That’s a secular humanist argument about the Old Testament that isn’t faithful to the Bible.
The prohibitions against things like eating pork are worded like, “this shall be an abomination UNTO YOU.”
“5 And the coney, because he cheweth the cud, but divideth not the hoof; he is unclean unto you. 6 And the hare, because he cheweth the cud, but divideth not the hoof; he is unclean unto you. 7 And the swine, though he divide the hoof, and be clovenfooted, yet he cheweth not the cud; he is unclean to you. 8O their flesh shall ye not eat, and their carcase shall ye not touch; they are unclean to you.” (Leviticus 11)
“Unto you” is used again and again. And the Lord makes clear that these prohibitions were given by Him in order to separate and sever the Israelites from other people. These prohibitions would effectively put up a wall between His Chosen People and everyone else:
“22 Ye shall therefore keep all my statutes, and all my judgments, and do them: that the land, whither I bring you to dwell therein, spue you not out. 23 And ye shall not walk in the manners of the nation, which I cast out before you: for they committed all these things, and therefore I abhorred them. 24 But I have said unto you, Ye shall inherit their land, and I will give it unto you to possess it, a land that floweth with milk and honey:
“I am the LORD your God, which have separated you from other people. 25 Ye shall therefore put difference between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground, which I have separated from you as unclean. 26 And ye shall be holy unto me: for I the LORD am holy, and have severed you from other people, that ye should be mine.” (Leviticus 20)
True- and it’s a secularist argument that is irrelevant to today and issues like we are discussing- First off I’m not jewish- second, we are no longer under the law- Thirdly- God instructed Peter that eating such foods no longer taints a person’s condition
As You pointed out- those rules were very specific to Israel Whom God required to separate themselves from an Ungodly world- and to be an example to the world as a nation set apart- Before the law was done away with, that was the only way for man to be cleansed- After Christ died- that all changed- We are once and for all cleansed by the blood of the Lamb- We don’t need to ‘keep cleansing’ ourselves by abstaining any longer- and again God made certain foods ‘clean’ —
“there is nothing from without a man that entering into him can defile him” (Mark 7:15).
So you’re going to make an argument that when the word “you” is used it only applies to the person being addressed? All those times Jesus said “you” didn’t apply to you personally, but only to others? You have some really selective perceptions.
