The Book of Luke

That the Gospels are the writings of their traditional Apostolic authors was long held to be settled truth. It was also long held that Matthew was first and as early as the 40sAD, followed by Mark and Luke, and lastly by John, and that all were written before about 70AD. These views have been doubted or denied by New Testament scholars from about the end of the 18thCentury. The dominant view is that the Gospels were not written by eyewitnesses, though they depend on material that may go back to eyewitnesses. Mark is said to have been written first and not much before 70AD. Matthew and Luke are later and depend on Mark and some unknown sources. John is last, follows an independent tradition, and could be as late as 100AD.
