According to Karl Barth, the obedience of the eternal Son in the economy of salvation is the proper mode whereby he enacts the undivided work of the Trinity ‘for us and our salvation’. This thesis now enjoys rather wide acceptance among contemporary theologians. In many instances, adopting this viewpoint has resulted in significant revisions of traditional trinitarian metaphysics. The purpose of the present article is to demonstrate that adopting Barth's thesis does not require such revision and that this thesis can and should be appropriated within the orbit of traditional trinitarian theology. We will endeavor to establish our claim by considering the relationship between the Son's eternal generation and his economic obedience, and by addressing three major objections that might be raised against our claim.
