Jesus Deficit Disorder

I recently finished reading Jesus Manifesto by Leonard Sweet and Frank Viola.  In the introduction, they make the following claim:

[W]e feel a massive disconnect in the church today, and we believe that the major disease of today’s church is JDD: Jesus Deficit Disorder.  The person of Jesus has become increasingly politically incorrect and is being replaced by the language of “justice,” “morality,” “values,” and “leadership principles.”  the world likes Jesus; they just don’t like the church.  But increasingly, the church likes the church, yet it doesn’t like Jesus.  (xvi)

Regardless of what you might think about their theology, what do you think about their assessment of the church; that the church suffers from Jesus Deficit Disorder?  Does this claim have some merit?
