Chris Keith, Le Donne, and others argue for a "social memory" approach, which argues that memories are shaped by socially determined interpretative frameworks, which are shaped by the needs of the present. Any Gospel unit is shaped and interpreted by the ones who remember; the distinction between "authentic" and "inauthentic" is therefore useless. Instead of searching for a historical Jesus, scholarship should investigate how the memories of Jesus were shaped, and how they were reshaped "with the aim of cohesion and the self-understanding (identity) of groups."
