Romans 14:3
The one who eats everything must not treat with contempt the one who does not, and the one who does not eat everything must not judge the one who does, for God has accepted them. — Exouthenizo (treat with contempt, regard as nothing) and krino (judge, separate, condemn) are both forbidden. God's proslēpsis (reception, acceptance) of both proves both have standing. Neither side owns authority to judge the other's conscience.
