Romans 14:5-6
One person regards a certain day above the others, while someone else considers every day alike. Each one should be fully convinced in his own mind. He who observes a special day does so to the Lord; he who eats does so to the Lord, for he gives thanks to God; and he who abstains does so to the Lord and gives thanks to God.
