A society with no grasp of its history is like a person without a memory. This is particularly true of the history of ideas. This book is an ideal introduction to the thinkers who have shaped Christian history and the culture of much of the world. Writing in a lively, accessible style, Jonathan Hill takes us on an enlightening journey from the first to the twenty first centuries. He shows us the key Christian thinkers through the ages - ranging from Irenaeus, Origen, Augustine and Aquinas through to Luther, Wesley, Kierkegaard and Barth - placing them in their historical context and assessing their contribution to the development of Christianity.
