Text in German / This thesis deals primarily with the questions: Is Israel constantly chosen by God or have the devine promises gone over to the chuch? Are jews to be saved without the sacrifice of Christ? Should jews be missionised as gentiles alike? To give responses, the followings steps are worked out: At first an overview on the israelological models that have been opined during church- history is presented. Secondly church-documents are analyzed in spite of their missiological content. Thirdly an exegesis of Romans 9-11 is offered. Following this, those of the church-documents, whose israelology is closest to the witness of scripture, are presented. Finally a conclusion is offered, which states, that jews are constantly chosen, but not to be saved in another manner as gentiles. Therefore the church is continually obliged to bear the Gospel also to Israel. Jews and gentiles alike are to be saved by nothing but the blood of Jesus. / Christian Spirituality, Church History and Missiology / M. Th. (Missiology)

Text in German, summaries in English and German / Die vorliegende Arbeit untersucht, wie die paulinische Ethik von der Eschatologie bestimmtwird. Ausgehend von einer Untersuchung der hellenistisch-römischen Jenseitserwartung und ihren (möglichen) ethischen Implikationen werden der 1. Thessalonicherbrief, der1. Korintherbrief und der Römerbrief hinsichtlichdesVerhältnisses von Ethik und Eschatologie analysiert. Durch Bestimmung und Zuordnung eschatologischer Einzelmotive zu ethischen Weisungen wird die These erhoben, dass eschatologische Motive primär der Begründung exklusivethischer Mahnungen dienen, wenngleich sie auch bei inklusiv-ethischen Themen zum Einsatz kommen.Zugleich zeichnet sich ab, dass das (von Paulus charakterisierte)ethisch-moralische Versagen und die Hoffnungslosigkeit der Heiden sowie die Hoffnung und der ethische Anspruch an Christen in Korrelation zueinander stehen. / This thesis examines how Paul’s ethical teaching is determined by his eschatology. Based on a survey of Hellenistic-Roman expectations regarding the hereafter and their potential ethical implications, this study examines 1 Thessalonians, 1 Corinthians and Romans in order to understand the relation between ethics and eschatology. By identifying and matching individual eschatological motifs with ethical directives the thesis proposed that eschatological motifs are primarily utilized as the foundation for exclusive ethical exhortations, although they also appear in the context of inclusive ethical issues. At the same time, it becomes clear that the moral-ethical depravity and hopelessness of the Gentiles (as they are characterised by Paul) as well as hope and the ethical demands on Christians on stand in correlation with each other / New Testament / D. Th. (New Testament)
