Paul asks that the one who is weak in faith be welcomed, not for quarrels over opinions. One person believes he may eat anything, while the weak person eats only vegetables. The one who eats must not despise the one who abstains, and the one who abstains must not pass judgment on the one who eats, for God has welcomed him. Who are you to pass judgment on the servant of another? To his own master he stands or falls, and the Lord is able to make him stand.
One person esteems one day as better than another, while another esteems all days alike. Each should be fully convinced in his own mind, and each acts in honor of the Lord and gives thanks to God. None of us lives to himself, and none of us dies to himself: whether we live or die, we are the Lord's. For this purpose Christ died and lived again, that he might be Lord of both the dead and the living. We will all stand before the judgment seat of God, and each will give an account of himself.
Therefore let us not pass judgment on one another any longer, but resolve not to put a stumbling block in a brother's way. Paul is persuaded in the Lord Jesus that nothing is unclean in itself, but it is unclean for anyone who thinks it unclean. If your brother is grieved by what you eat, you are no longer walking in love; do not destroy by your food the one for whom Christ died. The kingdom of God is not food and drink but righteousness, peace and joy in the Holy Spirit.
Let us pursue what makes for peace and mutual upbuilding. The 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. But whoever has doubts is condemned if he eats, because the eating is not from faith; for whatever does not proceed from faith is sin.
