Many religions emphasize the importance of sexual morality. This article argues mating strategies are central to understanding religion. I highlight the reproductive-religiosity model, which suggests that religious behavior is partly motivated by preferences for restricted mating strategies. I then discuss how religion can lead to reproductive benefits. Specifically, religions can make parenting a relatively safer strategy by increasing paternal certainty, which drives men toward parental investment, and alloparenting, which reduces offspring mortality rates. Next, I discuss the social implications of reproductive-religiosity, including mate selection and trust. Finally, I discuss the potential role of mating strategies in the evolution and cultural evolution of religion and discuss future directions for developing an approach to religion rooted in mating interests.
