The Social Gospel?

I was reading an editorial piece in the paper today by a national columnist about the long-standing argument between "Conservative" and "Liberal" Christians over the Social Gospel.  The Social Gospel refers to the notion that social/economic justice must have the priority in the work of the Church.  In America, this divide has coincided with the political divide between Republicans and Democrats.  One side side of the argument: the desire to keep the Gospel message focused on the Spiritual needs of the Lost and the Flock; on the other, the belief that the very nature of the Gospel message requires that it be conjoined with concerns over poverty and rights.
In the end, both extremes of the divide have lost something vital by reacting against their opposite position.  Those who want to put the Gospel in a hermetically sealed box where it won't have any interaction with the culture in which the Church operates risk becoming detached from the real needs of those they are trying to minister to.  The Church does indeed need to prioritize its spiritual mission, but forgetting that God created people with physical needs too is an affront to the poor, the downtrodden, the hopeless.  Jesus spent a great deal of his effort with such as these.
On the other hand, those who devote the bulk of their ministry to social missions are in danger of forgetting that social solutions will never fix spiritual problems.  The problems in our world today are SIN problems; not the kind of thing that can be fixed with a government program or non-profit's initiative.  If the Church fails to ensure that the Gospel of Jesus Christ is at the forefront of its mission, it'll be of no more use than other well-meaning social groups who offer temporary aleviation for a root problem.
So what is the solution?  As is often the case, the Truth lies between these two extremes.  The Church must be both Spiritually AND socially aware.  The Gospel without the Cross and the Resurrection won't SAVE anyone, but the Gospel devoid of care for those in need lacks the Heart of our Savior.
