Romans 14:5-10

In the same way, one person regards a certain day as more sacred than another, and another person regards them all alike. There is nothing wrong with having different personal convictions about such matters. For the person who observes one day as especially sacred does it to honor the Lord. And the same is true regarding what a person eats. The one who eats everything eats to honor the Lord, because he gives thanks to God, and the one who has a special diet does it to honor the Lord, and he also gives thanks to God. No one lives to himself and no one dies to himself. While we live, we must live for our Master, and in death we must bring honor to him. So dead or alive we belong to our Master. For this very reason the Anointed One died and was brought back to life again, so that he would become the Lord God over both the dead and the living. Why would you judge your brothers or sisters because of their diet, despising them for what they eat or don’t eat? For we each will have our turn to stand before God’s judgment seat.
