Did Peter's Vision of the Sheet Mean People & Food?

[Mary]

In Genesis 9 : 1-5 God speaks to Noah:

And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth.
And the fear of you and the dread of you shall be upon every beast of the earth, and upon every fowl of the air, upon all that moveth upon the earth, and upon all the fishes of the sea; into your hand are they delivered.
Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things.
But flesh with the life thereof, which is the blood thereof, shall ye not eat.
And surely your blood of your lives will I require; at the hand of every beast will I require it, and at the hand of man; at the hand of every man's brother will I require the life of man.

This is an edict for all mankind from Noah and his sons and forward. It did not end when God gave his commandments to Moses and the people of Israel, the purpose of which was to separate them from all other people:

Genesis 19: 1-6

In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai.
For they were departed from Rephidim, and were come to the desert of Sinai, and had pitched in the wilderness; and there Israel camped before the mount.
And Moses went up unto God, and the LORD called unto him out of the mountain, saying, Thus shalt thou say to the house of Jacob, and tell the children of Israel;
Ye have seen what I did unto the Egyptians, and how I bare you on eagles' wings, and brought you unto myself.
Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine:
And ye shall be unto me a kingdom of priests, and an holy nation. These are the words which thou shalt speak unto the children of Israel.

The food laws are symbolic of the separation between the children of Israel and all other nations. They were a means of keeping the Israelites separate, but with the coming and death and resurrection of Jesus Christ, this separation is removed. Peter's vision was to show Peter that no animal was unclean, and that all could be killed and eaten. The application of that was that people who kill and eat any animal are therefore also not unclean, and this application was was made clear to Peter by the invitation from Cornelius and God telling him to go to Cornelius.

If the vision only meant Peter could mix with the gentiles but not eat their food, what are we to make of these verses?:

1 Corinthians 10: 23 -27

All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.
Let no man seek his own, but every man another's wealth.
Whatsoever is sold in the shambles, that eat, asking no question for conscience sake:
For the earth is the Lord's, and the fulness thereof.
If any of them that believe not bid you to a feast, and ye be disposed to go; whatsoever is set before you, eat, asking no question for conscience sake.

and also:
Romans chapter 14:

Him that is weak in the faith receive ye, but not to doubtful disputations.
For one believeth that he may eat all things: another, who is weak, eateth herbs.
Let not him that eateth despise him that eateth not; and let not him which eateth not judge him that eateth: for God hath received him.
Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
One man esteemeth one day above another: another esteemeth every day alike. Let every man be fully persuaded in his own mind.
He that regardeth the day, regardeth it unto the Lord; and he that regardeth not the day, to the Lord he doth not regard it. He that eateth, eateth to the Lord, for he giveth God thanks; and he that eateth not, to the Lord he eateth not, and giveth God thanks.
For none of us liveth to himself, and no man dieth to himself.
For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord's.
For to this end Christ both died, and rose, and revived, that he might be Lord both of the dead and living.
But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ.
For it is written, As I live, saith the Lord, every knee shall bow to me, and every tongue shall confess to God.
So then every one of us shall give account of himself to God.
Let us not therefore judge one another any more: but judge this rather, that no man put a stumblingblock or an occasion to fall in his brother's way.
I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
But if thy brother be grieved with thy meat, now walkest thou not charitably. Destroy not him with thy meat, for whom Christ died.
Let not then your good be evil spoken of:
For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost.
For he that in these things serveth Christ is acceptable to God, and approved of men.
Let us therefore follow after the things which make for peace, and things wherewith one may edify another.
For meat destroy not the work of God. All things indeed are pure; but it is evil for that man who eateth with offence.
It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
Hast thou faith? have it to thyself before God. Happy is he that condemneth not himself in that thing which he alloweth.
And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
