Dont Pig Out

"but that we write to them that they abstain from things contaminated by idols and from fornication and from what is strangled and from blood. 21 For Moses from ancient generations has in every city those who preach him, since he is read in the synagogues every Sabbath.”- Acts 15
"But concerning the Gentiles who have believed, we wrote, having decided that they should abstain from meat sacrificed to idols and from blood and from what is strangled and from fornication.”- Acts 21

In acts 15 and 21 we see this command from the Apostles that those gentiles who are turning to God to avoid meat sacrificed to Idols. While there is meat that was clean, like sheep and bulls, the primary sacrifice for the major false gods is pig. 


Greek deities

• Demeter and Persephone: Pigs were an especially important offering for these goddesses of fertility and the underworld, particularly during the Thesmophoria festival. The rituals were linked to agricultural fertility, with the remains of buried piglets mixed with seeds to ensure a good harvest.
• Chthonic deities: Pigs were a common offering in purification and fertility rites for gods associated with the earth and underworld, which were also considered "unclean". The entire pig would often be incinerated in a holocaust, where the offering is wholly burnt.
• Zeus: As king of the gods, Zeus typically received more prestigious offerings, such as a bull. However, specific cults of Zeus, such as Zeus Meilikhios, could receive cakes baked in the shape of pigs or goats.
• Hermes: Cakes shaped like pigs were traditional offerings for Hermes, the messenger god. 

Roman deities

• Mars: The most distinctive and traditional Roman offering to the war god Mars was the suovetaurilia, a triple sacrifice of a pig (sus), a sheep (ovis), and a bull (taurus). This rite was used to purify land and ensure victory in battle.
• Household gods: A suovetaurilia was also offered to household gods at the agricultural festival of the Ambarvalia to ensure the fertility of the fields.
• Other uses: In a Roman context, a pig was a common victim for a piaculum, a sacrifice meant to atone for a sacrilege. 

Norse deities

• Frey: In Norse mythology, the god of fertility Frey is associated with the magical boar Gullinbursti ("golden-bristled"). Historically, a "sacrificial boar" was used in Yule celebrations, and the boar was a symbol of power and royal lineage.
• Æsir and Einherjar: In Valhalla, the boar Sæhrímnir is killed and eaten every night by the gods and fallen warriors, only to be resurrected the next day. 

Egyptian deities

• Osiris and Set: In ancient Egypt, pigs were offered to the gods. In particular, pigs were sacrificed to Set, the god associated with Upper Egypt. 
  
  

Scripture has several mentions about those who eat abominations and follow their appetites rather than obeying God.  

Psalm 141:4

"Do not incline my heart to any evil thing, To practice deeds of wickedness With men who do iniquity; And do not let me eat of their delicacies.  

Romans 16:17-18

"Now I urge you, brethren, keep your eye on those who cause dissensions and hindrances contrary to the teaching which you learned, and turn away from them.

18For such men are slaves, not of our Lord Christ but of their own appetites; and by their smooth and flattering speech they deceive the hearts of the unsuspecting.

Philippians 3:18-19

18For many walk, of whom I often told you, and now tell you even weeping, that they are enemies of the cross of Christ, 19whose end is destruction, whose god is their appetite, and whose glory is in their shame, who set their minds on earthly things.

Isaiah 65:1-5
“I have spread out My hands all day long to a rebellious people, Who walk in the way which is not good, following their own thoughts, 3 A people who continually provoke Me to My face,Offering sacrifices in gardens and burning incense on bricks; 4 Who sit among graves and spend the night in secret places;Who eat swine’s flesh, And the broth of unclean meat is in their pots. 5 “Who say, ‘Keep to yourself, do not come near me, For I am holier than you!’ These are smoke in My nostrils,A fire that burns all the day."

Isaiah 66:15-17

"For behold, the LORD will come in fire And His chariots like the whirlwind, To render His anger with fury, And His rebuke with flames of fire.  16For the LORD will execute judgment by fire And by His sword on all flesh, And those slain by the LORD will be many. 17“Those who sanctify and purify themselves to go to the gardens, Following one in the center, Who eat swine’s flesh, detestable things and mice, Will come to an end altogether,” declares the LORD."

In fact, It's Nicolaitan doctrine to disregard God's prohibition against unclean meat. The deeds of the Nicolaitans are specifically rebuked by Christ in Revelation 

Acts 6:5
The statement found approval with the whole congregation; and they chose Stephen, a man full of faith and of the Holy Spirit, and Philip, Prochorus, Nicanor, Timon, Parmenas and Nicolas, a proselyte from Antioch.

