Luke did not claim to have witnessed what he wrote about Jesus. On the contrary, he said that he undertook “to compile an account of the facts” based on the accounts of “eyewitnesses.” Moreover, he “traced all things from the start with accuracy, to write them to you in logical order.” (Luke 1:1-3) The results of Luke’s labors show that he was a careful researcher. Perhaps he conducted interviews with Elizabeth, with Jesus’ mother, Mary, and with others in order to collect his material. Much of what he wrote is unique among the Gospel accounts.—Luke 1:5-80.
