Book excerpt: Worship is central to the Christian life. But how should the church order its worship to honor God and enrich his people? Gore assesses the strengths and weaknesses of the Puritan regulative principle of worship in light of biblical teaching, the Westminster Standards and Directory, and Calvin's view, with special attention to adiaphora. Gore submits this work, the product of twenty years of research, reflection, worship, and dialogue, ...not as the final word on the regulation of worship, but as a modest attempt to further the discussion. An excellent work....will both stimulate thought and help resolve some current controversies over worship. There is a good balance of appreciation and criticism of the Puritan heritage....A formulation that needs to be considered in our circles. --William S. Barker
