More than just providing a brief overview of the faith, Weeks ties his explanations of Presbyterianism to actual congregational situations in Presbyterian churches and examines major themes in Reformed life. New chapters and sections address spiritual practices, "hot-button" issues among Presbyterians, changes in hymnody, and respect for God's creation. The adoption of a Presbyterian Brief Statement of Faith, the growth of newer Reformed churches worldwide, their influence on Christian worship and work in the United States, and the growing importance of other world religions also receive Weeks's authoritative attention.
