I would not call, not eating pork a false teaching. If you do not think the Old Testament is relevant than that’s your opinion and that’s fine. But what did Jesus dying on the cross change about a pig? They are still unclean. God created them to clean the earth.
12 All who sin apart from the law will also perish apart from the law, and all who sin under the law will be judged by the law. 13 For it is not those who hear the law who are righteous in God’s sight, but it is those who obey the law who will be declared righteous.
7 What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, “You shall not covet."8 But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead. 9 Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. 10 I found that the very commandment that was intended to bring life actually brought death. 11 For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. 12 So then, the law is holy, and the commandment is holy, righteous and good.
1 Corinthians 6:19-20
19 You surely know that your body is a temple where the Holy Spirit lives. The Spirit is in you and is a gift from God. You are no longer your own. 20 God paid a great price for you. So use your body to honor God.
Mind body and soul need to be Intune with God and that includes taking care of your body as best as possible so we can be good examples and spread the Gospel. The US Gov is in with big pharma they want us sick, fat, and lazy. I’ll pass on anything they say about health!
Now things I would call false teaching are prosperity gospel and heliocentrism (sun does not move and is center of the universe). The bible clearly states both are false. Many cling more to man vs what the bible says. It is very easy to be deceived, just look at nasa lol! Biblical cosmology is the truth!
6 My people are destroyed for lack of knowledge: because thou hast rejected knowledge, I will also reject thee, that thou shalt be no priest to me: seeing thou hast forgotten the law of thy God, I will also forget thy children.
Most people are lazy and will not study deep and ask for discernment. If you do not study and try to learn many will be deceived and not make it. There are many false teachings that can lead you away from God, but I would not call avoiding eating pork that. Knowledge is power.
