CHAPTER 14 Innocent I on Heretics and Schismatics as Shaping Christian Identity

1 Social Identity and Conflict

At the heart of shaping social identity are the boundaries drawn between us and them. Henri Tajfel points to discrimination against out-groups as the means by which in-groups enhance their self-esteem.1 A process of categorisa- tion, identification, and comparison creates and reinforces the boundaries and determines one’s reactions to them by defining an individual’s (and others’) place within or outside a group.2 This collective identity relates not so much the individual to a group, but concerns relations within and between groups.3 Conflict is an inevitable (necessary but not sufficient, according to Marilynn Brewer)4 component of self-esteem, as positive self-esteem comes through forming a superior distinctiveness from other groups. There are, of course, various degrees of conflict ranging from bias to violence. Recent research has argued that bias is not the automatic result of categorisation, nor is hostility in the intergroup context, and that the transition from categorisation to discrimi-

The degree to which differentiation is made distinc- tive determines levels of hostility.5 Social identity theory expresses the idea that a high-status group may be highly discriminatory against a low-status group if they perceive their own superiority as legitimate or under threat.6 John Turner considered the cohe- siveness of in-groups as being based upon a depersonalising willingness to conform and a perception of fewer categorical differences between members of a group but more with other groups.7 When a group develops greater inter- dependence, becomes more highly segmented, or is perceived as threatened, then indifference to an out-group develops into antagonism.8 Whatever its degree, this all may be classified as conflict. Threat is considered an important element in social identity.9 Social psychologists have acknowledged that differ- ences in religious values can be a cause of intergroup discrimination.10 This is certainly true within Christianity. From the New Testament we can tell that from its beginning Christianity grappled with the question of bound- aries. The evangelists, particularly Luke, present Jesus as issuing a universal call to salvation, such that Robert O’Toole can write that membership of a given people can lead to elitism and “[i]t is precisely this elitism that Luke breaks down when he insists that Israel can embrace all humankind.”11 Indeed, a pas- sage like Luke 9:50 (Mark 9:40) that whoever is not against us is for us, would suggest that Christian social identity is to be broad and inclusive and that cat- egorisation is to be avoided. Yet, Luke also used a Q-saying (Matt 12:30; Luke 11:23) that whoever is not with me is against me. Scholars have attempted to
