Heathen groups assemble for rituals in order to mark rites of passage, seasonal observances, oath takings, rites devoted to a specific deity, and for rites of need. These rites also serve as identity practices which mark the adherents out as Heathens. Strmiska noted that in Iceland, Heathen rituals had been deliberately constructed in an attempt to recreate or pay tribute to the ritual practices of pre-Christian Icelanders, although there was also space in which these rituals could reflect innovation, changing in order to suit the tastes and needs of contemporary practitioners. In addition to meeting for ritual practices, many Heathen kindreds also organize study sessions to meet and discuss Medieval texts pertaining to pre-Christian religion; among U.S. Heathens, it is common to refer to theirs as a "religion with homework".
