Systematic theology is somewhat like the philosophy of theology: this discipline reflects on the meaning and current relevance of the Christian faith. This also includes references to non-Christian or even non-religious reflection on reality and society (in addition to philosophy, for example, in sociology or migration studies). At the Oldenburg Institute of Protestant Theology and Religious Education, this is done primarily from the perspective of the academic training of future religious education teachers, who will be something like moderators of Christian religion in their professional activity, but also contact persons for questions in society beyond the school context. To this end, it is important to perceive theology in an ecumenical context, i.e. to consider denominational plurality on the one hand and to explore the intercultural references that constitute Christianity in its worldwide contextuality on the other. Last but not least, systematic theology also reflects the Christian perspective on reality with regard to the diversity of religions.
