And if anyone is speaking on God's behalf and saying this they are speaking against the bible.
Romans 14:2
One person believes he may eat anything, while the weak person eats only vegetables.
I Corinthians 8:8
Food will not commend us to God. We are no worse off if we do not eat, and no better off if we do.
I Timothy 4:1-5
Now the Spirit expressly says that in later times some will depart from the faith by devoting themselves to deceitful spirits and teachings of demons, through the insincerity of liars whose consciences are seared, who forbid marriage and require abstinence from foods that God created to be received with thanksgiving by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with thanksgiving, for it is made holy by the word of God and prayer.
Romans 14:17
For the kingdom of God is not a matter of eating and drinking but of righteousness and peace and joy in the Holy Spirit
