Book excerpt: This text poses the question "what is theology?" and goes on to discuss issues of methodology, the relation of theology to other disciplines and different theological perspectives. It also investigates topics in the fields of philosophical theology (human existence; revelation; the language of theology; and Christianity and other religions), symbolic theology (triune God; doctrines of creation; the problem of evil and suffering; the person of Jesus Christ; and eschatology) and applied theology (the Church; ministry and mission; word and the sacraments; worship and prayer; and ethics).
