Books of the NT: "Their authors were associates of Jesus or his immediate followers, men to whom Jesus had entrusted the leadership of the early church. The Gospel writers Matthew and John were some of Jesus' closest followers. Mark and Luke were companions of the apostles, having access to the apostles' account of Jesus' life. The other New Testament authors had immediate access to Jesus as well: James and Jude were half-brothers of Jesus who initially did not believe in him. Peter was one of the 12 apostles. Paul started out as a hater of Christianity, but he became an apostle after he had a vision of Christ. He was also in communication with the other apostles." These are not Roman or Greek philosophers. Though some of the bible was written in Greek. "Our modern translations are confirmed by a huge number of ancient manuscripts in both Hebrew and Greek, including the mid-20th century discovery of the Dead Sea Scrolls. These scrolls hold the oldest existing fragments of almost all of the Old Testament books, dating from 150 B.C. The similarity of the Dead Sea manuscripts to hand copies made even 1,000 years later is proof of the care the ancient Hebrew scribes took in copying their scriptures."
