Ethical Formation in Christian Worship investigates worship and formation in view of Christian anthropology, particularly union with Christ. Traditions which value justification by faith wrestle to some degree with how to describe and encourage ethical formation when salvation and righteousness are presented as gracious and complete. The dialectic of law and gospel has suggested to some that forgiveness and the advocacy of ethical norms contend with each other. By viewing justification and formation in light of Christ's righteousness which is both imputed and imparted, it is more readily seen that forgiveness and ethics complement each other. In justification, God converts a person, by which he grants new character. Traditional Lutheran anthropology says that this regeneration grants a new nature in mystical union with Jesus Christ. By exploring the Finnish Luther School led by Tuomo Mannermaa, Gifford A. Grobien explains how union with Christ imparts righteousness and the corresponding new character to the believer. Furthermore, as means of grace, the Word and sacraments are the means of establishing union with Christ and nurturing new character. Considering Louis-Marie Chauvet's "symbolic order" and Bernd Wannenwetsch's understanding of worship as Christianity's unique "form of life," Grobien argues that worship practices are the foundational and determinative context in which grace is offered and in which the distinctively Christian ethos supports virtues consistent with Christian character. This understanding is also coordinated with Stanley Hauerwas's narrative ethics and the traditional Lutheran practice of ethical instruction by the Ten Commandments.
