Christus Victor

First published in 1931, Aulén's historical study of the doctrine of the Atonement continues to be essential reading for those studying theology. His survey of the three main Atonement theories 'Ransom Theory' 'Satisfaction' or 'Penal Substitution Theory' and the 'Moral Influence' theory as well as his own unique contribution to the debate means that this book has become an enduring classic.
