As citizens of the Roman Empire, the Jews of Hispania engaged in a variety of occupations, including agriculture. Until the adoption of Christianity, Jews had close relations with non-Jewish populations and played an active role in the social and economic life of the province. The edicts of the Synod of Elvira, provide evidence of Jews who were integrated enough into the greater community to cause alarm among some. Of the Council's 80 canonic decisions, those that pertain to Jews maintained a separation between the two communities. It seems that by this time the presence of Jews was of greater concern to Christian authorities than the presence of pagans. Canon 16, which prohibited the marriage of Christians with Jews, was worded more strongly than canon 15, which prohibited marriage with pagans. Canon 78 threatens Christians who commit adultery with Jews with ostracism. Canon 48 forbade the blessing of Christian crops by Jews, and canon 50 forbade the sharing of meals by Christians and Jews.
