Barth's doctrine of reconciliation is exposited in a characteristic Barthian triad of confession: Jesus Christ is very God, very Man, and God-Man. This third part volume treats the third theme in the three-fold confession, centering on Christ as the God-Man who serves as the Mediator and Guarantor of reconciliation, which is his prophetic office. Due to the size of the third part-volume, it has been divided into two halves. This second half delves into Barth's doctrine of calling or vocation, which stands as the outworking of the doctrine of reconciliation. Barth then turns again to the Holy Spirit, noting the Spirit's role in the sending of the Christian community. The volume ends with a discussion of the Holy Spirit and Christian hope.
