" When exactly did this all change, and what were the social and theological factors that led to the change? The answer seems to be in the second century and: (1) because of the consolidation of ecclesial power in the hands of monarchial bishops and others; (2) in response to the rise of heretical movements such as the Gnostics; (3) in regard to the social context of the Lord’s Supper, namely, the agape, or thanksgiving, meal, due to the rise to prominence of asceticism in the church; and (4) because the increasingly Gentile majority in the church was to change how second-century Christian thinkers would reflect on the meal. Thus, issues of power and purity and even ethnicity were to change the views of the Lord’s Supper and the way it would be practiced. "
