One area where God's law has been disregarded is that of clean and unclean meats. God's law, applicable to all mankind, is vital for Christians to keep in order to grow in righteousness. The clean and unclean laws are mentioned early in God's Word, in the account of the Noachian Flood, when Noah was commanded to take seven each of every clean animal. After the Flood, Noah offered burnt offerings of every clean animal and bird, suggesting these laws were known and practiced from the earliest days of mankind, long before there were Jews or Israelites, indicating they are for all humankind. In Genesis 9:3, God tells Noah that every moving thing that lives shall be food, even as the green herbs, meaning mankind has authority to eat flesh within the same parameters as vegetation, excluding harmful meats just as poisonous plants are excluded. All reviewed scriptures confirm that the law concerning clean and unclean meats remains in effect today. Since God gives only good things and His law is holy, just, and good, we should trust that our Maker knows what is beneficial for His creatures and put His laws into practice in our lives, recognizing that at least their principles are still valid to help us live abundantly.

The biblical command regarding clean and unclean meats remains in force today, representing numerous laws that protect against physical and spiritual impurity, directly relating to the pursuit of holiness. This principle of being set apart for a special purpose undergirds the law, distinguishing God's people from surrounding nations. As the spiritual temple of God, Christians are tasked with cleansing themselves of fleshly defilements, perfecting holiness in all areas of life. The law of clean and unclean predates the Old Covenant, existing in Noah's time and possibly earlier, thus not becoming obsolete with the Old Covenant's passing. God provides specific lists in Scripture of foods that are clean or unclean, along with guidelines to identify unlisted foods. Christ did not abolish this law; His teachings addressed ritual washings, not the consumption of unclean meats, emphasizing that true defilement comes from a person's conduct. Similarly, Peter's vision did not nullify this law but taught against calling any person common or unclean. Paul's writings also do not permit eating unclean meats, focusing instead on sensitivity to others' consciences regarding clean meats offered to idols. In God's Kingdom, the distinction between clean and unclean will continue to be taught by the priesthood during the Millennium. In the New Jerusalem, nothing that defiles will be present, and all citizens will be holy, underscoring the ongoing relevance of adhering to the law of clean and unclean meats as preparation for this destiny.

The question of clean and unclean meats is a fundamental aspect of mankind's relationship with God, rooted in disbelief and a lack of trust in His instructions. From the beginning, God established distinctions between clean and unclean animals, though He does not explain why certain animals are deemed unclean, simply commanding not to eat them. This principle is introduced in a universal context in Genesis, long before Israel or the Old Covenant, indicating its application to all mankind. In Genesis 4, while clean and unclean are not directly mentioned, the concept is implied through sacrifices to God, aligning with detailed instructions later given in Leviticus 1 through 7, where only clean animals or birds were acceptable for sacrifice. At the time of Noah, as seen in Genesis 7 and 9, mankind already understood which animals were clean and unclean, with no change indicated in God's consistent instruction. God's command to Noah in Genesis 9:3-4, using the phrase "even as the green herb," clarifies that not all things are intended for food, just as not all green plants are edible. While the reaction to unclean flesh may not be immediate, unlike with poisonous plants, God eventually named specific animals as clean or unclean in Leviticus 11 and Deuteronomy 14, establishing these as part of the Old Covenant with Israel, yet their application remains universal and unchanged. These food laws, like the Ten Commandments, existed before the Old Covenant and continue beyond it, being fundamental to living a good life. Sacrifices, as detailed in Leviticus, symbolically represented Jesus Christ, whose life was free from defilement, reinforcing that only clean animals were suitable. In Isaiah 65:2-5, written around 750 BC, eating swine's flesh is still detestable to God, equated with idolatry. Even into the Millennium, as described in Ezekiel 40-44, what is unclean remains so, showing God's unchanging nature in this matter. In Mark 7, during Jesus Christ's ministry, a misunderstanding arises regarding food and defilement. Jesus Christ corrects the Pharisees, who were concerned with external dirt on food, not with unclean meats. His statement in Mark 7:19 about purifying all foods refers to common food, specifically bread, defiled by dirt from hands or utensils, not to flesh created unclean by God. He clarifies that physical dirt does not defile the spiritual heart, and His teaching does not alter the distinction between clean and unclean meats. God's principles regarding food remain constant, as He changes not, and His instructions are designed for mankind's good, complementing the bodies He created.
