It is known as unclean meat. Many Christian people also do not eat Pork.
God's Word describes the flesh of unclean animals as an ''abomination''. Leviticus 11:10-13, 20, 23, 41-42. and ''detestable'' (Deutoronomy 14:3) . and in light we are warned against consuming such meat. (Leviticus 11:43).
Read Leviticus 11 and Deutoronomy 14.
The book of Revelation, in describing the end-time events leading up to the return of Christ, uses the expression ''a haunt for everything unclean and hated bird!" (Revelations 18:2)
God is consistent and unchanging.
Mark 5: 1-13 records that Jesus crossed the Sea of Galilee by boat to the region of Gadara, a gentile (non-Jewish) area on the eastern shore. There He was met by a demon-possessed man from whom He would shortly cast out many evil spirits.
In this remarkable encounter, the demons requested that Jesus send them into a herd of 2000 swine/pigs. on a nearby hillside. Jesus granted their request, and, when the demons enter the swine, ''the herd ran violently down the steep place into the sea, and drowned in the sea' (verse 13).
Many have puzzled over this astounding incident in which Jesus precipitated the desctruction of a valuable herd of 2000 pigs - enough to feeld many thousands of people. Yet we should not be surprised when we understand the biblical instruction that these animals should never have be raised for food, and their owner was acting in defiance to God's laws.
