In his large-scale work "Fundamentals of Dogmatics" the Reformed theologian Otto Weber offers a detailed discussion of what Christian dogmatics is and what it has to achieve. The "questionability and necessity of Christian teaching" is developed as a revelation, as "God's self-disclosure to us, which takes place as a personal encounter and address in the form of the word. The word that has happened is God himself in his self-disclosure, more precisely the Father who opens himself up in the incarnate Son through the power of the Spirit, i.e. the Trinitarian God. "(J. Rohls) The work is characterized by a broad acceptance of theological tradition and the conscious reference to the theology of Karl Barth. The history of dogmatics from the old church to the present is unfolded. The entire presentation takes place with constant reference to the theological and philosophical traditions, to the reformers, the confessional writings, but also to Roman Catholic theology. Creation, doctrine of God, christology, pneumatology, doctrine of the Trinity, anthropology, predestination, ecclesiology and eschatology are central themes of this work. A detailed structure and extensive index make the book an indispensable tool for exploring the subject.
