The primary aim of this thesis "Towards the trinitarian christology: Christological analysis of Klaus Hemmerle's writings in the context of his life and work" is to concern the most important christological themes of Klaus Hemmerle's (1929-1994) philosophical and theological work. At the same time, in the context of author's life and work the debate over the way metaphysics and christology relate to each other will be taken into account. Hemmerle's most known essay "Theses for a Trinitarian Ontology" (Thesen zu einer trinitarischen Ontologie) deals with the problem of new genuinely christian trinitarian ontology. The christological assumptions of this approach will be discussed in our thesis.
