Although early Christian vegetarianism appears to have been downplayed in favor of more "modern" Christian culture, the practice of vegetarianism appears to have been very widespread in early Christianity, both in the leadership and among the laity. Origen's work "Contra Celsum" quotes Celsus commenting vegetarian practices among Christians he had contact with. Although not vegetarian himself and vehemently against the idea that Christians must be vegetarians, Augustine nevertheless wrote that those Christians who "abstain both from flesh and from wine" are "without number".