Revelation 2:2-7
 ‘I know your deeds and your toil and perseverance, and that you cannot tolerate evil men, and you put to the test those who call themselves apostles, and they are not, and you found them to be false; 3 and you have perseverance and have endured for My name’s sake, and have not grown weary. 4 But I have this against you, that you have left your first love. 5 Therefore remember from where you have fallen, and repent and do the deeds you did at first; or else I am coming to you and will remove your lampstand out of its place—unless you repent. 6 Yet this you do have, that you hate the deeds of the Nicolaitans, which I also hate. 7 He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will grant to eat of the tree of life which is in the Paradise of God.’

Revelation 2:13-17
‘I know where you dwell, where Satan’s throne is; and you hold fast My name, and did not deny My faith even in the days of Antipas, My witness, My faithful one, who was killed among you, where Satan dwells. 14 But I have a few things against you, because you have there some who hold the teaching of Balaam, who kept teaching Balak to put a stumbling block before the sons of Israel, to eat things sacrificed to idols and to commit acts of immorality. 15 So you also have some who in the same way hold the teaching of the Nicolaitans. 16 Therefore repent; or else I am coming to you quickly, and I will make war against them with the sword of My mouth. 17 He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, to him I will give some of the hidden manna, and I will give him a white stone, and a new name written on the stone which no one knows but he who receives it.’

They were a people who used Christian liberty as an occasion for the flesh, against such Paul warned (Gal 5:13). The enticement to such a course of action was the pagan society in which Christians lived where eating meat offered to idols was common. Sex relations outside marriage were completely acceptable in such a society. The Nicolaitans attempted to establish a compromise with the pagan society of the Graeco-Roman world that surrounded them. The people most susceptible to such teaching were, no doubt, the upper classes who stood to lose the most by a separation from the culture to which they had belonged before conversion.- Encyclopedia of the Bible, Biblegateway

"The sect of the Nicolaitans had its apostles' and prophets like the great church. The Apostles were the missionaries. In Ephesus the members of the church had experienced their influence and had driven them out with scorn and shame. In Thyatira a certain woman, who seems to have been particularly dangerous, is attacked as a prophetess.2 John had already given her one warning and granted her time for repentance. Now he threatens her and her followers with judgment of death if they persist in their sinful ways.3 5. This is all the information concerning the Nicolaitans which the Apocalypse of John furnishes. From the writings of the church fathers, however, we gain some further knowledge: (a) Irenaeus of Asia Minor describes them as "a branch of the movement falsely called 'gnosis"' (iii. i i. ), and regards them as forerunners of Cerinthus. This he did not learn from the Apocalypse, but from tradition. Probably he knew more about them and their teaching than he felt it necessary to tell. That they were still existing in his time is implied in i. 26. 3 (cf. also Clement of Alexandria). b) Tertullian also knew more (on the basis of tradition) than he tells. This is evident from the fact that he classes them with the satanic sect of the Cainites (de Praescr. 33.4 Cf. also Adv. Marc. i. 29; de Pudic. 19). In the epistle of Jude, also, the false teachers are described as going "in the way of Cain." c) The gnostic system of the Nicolaitans, which is referred to in the Apocalypse, in Irenaeus, and in Tertullian, is described in its main features by Hippolytus in the Syntagma.s It was a thoroughly dualistic"

 In his treatise ad Miannaeam Hippolytus says further that the Nicolaitans taught that the resurrection had already taken place in faith and baptism, and that there was no resurrection of the flesh; that they laid the greatest stress upon faith and baptism is shown by their particular type of Christianity.2 From Hippolytus' account we see that he must have had in his possession a good fund of knowledge concerning the Nicolaitans. d) Clement of Alexandria, who gives us information concerning the person of Nicolaus which does not appear elsewhere (see the exposition below), says nothing concerning the teaching of the Nicolaitans because the particular connection in which he mentions them gives no occasion to speak of their doctrine (questions of asceticism). However, he does say that these "lascivious goats" justify their wicked actions with a word of their teacher, Nicolaus: "It is proper to abuse the flesh." They no longer existed in his day. e) We have a striking statement from Victorinus of Pettau. He says that the Nicolaitans had taught "that food offered to idols might be exorcized and eaten and that anyone who might be a fornicator might obtain peace on the eighth day."

 So, the idea that through prayer "God made all the unclean animals now clean" is not Biblical, its a doctrine that Christ Himself rebuked. Christ states that He hates these deeds. As the aforementioned verses from Isaiah show- regarding the return of Christ in judgement- Those who are eating the swine's flesh will experience steep consequences.
