in which period of time were the gospels written
Gospel The four gospels of the New Testament — Matthew, Mark, Luke and John — are almost our only source of information on Jesus, and thus occupy a uniquely important place in Christianity.[4] They were all written in the period between c. 70 AD and the end of the 1st century, by anonymous authors, and stand at the end of a process of oral and written tradition that began on, or even before, the death of Jesus.
Gospel of Mark The Gospel of Mark was written anonymously.[7] Early Christian tradition ascribes it to John Mark, a companion and interpreter of the apostle Peter.[8] 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.[9] 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.[3] 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]
