The Evolution of a UCC Style focuses on the development of themes that define the United Church of Christ (UCC). Walker examines the ethos and culture of the UCC rather than simply describing its structures, and addresses the themes of inclusiveness, diversity of theological heritage (Reformation, Enlightenment, and Pietism), congregational polity (the one and the many), liberal theological approach, and ecumenical spirit. She also takes a look at the tensions and boundaries contained within each theme.
