What is the right way to worship? Right worship does not require a return to the identical forms found in the early church or later in Rome or after that in Westminster. What it calls for is a faithful response today to the God of our salvation in light of those biblically ordered and historically informed patterns. In this study Robbie Castleman uncovers the fundamental shape of worship. What she unearths is a shape that is outlined in Scripture, enacted in Israel, refocused in the New Testament community, regulated and guarded by the Apostolic fathers, and recovered in the Reformation. It is a worship that can and does still shape the liturgy of many congregations today.
