Religious Talk Online investigated the effects of social media on religious discourse by considering the language use of a small set of religious users and considering what their interaction revealed about the effects of the medium on faith and its presentation. The final chapter brings together the main ideas of the book, arguing that the interaction online has the power to shape the ways in which theology develops. Although many of the ideas presented by the different users in the book are not necessarily new, the ways in which beliefs and faith are argued online has an effect on what issues are focused on. The presence of antagonism in particular and a focus on "debate" has a potential to place emphasis on the way in which something is argued, rather than the validity of particular beliefs.
