From Albert M. Wolters' Creation Regained, pp. 34-35.

We must continue to try to discern, through empirical study and historical experience, what God's specific norms are for areas of human life that the Scriptures do not explicitly address--industrial relations, for example, or the mass media, or literary criticism.

To say this is not to downgrade the authority of Scripture. The recorded explanations are indispensable, not least as an invaluable corrective for those who have their own interpretations of the blueprint. In all disputes of interpretation, the architect's own explanation are  clearly the final authority. The point is that the explanations cannot be fully understood without the blueprint to which they refer, just as the blueprint is in turn largely unintelligible without the explanations. But it is inconceivable that the blueprint should ever be invoked against the architect's own verbal explanations of it. That would be insufferable arrogance on the part of the builder. 

 . . . In Christ we are journeyman builders--still bound to the architect's explicit directions, but with considerable freedom of implementation as new situations arise.
