Arizona State professor Pauline Hope Cheong has an interesting article about the use of Twitter and microblogging and “ambient religious communication:”

What would Jesus tweet? Historically, the quest for sacred connections has relied on the mediation of faith communication via technological implements, from the use of the drum to mediate the Divine, to the use of the mechanical clock by monks as reminders to observe the canonical hours of prayer (Mumford). Today, religious communication practices increasingly implicate Web 2.0, or interactive, user-generated content like blogs (Cheong, Halavis & Kwon), and microblogs like “tweets” of no more than 140 characters sent via Web-based applications like text messaging, instant messaging, e-mail, or on the Web. According to the Pew Internet and American Life Project’s latest report in October 2009, 19% of online adults said that they used a microblogging service to send messages from a computer or mobile device to family and friends who have signed up to receive them (Fox, Zickuhr & Smith). The ascendency of microblogging leads to interesting questions of how new media use alters spatio-temporal dynamics in peoples’ everyday consciousness, including ways in which tweeting facilitates ambient religious interactions.

The notion of ambient strikes a particularly resonant chord for religious communication: many faith traditions advocate the practice of sacred mindfulness, and a consistent piety in light of holy devotion to an omnipresent and omniscient Divine being. This paper examines how faith believers appropriate the emergent microblogging practices to create an encompassing cultural surround to include microblogging rituals which promote regular, heightened prayer awareness. Faith tweets help constitute epiphany and a persistent sense of sacred connected presence, which in turn rouses an identification of a higher moral purpose and solidarity with other local and global believers. Amidst ongoing tensions about microblogging, religious organisations and their leadership have also begun to incorporate Twitter into their communication practices and outreach, to encourage the extension of presence beyond the church walls.
