Religious similarity serves as a trust cue that excludes atheists

Evidence

In this view, religiously transmitted and enforced prosocial norms may also contribute to distrust of atheists. This could happen because religious similarity is, among other things, a potent cue that another individual shares one’s norms and beliefs, and thus can be trusted. In this view, ethnic outgroups, gays, and atheists may differ in the particular norms to which they are perceived to adhere, and perceptions of atheist norms (or the lack thereof) might lead religious individuals to distrust atheists. — Norenzayan, Ara, Big gods - how religion transformed…, 294
