From reviews of Christian Theology:
An Introduction 2nd edition:

"This book is an extraordinary achievement, a tour de force which will introduce thousands of students to theology as a discipline with a rich heritage, a clear sense of its own methods and norms, and an elusive yet articulate understanding of Christian language."

Praise for previous works by Alister McGrath:

"Perhaps for the first time an expansive and ecumenical survey of Christian Theology has been produced that can be read with the same ease as a serious but gripping novel... "
G.W.P. McFarlane, London Bible College, of Historical Theology

"Alister McGrath... is one of the best scholars and teachers of the Reformation.... [this book] is more than one dared ask for.... How teachers will rejoice in this wonderfully useful book."
