Hmm? Did Justin Martyr actually quote from any of our four gospels? Can you elaborate on that a bit please?
Not if you believe a site like this...

But the question is:
should you? (hint: THE FORMATTING).
The case against, once again, revolves around obsessing about a set of pseudo data, i.e. things that loom large in the minds of certain people. In this instance, it is things like: Justin Martyr never calls the gospels by name, even though he knows his bible backwards and often names the OT book he is quoting from. Instead (it is alleged) he knows of a single work called "the memoirs of the apostles". Given that this "work" obviously has some sort of resemblance to our extant gospels, some even go so far as to claim that the four gospels were made out of this work, i.e. some time between the time of JM (fl. mid 2nd C.) and Irenaeus, who wrote some twenty years later or so.
Now perhaps all this sounds insurmountable. But there are some other factoids to take into account here, of varying degrees of importance. Note also that this site is typical in not actually analyzing any of the data (ie the gospel-like material in JM).
This can be seen at the admirable Textexcavation site:
http://www.textexcavation.com/justinmartyr.html
The first thing to note is that, as the text stands, JM actually refers to the "gospels"; he also says the "memoirs of the apostles" were written by the "apostles and their followers". So all this implies that he knew of more than one text (indeed, one might think, at least four: plural apostles (this would be Mark Matthew and John) and plural followers (Mark (proxy for Peter) and Luke (proxy for Paul)). However, one does not need to go down this somewhat speculative route, merely note that in the text of JM there is reference to “gospels”.
Scond, if you list all the gospelly-type stuff in JM, it more or less neatly condenses into what is in the synoptics, plus a tiny handful of other traditions and glosses, the most famous of which is that Jesus was born in a cave (seen also in the Protoevangelium of James). Justin is clearly using source(s), and it is noteworthy that the source(s) he is using corresponds closely to what is in our present day gospels, with very little else.
Although Justin uses strikingly Johannine language on occasion, whether he actually alludes to the Johannine literature is endlessly agonized over. Answer: unclear.
Third, when Justin refers to gospelly type stuff, he strings together material that when we compare it to the modern gospels, often seems to combine material from both Luke and Matthew. Mark is harder to call because so little of Mark is not also in Luke and Matthew (even so, JM refers to some such).
Fourth, this characteristic points towards the directionality of the gospels as we know them and JM. Quite simply, the procedure for producing the gospels we have today out of a single proto-gospel would be quite problematic (to say the least).
In particular, his account of the nativity is a stringing together of the material in Matthew and Luke. This material is unique to the respective gospels. Furthermore, the nativity material of Luke, despite being clearly Lucan in style, is nevertheless likely to be part of a “second edition” of Luke – the third chapter opens up with a grand formal opening that may have been the original opening.
We thus have a case of JM quoting from material that was unique to Luke and yet was added to the rest of Luke (presumably by the same author on stylistic grounds) as a prologue.
There are many other arguments of this type revolving around Koester’s requirement for identifying quotations based on them containing author-specific modifications of his/her own sources. Good works on this in the JM case are
Bellinzoni, A. J. The Sayings of Jesus in the Writings of Justin Martyr. Leiden. 1967.
And
Gregory, A. 2003. Reception Of Luke & Acts In The Period Before Irenaeus: Looking Of Luke In The Second Century (Wissenschaftliche Untersuchungen Zum Neuen Testament 2)
Of these, Gregory’s is the more critical – indeed, he has been criticised for a tendency towards hyper-skepticism. But even so, he accepts that JM must have known Luke.
I would recommend getting hold of one or both of these if you are interested in the topic!
JM also seems to quote from Mark, as follows:
And when it says that he changed the name of one of the apostles to Peter, and it is written in his memoirs that this also happened, with the nicknaming of others as well, two brothers, who were the sons of Zebedee, with the name of Boanerges, that is sons of thunder, this was a sign that it was that very same man through whom also the nickname of Jacob was given to be called Israel, and Hoshea was called Joshua by name, through whose name also the people who remained from those who had come out of Egypt went into the land promised to the patriarchs.
(Dialogue 106:3).
This one is particularly interesting. The passage about the Boanerges is only in Mark. And here, JM seems to assign the text to the memoirs of “Peter”. Now, this is not quite certain, because JM only writes, “and it is written in his memoir” – who does this refer to – Jesus, or Peter? But we know that JM consistently talks about the “memoirs of the apostles”, not of “Jesus”. Since at least the time of Papias, it has been held in the church that Mark was in fact the writer up or amenuensis of Peter. In other words, on the face of it, JM here is not only quoting a tradition found only in our modern Mark, he is also explicitly referring it to that work too.
As with all these topics, I would not expect to persuade of this topic here – it involves a lot of detailed comparison of greek, the style of Luke (and Matthew), etc etc. All I can suggest is that you read and think about the topic at some length, and then I hope you will come to see that by far the most reasonable view is that Luke, Matthew and Mark were already extant in the time of JM.
