Christian dietary laws vary between denominations. The general dietary restrictions specified for Christians in the New Testament are to "abstain from food sacrificed to idols, from blood, from meat of strangled animals". Some Christian denominations forbid certain foods during periods of fasting, which in some denominations may cover half the year and may exclude meat, fish, dairy products, and olive oil. Christians in the Catholic, Lutheran, Anglican, and Orthodox denominations traditionally observe Friday as a meat-free day (in mourning of the crucifixion of Jesus); many also fast and abstain from meat on Wednesday (in memory of the betrayal of Jesus). There are various fasting periods, notably the liturgical season of Lent. A number of Christian denominations disallow alcohol consumption, but all Christian churches condemn drunkenness. In the New Testament The only dietary restrictions specified for Christians in the New Testament are to "abstain from food sacrificed to idols, from blood, from meat of strangled animals" (), teachings that the early Church Fathers, such as Clement of Alexandria and Origen, preached for believers to follow. Paul the Apostle recommended that Christians abstain from consuming food that had been offered to idols as it could cause "my brother to stumble" in his faith with God (cf. ). Early Christianity The Council of Jerusalem instructed gentile Christians not to consume blood, food offered to idols, or the meat of strangled animals, since "the Law of Moses has been preached in every city from the earliest times and is read in the synagogues on every Sabbath." In Judaism, Jews are forbidden from consuming (amongst other things) any carnivores and omnivores, herbivores that are not ruminants, any ruminants that do not have split hooves, shellfish (including shrimps and lobsters), unscaled and finless fish, blood, food offered to idols, or the meat of living or strangled animals. The Seven Laws of Noah, which Jews believe gentiles must follow, also forbid consuming the meat of living animals. Denominational views Nicene Christianity In Nicene Christianity, including Catholicism, Eastern Orthodoxy, Lutheranism, Anglicanism, and Reformed Christianity, there exist no dietary restrictions regarding specific animals that cannot be eaten. This stems from Peter the Apostle's vision of a sheet with animals, described in the Bible, in Acts of the Apostles, Chapter 10, when Saint Peter was told that "what God hath made clean, that call not thou common". The Seventh-day Adventist Church follows the Old Testament's Mosaic Law on dietary restrictions,
