At the institutional or individual level one can speak of religion as divorced from, separated from, or married to morality. In this paper, I examine this religion-morality link, at the individual level, in friendly or cooperative behavior in day-to-day American life. Using frequency of prayer to indicate the extent to which religious beliefs and symbols are internalized, and data from a 1974 representative national sample, findings indicate that people who are more religious do seem more friendly and cooperative than less religious ones.
