Romans 14:5

¹⁶Let no one therefore judge you in eating or drinking, or with respect to a feast day or a new moon or a Sabbath day, ¹⁷which are a shadow of the things to come; but the body is Christ’s.

²³But he who doubts is condemned if he eats, because it isn’t of faith; and whatever is not of faith is sin.

⁹But now that you have come to know God, or rather to be known by God, why do you turn back again to the weak and miserable elemental principles, to which you desire to be in bondage all over again? ¹⁰You observe days, months, seasons, and years.

⁷However, that knowledge isn’t in all men. But some, with consciousness of an idol until now, eat as of a thing sacrificed to an idol, and their conscience, being weak, is defiled.

¹⁹And by this we know that we are of the truth and persuade our hearts before him, ²⁰because if our heart condemns us, God is greater than our heart, and knows all things. ²¹Beloved, if our hearts don’t condemn us, we have boldness toward God;

¹⁴I know and am persuaded in the Lord Jesus that nothing is unclean of itself; except that to him who considers anything to be unclean, to him it is unclean.

¹¹And through your knowledge, he who is weak perishes, the brother for whose sake Christ died.
