While much research on churches and the LGBTQ+ communities has been done in North America, little research has focused on this topic in Europe. Since 71% of European LGBTQ+ respondents agreed that better acceptance by religious leaders would allow them to live more comfortably as LGBTQ+ people, we investigated the types of messages and imagery that help and hinder Swiss LGBTQ+ Christians’ feelings of acceptance within churches. We also investigated the impact this content had on the feelings of acceptance of Swiss straight Christians. We found that when LGBTQ+ Christians were presented with affirming church messages and imagery, they felt significantly more accepted. Conversely, LGBTQ+ Christians who were presented with non-affirming church messages and imagery felt significantly less accepted. Straight Christians did not evidence significantly more or less feelings of acceptance in either condition, demonstrating affirming church messages and imagery serve as identity safety cues that help LGBTQ+ Christians the most without excluding straight Christians. In a context like Switzerland, where certain churches can be public institutions, institutional churches should consider the impact their messages and imagery have on LGBTQ+ Christians, and the broader LGBTQ+ communities, to cultivate a space of belonging for all.
