (the scholars that are skeptics agree that Paul is the author of seven of those books i.e. Romans; 1 Corinthians; 2 Corinthians; Galatians; Philippians; 1 Thessalonians; and Philemon). This is important because Paul's credibility in the eyes of skeptical and theist scholars alike is incredibly high. Why is this the case?
