Public Worship 101 is an introduction to the Biblical theology of worship, the elements of worship, exclusive Psalmody, and a cappella Psalmody. This book retails for $40.00. It follows the basic outline of Dr. Prutow's Ministry of Worship classes with much more detail, including the addition of important historical data. The purpose of the book is to demonstrate that, in Biblical worship, God renews His covenant with His people as they draw near to Him in the place He prescribes (the gathered congregation), on the day He prescribes, in the manner He prescribes, with the elements He prescribes, including the praise He prescribes both in content, exclusive Psalmody, and manner, a cappella Psalmody, using an order properly deduced from Scripture. Whether this purpose is accomplished is for you, the reader, to judge.
