You thought you were going to get off easy here, but no such luck. There's more to "Luke" than you might think.
The Greek manuscripts that we have today record two options for the title of Luke: a longer title, "The Gospel [or Good News] According to Luke;" and a shorter one, "According to Luke." How about some fun facts to help you think about these titles?
What do these facts add up to? Well, there's a great deal of debate about the whole thing. One compelling option is that the longer title is more ancient than the shorter one. But it is possible that the longer title originated in the early 100s after Luke began to circulate along with at least one of the other gospels—that would have helped distinguish the two, since each of the other three New Testament gospels are likewise titled, "The Gospel According to X" or "According to X". What do you think, Shmoopers?
