I'm tired of all the confusion over food. Why? and can you give me a plain and simple answer?
(2Co 6:14-18) Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in them; and I will be their God, and they shall be my people. Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the uncleanthing; and I will receive you, And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.
There is the simple answer, not my words.
Just a small note: This verse tell us we should not be "unequally yoked together with unbeliever" -- "unequally" is the key word here. We would have to leave this planet in order not to have any associaltions with the world, or with unbelievers in general. We are called to be separatist, but at certain times, among the Aposltes teaching, they did teach a believer should not have anything to do with unbeleivers. Paul had given instructions to this effect and then did a 180, realizing he had given and unrealistic teaching. He corrects this and make better sense of our life on this earth while in the flesh. This is one of the reason, too, some trying to restore the Old Covenant, don't like Paul all that much. Here is what Paul said in correcting a previous teaching --
(1Co 5:9) I wrote unto you in an epistle not to company with fornicators:
(1Co 5:10) Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must you needs go out of the world.
(1Co 5:11) But now I have written unto you not to keep company, if any man that is called a brother be a fornicIator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat.
I think you get the point. This is also a truth when it comes to foods. Eat the wrong foods and suffer the physical consequences. They say you are what you eat, so we should eat well, a balanced diet of good foods. We know from the diet outline YHWH gave to the people of Israel that there were food considered not fit for human consumption. Even Noah knew of the clean and unclean animals (Gen 7:2).
I gave the simple answer and if you want more on this go to -- Clean and Unclean Food
