Hw ought theological ethics to draw ethics to draw upon biblical song? This articles takes as a case study Dallas Willard's use of Psalm 23:1 to authorize a general foundation for theological ethics. It uses methodological tools drawn from Richard hays and Kevin Vanhoozer to evaluate Willard's approach. Hays and Vanhoozer have developed approaches intended to connect nondidactic passages of Scripture to theological ethics, but their primary focus has been on narrative passages. This study tests whether their approaches work for song, an even more challenging kind of non-didactic passage. It finds that Willard's approach is generally sound and produces useful theological insights, thought it also has a few important weak points that could be mproved. This conclusion sheds light on the merits of Willard's case and further demonstrates that the tools Hays and Vanhoozer provide are are helpful for evaluating theological use of no didactic literature.
