Just an additional note. Tertullian in his Against Marcion says the following regarding Gospels:
Never mind if there does occur some variation in the order of their narratives, provided that there be agreement in the essential matter of the faith, in which there is disagreement with Marcion. Marcion, on the other hand, you must know, ascribes no author to his Gospel, as if it could not be allowed him to affix a title to that from which it was no crime (in his eyes) to subvert the very body. And here I might now make a stand, and contend that a work ought not to be recognized, which holds not its head erect, which exhibits no consistency, which gives no promise of credibility from the fullness of its title and the just profession of its author.
Now Marcion's conviction was that the works of Paul and the Gospel had been corrupted and altered by his own church. His version of the Gospel (possibly he had available a form resembling what was named Luke) has no name attached. It seems likely he regarded the names as part of the corruption.
Tertullian's argument is strange, he accuses Marcion (perhaps rightly so) of starting with a copy of Luke then faults him for not giving his redacted version a pseudonymous name. Going so far as to say anonymous Gospels "should 'not be recognized'. He clearly illustrates why names were assigned to anonymous Gospels; it supplied "credibility".
