DEUTORONOMY 14:6-8
6 And every beast that parteth the hoof, and cleaveth the cleft into two claws, and cheweth the cud among the beasts, that ye shall eat.
7 Nevertheless these ye shall not eat of them that chew the cud, or of them that divide the cloven hoof; as the camel, and the hare, and the coney: for they chew the cud, but divide not the hoof; therefore they are unclean unto you.
8 And the swine, because it divideth the hoof, yet cheweth not the cud, it is unclean unto you: ye shall not eat of their flesh, nor touch their dead carcase.
1Ti 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
1Ti 4:2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
1Ti 4:3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
1Ti 4:4 For every creature of God is good, and nothing to be refused, if it be received with thanksgiving:
1Ti 4:5 For it is sanctified by the word of God and prayer.
2Ti 4:2 Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
2Ti 4:3 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
2Ti 4:4 And they shall turn away their ears from the truth, and shall be turned unto fables.
Some people will depart from the truth of the Bible and accept a different interpretation based on the occult, and reverence for mother nature.
The time will come they will not want to hear the truth of the Bible but want to hear it according to their own lusts which is when the antichrist pushes that false interpretation with all religions interpreted that way.
Which is a trick of the devil to get them to think all religions are compatible.
Which they acknowledge Jesus but not as Lord and Savior.
Since they reverence nature they will not allow the eating of animals.
But God said all meat is good to eat now because it is a spiritual covenant so it is clean.
Col 2:14 Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;
Col 2:15 And having spoiled principalities and powers, he made a shew of them openly, triumphing over them in it.
Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days:
Col 2:17 Which are a shadow of things to come; but the body is of Christ.
Jesus took away the physical ordinances of Israel which includes the separation between clean and unclean animals.
So let no one judge you in meats.
The physical ordinances had no bearing on spiritual salvation but only applied during the Old Testament physical covenant with physical blessings.
In the New Testament love is the fulfilling of the law.
But if a person believes they cannot eat pork and they eat it then it is a sin.
Even though it is not a sin if they acknowledge the truth.
