The bulk of these chapters is invariably understood as a general, or as it were abstract, exposition of Christian virtues, without particular reference to a situation at Rome. We read in Luther, for example, that ‘the apostle is about to teach a Christian ethic’ when he begins chapter 12. Nygren states that none of Romans is aimed at circumstances peculiar to Rome, and that chapters 12–13 contain Paul's ‘central view of the ethical life of the Christian’. Käsemann regards 12–13 as general exhortation, only 14.1–15.3 being directed at problems in Rome. According to E. P. Sanders, nothing in Romans is called forth by the situation of the letter's recipients. ‘It seems best’, he writes, ‘to view Romans as being Paul's reflection on the problem of Jew and Gentile, in the light of the coming encounter in Jerusalem’. There are, however, several difficulties with this view. One is that the chapters do not include areas of Christian ethics with which we know Paul was concerned, such as marriage (1 Cor 7; Col 3.18 ff.), slavery (Col 3.22 ff.; Phlm), slander (1 Cor 6.10), suffering for Christ (2 Cor 1.7), generosity (2 Cor 8.6 ff.), avoiding witchcraft and gluttony (Gal 5.20; Phil 3.19), working hard (1 Thess 4.9–11). If Paul were writing a deliberately general ethic, we should have expected perhaps more system and certainly a greater range of items.6 More importantly, the view leads to fussy, artificial or disjointed divisions of the chapters into a multiplicity of exhortations which fail to grasp the broad sweep of Paul's thought. In particular the precise relevance of 13.1–7 is left obscure.
