While the ritual clearly articulated the cultural ideals of a society through ritual symbolism, the unrestrained festivities of the liminal period served to break down social barriers and to join the group into an undifferentiated unity with "no status, property, insignia, secular clothing, rank, kinship position, nothing to demarcate themselves from their fellows". These periods of symbolic inversion have been studied in a diverse range of rituals such as pilgrimages and Yom Kippur. Beginning with Max Gluckman's concept of "rituals of rebellion", Victor Turner argued that many types of ritual also served as "social dramas" through which structural social tensions could be expressed, and temporarily resolved. Drawing on Van Gennep's model of initiation rites, Turner viewed these social dramas as a dynamic process through which the community renewed itself through the ritual creation of communitas during the "liminal phase". Turner analyzed the ritual events in 4 stages: breach in relations, crisis, redressive actions, and acts of reintegration. Like Gluckman, he argued these rituals maintain social order while facilitating disordered inversions, thereby moving people to a new status, just as in an initiation rite. Clifford Geertz also expanded on the symbolic approach to ritual that began with Victor Turner. Geertz argued that religious symbol systems provided both a "model of" reality (showing how to interpret the world as is) as well as a "model for" reality (clarifying its ideal state). The role of ritual, according to Geertz, is to bring these two aspects – the "model of" and the "model for" – together: "it is in ritual – that is consecrated behaviour – that this conviction that religious conceptions are veridical and that religious directives are sound is somehow generated." Symbolic anthropologists like Geertz analyzed rituals as language-like codes to be interpreted independently as cultural systems. Geertz rejected Functionalist arguments that ritual describes social order, arguing instead that ritual actively shapes that social order and imposes meaning on disordered experience. He also differed from Gluckman and Turner's emphasis on ritual action as a means of resolving social passion, arguing instead that it simply displayed them. Whereas Victor Turner saw in ritual the potential to release people from the binding structures of their lives into a liberating anti-structure or communitas, Maurice Bloch argued that ritual produced conformity. Maurice Bloch argued that ritual communication is unusual in that it uses a special, restricted vocabulary, a small number of permissible illustrations, and a restrictive grammar.
