The Answer to Practical Problems Must Involve Robust Doctrine

Amen to this quote from Donald Macleod's The Humiliated and Exalted Lord, cited by Ligon Duncan:

:Theology exists in order to be applied to the day-to-day problems of the Christian church. Every doctrine has its application. All scripture is profitable and all the doctrine is profitable. Similarly all the application must be based on doctrine. In both the Philippians example-passage and the Corinthian example-passage, Paul is dealing with what are surely comparative trivia, the problem of vain glory in a Christian congregation and the problem of failure of Christian liberality. As a Pastor one meets with these difficulties daily. They are standing problems. Yet Paul, as he wrestles with both of them, has recourse to the most massive theology. It’s not only that you have the emphasis on the unity between theology and practice but you have the emphasis on the applicability of the profoundest theology to the most mundane and most common-place problems. Who would ever imagine that the response to the glory of the incarnation might be to give to the collection for the poor? Who might imagine that the application of the glories of New Testament Christology might be to stop our quarreling and our divisiveness in the Christian ekklesia? That is what Paul is doing here. He is telling them: You have these practical problems; the answer is theological; remember your theology and place your behavior in the light of that theology. Place your little problems in the light of the most massive theology. We ourselves in our Christian callings are to be conscious of this. We must never leave our doctrine hanging in the air, nor hesitate to enforce the most elementary Christian obligations with the most sublime doctrines.
