Owe no one anything except to love one another, for he who loves another has fulfilled the law. For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not bear false witness,” “You shall not covet,” and if there is any other commandment, are all summed up in this saying, namely, “You shall love your neighbor as yourself.” Love does no harm to a neighbor; therefore love is the fulfillment of the law.
