of the times, some of those animals are indeed more likely to cause food poisoning or transmit diseases to people who consume them. British anthropologist Mary Douglas proposed that the "unclean" label had philosophical grounds, namely it was cast on foods that did not seem to fall neatly into any symbolic category. The pig, for example, was seen as an "ambiguous" creature, because it has cloven hooves like cattle, but does not chew cud. Christianity In the very early days of Christianity it was debated if converts ought to follow Jewish customs (including circumcision and dietary laws) or not. According to the account of the Council of Jerusalem in , a compromise was reached between those who wanted full compliance and those who favored a more liberal view. It was agreed that the converted gentiles would have to bear "no greater burden than these necessary things: that ye abstain from meats offered to idols, and from blood, and from things strangled, and from fornication". While the majority of Christians agree that the dietary restrictions of the Old Testament were lifted with Christ's New Covenant, a view known as supersessionism, there are Torah-submissive Christians who believe that they should still be observed. Some, like the Seventh Day Adventists, argue that the liberal view would imply the acceptance even of alcohol, tobacco, rats and roaches as "clean food"; and that God never declares something an abomination and then changes his mind. Supporters of the stricter view have also disputed the interpretation of Peter's vision , claiming that God was merely instructing him not to refer to gentiles as "unclean" since salvation had been extended to them. This is expressly stated by Peter later in the chapter at Acts 10:28 ("but God hath shewed me that I should not call any man common or unclean.") In Acts 10:14 Peter makes a distinction between "common" (Greek κοινόν) and "unclean" (Greek ακάθαρτον) to which God replies in the next verse "What God hath cleansed, that call not thou common [κοίνου]". One modern example of a Torah-submissive group is the Seventh-day Adventist Church, whose co-founder Ellen G. White was a proponent of vegetarianism. Many Seventh-day Adventists avoid meat for health reasons, although vegetarianism is not a requirement. Members of the United Church of God as well as other Sabbath-keeping Christian Churches also believe in abstaining from unclean meats. Seventh-day Adventist Adventists are known for presenting a
