5 One person esteems one day as better than another, while another esteems all days alike. Each one should be fully convinced in his own mind.

22The faith that you have, keep between yourself and God. Blessed is the one who has no reason to pass judgment on himself for what he approves. 23But whoever has doubts is condemned if he eats, because the eating is not from faith. For whatever does not proceed from faith is sin.
