What if: Gospel OF vs. Gospel of

What if it is the gospel of CHRIST as opposed to the gospel OF Christ?

Gospel OF Christ
Like the work OF Michaelangelo. They are things connected to or get their meaning from the object (Michaelangelo). The object is the nexus, for the constellation of things that surround it. Therefore works of David and Mona Lisa fall into it. In reference to the phrase in question it would constitute the historicity, the teachings, the character traits, all the things ABOUT Christ.

Gospel of CHRIST
Like the work of Mona Lisa. In this case the antecedent (or whatever the term for "work" would be -- trying to be academic here) would be equivalent, synonomous, equal to, exactly the object. The work IS Mona Lisa. They are the same thing.

So the gospel OF Jesus Christ are the things ABOUT Him.
And the gospel of Jesus Christ is Jesus Christ Himself.

Now this example does not mean that they are mutually exclusive. For if the latter is the case, then obviously the former flows from it. From the person flows the accountrement, those things about the person. The question really is then, what is the emphasis? The constellation about or the object that centers?
