Modern teachers are confused concerning Peter's vision that takes place within Acts chapter 10, and are spewing out what are obviously false teachings if you actually read the passage.
They are totally missing the very point of the vision, and instead teaching that it strongly urges us to stop obeying what YHWH told us about clean and unclean in his Law, and that we should eat the things that YHWH has told us are an abomination to eat.
"Abomination" is a very strong word from the scriptures, so this isn't something one should take lightly.
QUICK ANSWER: There is no commandment given in Acts 10, and neither is there any instruction given saying to ignore a previous commandment.
Also if there was, Peter is not 1 in authority to give us commandments.
The unclean animals in Peter's vision represented gentiles(foreign people), not unclean animals, it really had nothing to do with animals and us eating them.
The point and meaning of the vision was to not call the gentiles that have been cleansed by YHWH common, defiled, or unclean, they're saved just like we are, they're made clean when they join themselves to YHWH, they're no longer a gentile but grafted in.
Anyway after Peter's vision and experience, he fully understood that the righteous non-Hebrews were just as clean as the righteous Hebrews, and that the Father accepts all men no matter what their "race".
Since the beginning of my repentance and returning to YHWH to serve him with all of my heart, I've had a steady stream of people trying to get me to sin against YHWH and no longer care about his Word by bringing up Acts chapter 10, and they try to convince that it says in Acts 10 that it is okay to eat whatever we desire.
Also, some seem to twist Acts 10 and say the very point of this vision is that it's directed at the people who are still obeying the Law of their maker, and it's telling them to stop, as if obeying is not in line with the truth and it is the Law keepers who are missing some point and being blind.
Acts 10 says no such thing that they claim, it is only blind guides who are stating such nonsense, and those who are saying these things are easily put to shame because the simple text, if you actually read it, plainly contradicts those false statements of theirs.
1st off, if any supposed scripture tells us to ignore the word of YHWH, then it is not really scripture from him, if Acts 10 said such then it would indicate a huge problem.
Modern people tend to treat clean and unclean commandments like they're really no big deal or like they're lesser commandments,
but let me remind everyone that the very 1st sin of man that brought death into the world was the transgression of a commandment dealing with what we can and can not eat!
Disobeying is disobeying, it doesn't matter what it's concerning.
Please do not fall for the weak attempts of men to try and justify their love for eating more than their love for YHWH.
They're lusting with their tongues for flesh that YHWH has said is an abomination to eat, detestable.
We have an example from the Bible where YHWH saved his people out of Egypt and they wandered in the wilderness for some time.
Some people allowed their lusts of their tongue to cause them to be evil and dishonor YHWH, they complained against him, and even acted like they wished they were still slaves in Egypt over this, totally disregarding all of the great and gracious works YHWH had just done for them and the love he had shown to them, just because they were foolishly not satisfied with the food that he himself provided for them.
YHWH decided to give them what they wanted, and so much of it that they would despise it, and a plague broke out among them that killed many of them, and that place was named "The graves of craving", also meaning "The graves of lust".
The book of Acts like the rest of the Bible never says to disobey YHWH, rather Acts multiple times fully teaches us to obey YHWH if we read in context.
I will not write out all of Acts 10 to keep this as simple as possible, so I will just explain it and you can go read Acts 10 in context for yourself afterward, to see nowhere does it say to eat unclean animals and ignore the word of YHWH.
There was a gentile(foreigner) named Cornelius in Caesarea who feared YHWH along with all of his household, and he generously gave alms to the people and prayed to Elohim always.
An angel appeared to Cornelius in a vision and told him to send men to the disciple Peter and bring him to the house of these gentiles and Peter would instruct them in what to do.
Acts 10:5 "Now send men to Joppa, and send for one Simon who is called Peter. He is lodging with Simon, a tanner, whose house is by the sea. He will tell you what you must do"
Now after this, Peter who they were in the process of going to fetch, went up on his roof to pray and he fell into a trance and seen a vision, in the vision he seen all manner of animals on the earth coming down from the heavens, and a voice spoke and said to Peter to rise and to kill and eat, however Peter would not do so.
Acts 10:14 "But Peter said, Not so Lord! For I have never eaten anything common or unclean", because he had never in his life eaten anything that was common or unclean"
But after Peter refused, a voice said to Peter that what Elohim has cleansed he should not consider "common".
The source texts actually look to say the word "defiled".
Acts 10:15 "And a voice spoke to him again the 2nd time, What Elohim has cleansed you must not consider defiled"
So at this point in the passage, many people who do not really invest time into learning the word, and their heart is not really set on understanding the truth, will stop reading there, and then spread teachings for people to eat whatever they want, even though YHWH commanded us not to do that.
However, I assure you, the pig at the supermarket YHWH has not cleansed, and there are future prophecies yet to be fulfilled specifically talking out against those who eat pork!
So it is important to focus, this is not a commandment for mankind, nowhere will you see YHWH in Acts 10 giving us a commandment, and neither did he say anywhere in Acts 10 that he was changing his mind on a previous commandment that he gave us to keep forever.
Peter did not have the authority to give us commandments either, Moses was put in that authority to be a mediator, and Yahushua as well.
