In the first volume of this systematic presentation of Christian doctrine, the question of the truth of speaking about God is pursued into the realm of religions. These religions not only compete in the historical disputes but also in the religious pluralism of the present through their different, often opposing claims to truth. Pannenberg's systematic approach to Christian doctrine is based on a specific understanding of the relationship between theology and philosophy, which permeates the presentation of Christian doctrine. The focus of the third volume is the theme of the Church within the framework of the doctrine of the Spirit as an eschatological gift, aimed at the eschatological completion of salvation. The topics of individual reception of salvation through faith, grace, and justification are incorporated into the discussion of the concept of the Church.
