A level sociology text books seem to focus on four theorists of postmodernity and religion: Giddens, Bauman, Heelas and Lyon. This post is a bare bones summary of what they say about how religion changes to ‘fit’ postmodernity.
Anthony Giddens: High Modernity and Religion
Zygmunt Bauman: Postmodernity and Religion
David Lyon: Jesus in Disneyland
Paul Heelas: Postmodernity and The New Age Movement
