I did not say Paul was teaching His people to have faith in food.
That's not the complete sentence. Paul continues his sentence by explaining exactly what he means here by "departing from the faith" and lists two different doctrines of demons that lead people to do just that (exactly that, depart the faith). All in one big long sentence. The part you keep leaving out.
Here, in this very sentence, to depart the faith means to:
1) forbid marrying and
2) insist on abstaining from foods that God created for sharing
Bull. Did not Eve and Adam have faith that the forbidden fruit was good to eat and desiriable? Yes. Did that faith come from God? No.
Genesis 3:6 (LEB) When the woman saw that the tree was good for food and that it was a delight to the eyes, and the tree was desirable to make one wise, then she took from its fruit and she ate. And she gave it also to her husband with her, and he ate.
Genesis 3:17 (LEB) And to Adam he said, “Because you listened to the voice of your wife and you ate from the tree from which I forbade you to eat, the ground shall be cursed on your account. In pain you shall eat from it all the days of your life.
1 Timothy 4:7 (LEB) But reject those worthless myths told by elderly women, and train yourself for godliness.
Oh, almost forgot. Please post the Scripture that says:"The only faith there is, comes from God."
