What if you had a vision where God told you to do something that you knew was wrong?
Well, He hasn't done that to me.
If I felt like God was telling me to do something that I thought or knew was wrong, I would figure that it was not God speaking but either my self or satan. If the voice persisted, I would question my opinion of what is right and wrong and I would question my sanity.
Again, you mean? God would never do a thing like that again? (Acts 10. )
Jesus had already taught that the old food laws were no longer obligatory as recorded in Mark 7:18-23
18 He replied to them, “So you too are without understanding? Don’t you see that nothing going into a person from outside can make him unclean? 19 For it doesn’t go into his heart but into his stomach, and it passes out into the latrine.” (Thus he declared all foods ritually clean.) 20 “It is what comes out of a person,” he went on, “that makes him unclean. 21 For from within, out of a person’s heart, come forth wicked thoughts, sexual immorality, theft, murder, adultery, 22 greed, malice, deceit, indecency, envy, slander, arrogance, foolishness…. 23 All these wicked things come from within, and they make a person unclean.” CJB
The way I understand this verse, the words that are shown in parentheses in the CJB are Mark's comment on what Jesus said. In the Thompson KJV those words are in red as if Jesus said them. There are differences of opinion among those who translate/edit/provide different versions as to whether that phrase is part of Jesus' words or a comment by the author of that Gospel.
Exactly. So, does everyone here believe that God will not again change His mind about what He requires of people?
In context, the pharisees were accusing Jesus and his disciples of eating without washing their hands prior to eating.
Mark 7
1 Then came together unto him the Pharisees, and certain of the scribes, which came from Jerusalem.
2 And when they saw some of his disciples eat bread with defiled, that is to say, with unwashen, hands, they found fault.
3 For the Pharisees, and all the Jews, except they wash their hands oft, eat not, holding the tradition of the elders.
4 And when they come from the market, except they wash, they eat not. And many other things there be, which they have received to hold, as the washing of cups, and pots, brasen vessels, and of tables.
5 Then the Pharisees and scribes asked him, Why walk not thy disciples according to the tradition of the elders, but eat bread with unwashen hands?
See what Jesus said:
6 He answered and said unto them, Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me.
7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
8 For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
9 And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
13 Making the word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
Jesus' rebuke was AGAINST the tradition of men being UPHELD as the commandment of God.
That is the context of that scripture.

I don't know that it is God changing His mind.
Under the dispensation of Law, certain foods were forbidden.
Since we are under grace, we no longer have to comply with the old Law.
