“Reformed Christians,” write D. G. Hart and John R. Muether, “are increasingly divided over how they ought to worship their God,” a situation they regard as urgent. Drawing on Scripture and Reformed confessions and catechisms, the authors answer such questions as these:
When are we to worship?
How does the regulative principle guide our worship?
How does the dialogical principle shape our worship?
How do we worship with reverence and joy?
What is the place of the means of grace?
How do the elements of worship differ from its circumstances?

Finally the authors tackle “the most divisive issue”-music.
