Holy Mackerel is a quiz book about the Christianity that surrounds us; in our people, our places, our music, our books, and our beliefs-past and present. It is a book that illustrates the vastness and endurance of the work of the Church in increasingly secular societies and, consequently, the profound impact that Christianity continues to have in the evolution of Western culture. Its questions and answers reach into every aspect of the work and mission of the church, and how its practice and theology continues to be reflected in the culture of the Western world.
