Do This in Remembrance of Me

Introduction
The existence and nature of the textual problem under examination is identified: although the vast majority of extant Greek manuscripts include Luke 22:19b-20, a small number of manuscripts (principally Codex Bezae) break off the narrative at the words "This is my body" omitting altogether the words over the cup and the Dominical command to perpetual remembrance. This produces two streams of text represented by the manuscript tradition - the "Longer Text" including Luke 22:19b-20 and the "Shorter Text" which omits this verse and a half.
PART ONE Chapter One: The Textual Problem A brief overview is conducted, explaining the nature and significance of the textual problem represented by Codex Bezae at the point of the Last Supper narrative in Luke.
Chapter Two: A Western Non-Interpolation? Examining the possibility that the textual problem under examination is an incidence of the "Western Non-Interpolations" as proposed by Westcott and Hort. Chapter Three: The Codex Bezae (D, 05) A review of the Codex itself, its physical characteristics, together with its history and provenance, leading to the conclusion that the Codex was produced in a bi-lingual (Greek / Latin) community of the second century of the Common Era, in the region of Lyons.
PART TWO
Chapter Four: The Non-Lukan Origins of the Disputed Words A detailed source-critical exegesis of the disputed words of Luke 22:19b-20, focusing on their lexicology and grammar. Examines the argument that the "Shorter Text" is genuine, and that the "Longer Text" is to be explained as an interpolation into the manuscript tradition, intended to harmonise Luke with the institution narratives preserved by Matthew / Mark and by Paul (1 Cor 11:23-26).
Chapter Five: The Non-Lukan Theology of the Disputed Words An examination of the alleged non-Lukan theology reflected by the disputed words. Focuses on the argument that the "Shorter Text" is genuine, and that the "Longer Text" is to be identified and understood as an interpolation into the manuscript tradition that is essentially inconsistent with the theology of Luke.
Chapter Six: Passover, History, and Liturgy in the Disputed Words A survey of the narrative source in which the disputed words have been transmitted, focusing in particular on the possibility that the Passover context has led to a misunderstanding about the number of the cups involved. Chapter Seven: Erroneous Scribal Emendation Considers the possibility that the textual difficulty is the result of either an intentional or unintentional scribal emendation.
Chapter Eight: The Disciplina Arcani. An exhaustive overview of the notion of disciplina arcani as it may have affected early Christianity is conducted, with special reference to the theory as it is articulated by Joachim Jeremias (in his Eucharistic Words) to sustain the authenticity of the "Shorter Text" on esoteric grounds.
PART THREE
Chapter Nine: The Text as Window. A preliminary discussion of the manner in which individual manuscripts may function as windows into the social world of the early Christian community, providing an insight into the world of the scribes who produced them and the communities for whom they were produced.
Chapter Ten: "Thyestean Banquets and Oedipodean Intercourse". The manner and nature of the accusations leveled against the Christian community in the period 100-200 CE are discussed, with particular reference to those which have relevance to the meal practices of the Christian community, and which may then have influenced the omission of Luke 22:19b-20 form Codex Bezae.
Chapter Eleven: Why Codex Bezae was Altered: A Sociological Explanation. The concluding chapter argues that the persecution of the Christian community in Lyons (ca. 177 CE) provides a plausible Sitz im Leben in which the exemplar of Codex Bezae may have been altered, so as to prevent any further accusations of "Thyestean banquets" and to reduce the possibility of further outbreaks of violence and of social ostracisation against the Christian community. Conclusion The results of this study posit a sociologically motivated explanation for a longstanding textual difficulty, in the particular instance of the Western Text recension (principally Codex Bezae) of St. Luke's Gospel. The "Longer Reading" inclusive of the dominical command to a perpetual remembrance of the Lord's Supper is accepted as genuine, and its authenticity is further affirmed by explaining and accounting for the origin and existence of the enigmatic "Shorter Text".
