How does what happened 2000 years ago in the life, death, resurrection, and ascension of Jesus Christ radically alter the human nature and life situation of men and women in every generation up to the present day? Pursuit of this question provided the initial impetus for this book, a study of two vital themes pertaining to the doctrine of atonement - representation and substitution. The author explores their meaning and role within the theologies of three significantly diverse contemporary theologians - Dorothee Soelle, John Macquarrie, and Karl Barth - concluding with a comparative analysis of all three perspectives in relation to each other.
