Which parts of the New Testament were written by Jesus?
None of the New Testament was “written” by Jesus of Nazareth. The New Testament is a “testament” – that is, it is a (putative) first-hand report of Jesus’ life, gathered and remembered by His disciples. When Jesus’ words are quoted directly by those who were there, Bible publishers generally set those words in red type to make them stand out from the surrounding commentary (for example, the Sermon on the Mount). Some scholars claim that the testaments are second- or even third-hand, and that the apostles Matthew, Mark, Luke, and John are not necessarily the ones who wrote the Books of those names, at least not in their present form. It is also important to remember that these books were originally in Greek, Aramaic, and other languages. The King James Version was a translation into English by scholars during the reign of the English King James I (1603-1625). But no-one claims that Jesus actually “wrote” the Bible. He lived it.
