This textbook offers a systematic introduction to eschatology. The first part introduces the historical approaches to eschatology. The second part concerns the reasons for eschatological statements in light of important aspects of the doctrine of God and Christ. The third part is devoted to different concepts of the relationship between eternity and time, space and infinitude as well as the question of what is good, true and beautiful. Using a thematic structure, the multiple different approaches and concepts of modern eschatology are clearly presented, and illuminated by the perspective of the classical teachings on the Last Things; which are ultimately brought together in a synthesis. This is an important contribution to a crucial part of the study of systematic theology.
