Abstract
In a social survey of the states of New South Wales, Victoria and Tasmania religious variables were shown to be related to the sexual attitudes of the respondents. The explanation given is that religion and sex are alternative forms of commitment: religious believers perceive sexual activity differently from non‐believers, and perhaps need it less for their personality integration. It is suggested that Christianity has set up strict norms regarding sexual activities and attitudes because sex is seen as a possible threat to its major function.
