Like the ancient Celts did before them, CRs are polytheistic and have many gods and goddesses. They believe in spirits and ancestors, too, and they often honour them with rituals and offerings. Offerings to the spirits might be food, or songs, or poetry. CRs often learn the languages spoken by the Celts, if they do not speak them already. These languages include the Irish language, Scottish Gaelic, the Welsh language and others.
