Yahweh was clear from the beginning about what we could and couldn't eat. Leviticus 11 and Deuteronomy 14 provide a list of animals that are not to be eaten as food; and included in this list of "unclean" foods are some of man's favorites: pork, shrimp, lobster, crab, catfish, squid, rabbit, squirrel, etc. - things that were meant to be the "garbage disposals" of the world! The New Testament, on the other hand, seems to indicate that God changed His mind somewhere along the line:
MARK 7:18 And he said to them, "Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, 19 because it does not go into his heart, but into his stomach, and is eliminated?" (Thus he declared all foods clean.)
A footnote in the Aramaic English New Testament provides insight:
This chapter showcases one of the greatest discussions of oral versus written Jewish law that exists in these writings of the Renewed Covenant. In many ways this presages the heated exchanges that would be recorded in the Talmud some 200 years later. However, a major misunderstanding of this verse found its way into the modern translations with the parenthetical comment "in so doing Y'shua declared all foods clean."
Neither Aramaic nor early Greek manuscripts include this in the text, which is clearly an attempt by Gentile or Christian editors to abandon Torah's dietary laws. The point being established is that if you plot things like murder, lies, adulteries and so forth, then why be concerned about the food you eat, when weightier things are making you much more unclean than your food? Even if a person kept a perfectly kosher diet, but had such unclean thoughts, such a one would rank among the most unkosher of people. See Luke 11:40.
ROMANS 14:14 As one who is in the Lord Jesus, I am fully convinced that no food is unclean in itself. But if anyone regards something as unclean, then for him it is unclean.
A footnote in the Aramaic English New Testament states:
The context of this discussion (verse 2) concerns meat versus a vegetarian diet. There is no discussion here about unclean foods according to Torah, because this is already clearly understood by Greek followers of Mashiyach. However, mainstream Christians twist this verse to teach that unclean food was made clean by Paul, which is a lie.
Paul was joined together with the other Shlichim in Jerusalem when the Ruach haKodesh spoke through Ya'akov HaTsaddiq, and instructed the non-Jewish converts to avoid unclean foods; i.e., foods sacrificed to idols, and blood. Notice also in Acts 15:20-21 that the expectation of the non-Jewish converts was that they would learn Moshe (Torah) as they grew in their relationship with Mashiyach and his people.
ACTS 10:10 He became hungry and wanted something to eat, and while the meal was being prepared, he fell into a trance. 11 He saw heaven opened and something like a large sheet being let down to earth by its four corners. 12 It contained all kinds of four-footed animals, as well as reptiles of the earth and birds of the air. 13 Then a voice told him, "Get up, Peter. Kill and eat." 14 "Surely not, Lord!" Peter replied. "I have never eaten anything impure or unclean." 15 The voice spoke to him a second time, "Do not call anything impure that God has made clean."
Many read the above and assume YHWH is telling Peter that "all animals are okay to eat, now - so, go ahead and eat!" But this is NOT what this is saying. Here is an analogy to help clear this up:
You are the parent of a 13 year old who wants to go see an R-rated movie. Your child begs you and you say NO! The child says WHY? You say, here, touch this hot stove....The child says "No, it's hot, you taught me not to touch a hot stove!" To which you say: "That's right, then don't question me when I say you cannot see an R-rated movie!"
So in Acts 10:13 when YHWH is saying "kill and eat", He is the parent soliciting the response from the child (Peter), and Peter gives the proper response: "No, I would not eat unclean animals, you taught me that". To which YHWH responds in verse 15: "That's right, now what I have cleansed, no longer consider unholy!"
Peter learns this meaning of his dream when he tells others about the dream at the beginning of Acts 11. Then in Acts 11:17-18 it becomes clear:
17. If therefore Elohim gives in an equal way the gift to Gentiles, those who believe in our Master Y'shua the Mashiyach, as also to us, who was I that I should be able to hinder Elohim." 18. And when they heard these words they became silent and they praised Elohim. And they were saying that, "Perhaps Elohim has given the Gentiles repentance to life."
A footnote in the Aramaic English New Testament explains:
Gentiles are called to enter into the Malchut Elohim to follow Mashiyach and observe Torah; this is not about the consumption of unclean food. Y'shua casts demons into a herd of swine Matthew 8, Mark 5, Luke 8. Swine meat is unclean, demons are unclean; Y'shua destroys both. Peter never ate unclean animals before or after this vision; followers of Y'shua don't eat unclean foods. The Hellenized Christian church endorsed eating unclean foods, because non-Jews have always eaten it as a cultural normative.
It is a continuum of pagan culture. Isaiah 66:17-24 clearly prophecies of a rebellious people who dine on swine's flesh, eat mice and choose to defy the Word of YHWH and His Mashiyach. Gentiles must not assume that these teachings single them out as unclean; Yehudeans are equally as unclean when choosing to defy YHWH and His Mashiyach (see Haggai 2:14; Ezekiel 44:22; Ezra 9:10-10:1; Isaiah 30:6-12; 65:2, 3; Jeremiah 5:22-31).
It is very important to differentiate between that which is Kosher according to YHWH, and religious "tradition." If unclean food is prohibited for Jewish followers of Y'shua, it is also prohibited for non-Jewish followers; the Kingdom of Elohim is not divided. If unclean food has been proven unhealthy, then it is unhealthy for Jewish and non-Jewish bodies alike; there is One Mashiyach and One Torah.
If you still have some doubts, please take a look at what Paul wrote here:
2 Corinthians 6:16. Or what agreement has the temple of Elohim with that of demons? For you are the temple of the living Elohim; as it is said, I will dwell among them, and walk among them, and will be their Elohim, and they will be my people. 17. Wherefore, you come out from among them, and be separate from them says Master YHWH; and don't come near the unclean thing, and I will receive you; 18. And will be to you a Father, and you will be sons and daughters to me, says Master YHWH the Almighty.
It would be unwise to eat something unclean if you wish to be a son or daughter of YHWH!
Those who don't know their Bibles very well will argue that, since the death of Jesus, we can eat whatever we want. But, since Malachi 3:6 declares that God does NOT change, why would He have changed his mind about what constitutes "clean" and "unclean" foods? Why would the foods listed in Leviticus 11 and Deuteronomy 14 now be okay to eat?
