This article explores how the internet is being studied and conceived of as a sacramental space. The internet as sacramental space demonstrates how religious users see the internet as a viable place for presenting their beliefs and practices. In order to understand this model, several other dominant conceptions of the internet are offered: information space, a common mental geography, an identity workshop and a social space. Each of these accents a specific use of the internet. The internet as sacramental space is further investigated by considering several typologies of online spiritual communities emerging from a recent online community study. Each typology highlights how the internet as sacramental space encompasses traits of the previously stated models and illustrates how the internet is used as a spiritual tool, religious identity, a space for personal spiritual pursuits and a social spiritual support sphere. A survey of current CMC research on religion is also presented.
