First, understand that when Sayers says “Church", she is referring to the Anglican communion, with an occasional nod towards Rome. Here is her basic tenet: that Christian dogma matters. It not only matters, but it is a thundering good story. This may seem obvious, but her point is that the modern (mid-twentieth century) church has, as she puts it, "run away from theology", and that, as a result, many, if not most, nominal Christians have very little idea about what it is that the Church really teaches.

This book is a collection of essays and talks written over a period of time (one very annoying thing about this edition is that it nowhere gives the dates of the essays). Sayers' writes about The Other Six Deadly Sins ("Perhaps the bitterest commentary on the way in which Christian doctrine has been taught in the last few centuries is the fact that to the majority of people the word immorality has come to mean one thing and one thing only."), The Faust Legend and the Idea of the Devil ("It is notorious that one of the great difficulties about writing a book or play about the Devil is to prevent that character from stealing the show"), and the relationship between work and religion.

Readers of Sayers' Lord Peter Wimsey will recognize in these essays many of the concerns that are raised in those mysteries, and will be reminded particularly of the philosophical discussions in Gaudy Night.

One word of warning: this book was very poorly edited, to the point where it at times affects readability. It's too bad.
