Dieter T. Roth offers a new, critical reconstruction of Marcions Gospel including various levels of certainty for readings in this Gospel text. An extensive history of research, overview of both attested and unattested verses in the various sources, and methodological considerations related, in particular, to understanding the citation customs of the sources set the stage for a comprehensive analysis of all relevant data concerning Marcions Gospel. On the basis of this new reconstruction significant issues in the study of early Christianity, including the relationship between Marcions Gospel and Luke and the place of Marcion in the history of the canon and the formation of the fourfold Gospel, can be considered anew.
