My friend Larry Hurtado has had a running debate about whether Justin Martyr used the word Gospel to refer to a particular book with a named author or not. Here is the gist of his argument, which I agree with. See what you think— BW3
“The first thing to note is (as I noted in my posting) that Justin does refer to what he calls “memoirs” as “those which are said to be [ἄ φημι] written by the apostles and those who followed them” (Dialogue 103.8). That Justin does not name the figures in question is likely because this text purports to show him in dialogue/debate with Jewish figures over the validity of Christian faith. His interlocutors wouldn’t be impressed were Justin to name-drop! So, instead, Justin simply indicates the nature and status of those individuals to whom he (and the tradition on which he depends, alluded to in the ἄ φημι phrasing) ascribed these “memoirs.” So, that Justin doesn’t name who these figures were is hardly evidence that he didn’t have names to hand for them. This is rather a key text in Justin that I think works against the notion of Nongri and Larsen that the identities of the authors of these memoirs weren’t important for Justin.
“Now, second, I suspect that part of the confusion in the present discussion is over the use of the term “gospel” for these works. We all agree, I think, that in Justin’s day the term “gospel” (Greek: εὐαγγέλιον) still carried its originating sense in Christian circles: the message about Jesus, and traditions about him. But, as I noted in my earlier posting, Justin also refers to the “memoirs of the apostles” as “gospels” (ἅ καλεῖται εὐαγγέλια, 1 Apology 66.3). So, it appears that, already by Justin’s time, the term “gospel” had acquired an additional usage as a label for those writings that conveyed Jesus-tradition. That is, “gospel” had acquired the sense of a particular kind of literary text.
“And in Dialogue 100.1 Justin refers to wording as “written in the gospel,” quoting then a saying for which we have parallels in Matthew 11:27 and Luke 10:22. Whether by “in the gospel” he refers to a text of Matthew or Luke is difficult to judge, for the form of the saying doesn’t conform exactly to the preferred text of either passage, e.g., in the Nestle-Aland edition. But the point here is that Justin cites a text, a written gospel.
“So, granted, we shouldn’t presume more than the evidence warrants. But neither should we ignore what evidence we have in favor of the romantic notion that in Justin’s time what we know as the Gospels ascribed to Matthew, etc. were a collection of anonymous writings, or that all was in a state of somewhat amorphous fluidity. Justin doesn’t simply refer to “memoirs of the apostles” collectively, he refers specifically to “gospels” and ascribes them to “apostles and those who followed them,” which suggests to me that Justin had particular figures in mind.
“Larsen’s claim (which Nongbri subscribes to), that “early readers and users of gospel texts regarded the gospel not as a book, but as a fluid constellation of texts,” seems to me to over-simplify and pose as false alternatives the ways in which the term “gospel” was used, and the way in which the gospel texts were viewed in relationship to the gospel message and tradition. I judge that early readers (e.g., Justin) regarded “the gospel” as a message/tradition that took written form in “gospels,” texts which both had individual identities and also formed a collective witness to “the gospel”.