If a normal prophet comes to us and claims we should add to or take away from the Law, then we know they're not telling the truth.
This misconception over Acts 10 can be combined with the other twisted teachings, and all of these misconceptions together can give people an illusion that these sort of things really are a common theme taught throughout the new testament, when they're not, and their leaders are just misleading them to see the text in that twisted view.
So moving on, right after Peter's vision it actually let's us know that Peter didn't even know yet what the vision meant!
Acts 10:17 "Now while Peter wondered within himself what this vision which he had seen meant, behold, the men who had been sent from Cornelius had made inquiry for Simon's house, and stood before the gate, and they called and asked whether Simon, whose surname was Peter, was lodging there. While Peter thought about the vision, the spirit said to him, behold 3 men are seeking you, arise therefore, go down and go with them, doubting nothing, for I have sent them"
So if it says Peter didn't know what it meant yet, then I am not sure why so many people are jumping to conclusions already since 1st off, Peter didn't even understand what it meant, and 2nd this indicates it was a vision with a meaning that has to be figured out.
So up to this point that meaning has not been explained out in the text.
Also notice here that the spirit told Peter to "arise" and go down and go with them. In his vision he was also told to "arise".
So while Peter was trying to figure out what the vision meant, the gentile men showed up looking for him, then the spirit told Peter do not hesitate with them because they had been sent.
Now skipping forward a bit to verse 28, we are then told the meaning of the vision has been realized!
Peter has figured out the meaning of the vision that he had been given.
The unclean animals in the vision represented the gentile(foreign) men, not actual unclean animals. It really had nothing to do with eating animals, but it was a lesson to Peter, and us.
Acts 10:28 "Then he said to them, you know how unlawful it is for a Jewish man to keep company with or go to 1 of another nation, but Elohim has shown me that I should not call any man common or unclean"
Acts 10:34 "Then Peter opened his mouth and said, in truth I perceive that Elohim shows no partiality, but in every nation whoever fears him and works righteousness is accepted by him"
If you didn't know why such a vision was needed, it was an issue among the Hebrews in those days, thanks to the blind "religious" leaders, that they were making it a tradition to start treating foreigners poorly as if they were all defiled, and tried to separate Hebrew people from the foreigners and not interact with them, and were even putting up literal walls to separate them, and this was not good to do, at least not in the ways they were doing it.
It became part of their culture and many men stumbled with such things.
Just like today the people were misguiding others to hate entire races of people rather than hating the works of sin that some were doing, and they were punishing the innocent along with the guilty.
We can see examples of Peter not yet being totally pure in the truth with what he should do concerning this, it is even mentioned at Galatians 2:11 how Paul even rebuked Peter because he was acting hypocritical with the gentiles.
Galatians 2:11 "Now when Peter had come to Antioch, I withstood him to his face, because he was to be blamed, for before certain men came from James he would eat with the gentiles, but when they came he withdrew and separated himself, fearing those who were of the circumcision, and the rest of the Jews also played the hypocrite with him, so that even Barnabas was carried away with their hypocrisy, but when I saw that they were not straightforward about the truth of the gospel, I said to Peter before them all, If you, being a Jew, live in the manner of Gentiles and not as the Jews, why do you compel Gentiles to live as Jews?"
Another thing to note, Acts 10:28 Peter mentions that it is not lawful for Jewish men to interact with gentiles, but it's important to realize that he is referring to a man-made law among the Jews in those days, and not an actual law from YHWH, no such commands exist in the actual Law but rather we are commanded repeatedly to love the gentiles and accept them as 1 of us if they join themselves to YHWH!
Leviticus 19:34 "But the foreigner that dwells with you shall be to you as one born among you, and you shall love him as yourself, for you were foreigners in the land of Egypt, I am YHWH your Elohim"
So understanding all of this, it was plainly saying to not call the gentiles that have been cleansed by YHWH common, defiles, or unclean!
All of those who serve YHWH are accepted by him and the sacrifice of Yahushua the messiah cleansed all men of their sins and uncleanness, not just only 1 race of man!
(The Messiah did not die to cleanse pork bacon!)
So please do not be led astray by false witnesses of the Bible who have not read all of it in context.
Read the scriptures in full and consider them all and you will not be able to be led astray by those spreading these obvious false doctrines.
If you eat that which YHWH has told you that you must never eat, then you're sinning against YHWH our Father, and the Messiah died to pardon our sins, if we keep sinning intentionally we're making it to where he died for nothing for us.
Hebrews 10:26 "For if we go on sinning deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, but only a fearful expectation of judgment and of raging fire that will consume the opposers"
Matthew 5:19 "Whosoever therefore shall break one of these least commandments and shall teach others to do the same, shall be called the least in the kingdom of the heavens, but whosoever shall do and teach them the same, shall be called great in the kingdom of the heavens"
I will finish up this point with this thing to note.
At Acts 10:14 when Peter refused to eat unclean creatures when a voice told him to, this actually shows Peter was still keeping clean and unclean laws after Yahushua had been sacrificed and had risen, it shows that the Messiah never told Peter to do away with clean and unclean meats!
