In this paper, I will consider whether the impact of Marcion and his followers’ treatment of the Old Testament is discernible in the Old Testament quotations in Codex Bezae’s Luke. I will pay special attention to indicators of Old Testament awareness in Codex Bezae’s transmission history, taking into account the quotations’ layout in Codex Bezae (e.g. paragraph division), their text (e.g. readings that can be shown to have changed in the transmission of the text of the manuscript) and the context of the quoted text (e.g. introductory formulae of the quotations).
