Gustaf Aulen’s classic text of systematic theology, The Christian Faith, should be a welcome delight to the Christian theologian. The reputation of this work has steadily increased over the years as a clear and sound guide to the substance of the Christian faith.
Besides treating the whole compass of traditional themes associated with the doctrines of God, Christ, and the church, Aulen has provided new chapters on the communion of saints and on the relation between Scripture and tradition. The chapters on the biblical validation of the content of faith, the doctrine of the Lord's Supper, and the unity of the church and the disunity of the churches provide keen theological insight edifying to all Christians. The statements on the relation between the two testaments, creation and redemption, natural law, the resurrection, the validity of infant baptism, and eschatology address the key issues in debate.
Aulen’s keen analysis and clear presentation of the fundamental motifs of the Christian faith, his sharp demarcation of these motifs from their aberrations in the history of Christian thought and in contemporary theology, and especially his profound sense of the oneness of the church’s faith have endeared this book to students, theologians, clergymen, and hosts of intelligent and inquiring laity of every denomination.
Don’t forget Gustaf Aulen’s classic exposition on the atonement: Christus Victor: An Historical Study of the Three Main Types of the Idea of Atonement.
