Bible: Rom 14:5-6
14:5 One person regards one day holier than other days, and another regards them all alike. 1 Each must be fully convinced in his own mind. 14:6 The one who observes the day does it for the Lord. The 2 one who eats, eats for the Lord because he gives thanks to God, and the one who abstains from eating abstains for the Lord, and he gives thanks to God.
