In mainstream Nicene Christianity, there is no restriction on kinds of animals that can be eaten. This practice stems from Peter's vision of a sheet with animals, described in the Book of Acts, Chapter 10, in which Saint Peter "sees a sheet containing animals of every description lowered from the sky." Nonetheless, the New Testament does give a few guidelines about the consumption of meat, practiced by the Christian Church today; one of these is not consuming food knowingly offered to pagan idols, a conviction that the early Church Fathers, such as Clement of Alexandria and Origen, preached.
In the Ethiopian Orthodox Church, an Oriental Orthodox Christian denomination, washing one's hands is required before and after consuming food. This is followed by prayer, in which Christians often pray to ask God to thank Him for and bless their food before consuming it at the time of eating meals, such as breakfast. The wording of these mealtime prayers vary per Christian denomination, e.g. the common table prayer is used by communicants of the Lutheran Churches and the Moravian Church.
Slaughtering animals for food is often done with the trinitarian formula, although the Armenian Apostolic Church, among other Orthodox Christians, have rituals that "display obvious links with shechitah, Jewish kosher slaughter." The Bible, states Norman Geisler, stipulates one to "abstain from food sacrificed to idols, from blood, from meat of strangled animals".
In the New Testament, Paul of Tarsus notes that some devout Christians may wish to abstain from consuming meat that has been offered to idols if it causes "my brother to stumble" in his faith with God (cf. 1 Corinthians 8:13). As such, some Christian monks, such as the Trappists, have adopted a policy of Christian vegetarianism. In addition, Christians of the Seventh-day Adventist church typically follow the Bible's guidelines of what to eat and what not to eat. Some would even suggest they have the same kind of diet as the Jewish religious group. They only eat meat of a herbivore without spit hooves, birds without a crop and without webbed feet. They also don't eat shellfish of any kinds. They only eat fish with scales. As for any other animal, it is not considered as clean or worthy of eating. All vegetables, fruits and nuts are edible. Christians in the Anglican, Catholic, Lutheran, Methodist, and Orthodox denominations traditionally observe a meat-free day, especially during the liturgical season of Lent.
In Judaism, Jews are forbidden from consuming (among other things) blood, food offered to idols, or the meat of living animals or strangled animals. The Seven Laws of Noah, which Jews believe gentiles must follow, also forbid consuming the meat of living animals. 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." Christian diets are based, wholly or partially, on the aforesaid dietary laws.
With reference to medieval times, Jillian Williams states that "unlike the Jewish and Muslims methods of animal slaughter, which requires the draining of the animal's blood, Christian slaughter practices did not usually specify the method of slaughter". In actual practice, states Williams, European Christians have flexibly practiced both the method of draining the blood, and wringing the animal's neck to retain its blood as valuable food. According to Basheer Ahmad Masri, the "Jewish and the Christian methods of slaughter fulfill the Islamic condition of bleeding the animal". In contrast, David Grumett and Rachel Muers state that the Orthodox Christian Shechitah and Jewish Kosher methods of slaughter differ from the Muslim Halal (Dabh) method in that they require the cut to "sever trachea, oesophagus and the jugular veins" as this method is believed to produce meat with minimal suffering to the animal.
Christian denominations in the Adventist, Baptist, Methodist, and Pentecostal traditions either abstain from or prohibit the consumption of alcohol (cf. teetotalism). Other Christian denominations condone moderate drinking of alcohol, including the Anglicans, Catholics, Lutherans, and the Orthodox. However, all Christian Churches, in view of the Biblical position on the issue, universally condemn drunkenness as sinful.
Before Christianity, they could not eat certain things from certain animals (uumajuit), but after eating they can now do anything they want to.
In the meantime, Peter in Joppa has a midday vision in which he sees a sheet containing animals of every description lowered from the sky. He hears a voice from heaven telling him to "kill and eat." Peter is naturally taken aback, because eating some of these animals would mean breaking the Jewish rules about kosher foods. But then he hears a voice that tells him, "What God has cleansed, you must not call common [unclean]" (that is, you do not need to refrain from eating nonkosher foods; 10: 15). The same sequence of events happens three times.
Christ came for the Gentiles as well as the Jews (the real meaning of that vision in Acts 10:9;16) but he also calls us to look out for each other and not do things that will cause our brothers and sisters to stumble. In Corinthians Paul urges the believers to consider not eating meat when with people who assume that meat must be offered to idols before consumption: 'Food will not bring us close to God,' he writes. 'We are no worse off if we do not eat, and no better off if we do. But take care that this liberty of yours does not somehow become a stumbling block for the weak.' (1 Corinthians 8:8-9)
Clement of Alexandria and Origen also forbid eating meat dedicated to idolatry and partaking in meals with demons, which, by association, are the meals of fornicators and idolatrous adulterers. Marcianus Aristides merely testifies that Christians do not eat what has been sacrificed to idols; and Hippolytus only notes the interdiction against eating such food.
All the faithful should strive to pray seven times a day & at the following hours: Upon rising from bed in the morning & before eating & commencing any task. Wash your hands & pray standing.
The Christians do "Basema ab wawald wamanfas qeeus ahadu amlak" [in the name of the Father, the Son, and the Holy Spirit one God] and then slaughter. The Jews say "Baruch yitharek amlak yisrael" [Blessed is the King (God) of Israel].
By contrast, the most common mode of slaughtering four-legged animals among Christians in the nineteenth century was through the deliverance of a stunning blow to the head, usually with a mallet or poleax.
The Armenian and other Orthodox rituals of slaughter display obvious links with shechitah, Jewish kosher slaughter.
Nevertheless, toward the end of the chapter, Paul suggests that even Christians with strong faith may want to abstain from eating meat offered to pagan deities if any chance that their example will tempt fellow Christians of weaker faith into inadvertent idolatry. He concludes by saying, "Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble." (1 Corinthians 8:13)
Traditional Hindus and Trappist monks adopt vegetarian diets as a practice of their faith.
The main legally enforced prohibition in both Catholic and Anglican countries was that against meat. During Lent, the most prominent annual season of fasting in Catholic and Anglican churches, authorities enjoined abstinence from meat and sometimes "white meats" (cheese, milk, and eggs); in sixteenth- and seventeenth-century England butchers and victuallers were bound by heavy recognizances not to slaughter or sell meat on the weekly "fish days," Friday and Saturday.
Of the Eating of Meat: One should abstain from the eating of meat on Fridays and Saturdays, also in fasts, and this should be observed as an external ordinance at the command of his Imperial Majesty.
In the Orthodox groups, on ordinary Wednesdays and Fridays no meat, olive oil, wine, or fish can be consumed.
Both the Jewish and the Christian methods of slaughter fulfill the Islamic condition of bleeding the animal.
Protestants who called themselves "fundamentalists" (they believed in the literal truth of the Bible--Baptists, Methodists, Pentecostals) were dry.
Although the Jewish, Roman Catholic, Orthodox, Episcopal, and Lutheran traditions generally allow moderate drinking for those who can do so, it is simply incorrect to accuse them of condoning drunkenness.
Drunkenness was biblically condemned, and all denominations disciplined drunken members.
For most of Christian history, as in the Bible, moderate drinking of alcohol was taken for granted while drunkenness was condemned.
