who wrote the book of mark in bible
Gospel of Mark The Gospel of Mark is anonymous.[6] Early Christian tradition ascribes it to John Mark, a companion and interpreter of the apostle Peter.[7] Hence its author is often called Mark, even though most modern scholars are doubtful of the Markan tradition and instead regard the author as unknown.[8] It was probably written c. AD 66–70, during Nero's persecution of the Christians in Rome or the Jewish revolt, as suggested by internal references to war in Judea and to persecution.[9] The author used a variety of pre-existing sources, such as conflict stories (Mark 2:1–3:6), apocalyptic discourse (4:1–35), and collections of sayings (although not the Gospel of Thomas and probably not the Q source).[10]
