"Love does no harm to a neighbour. Therefore love is the fulfilment of the law." (Romans 13:10)
Let everyone be subject to the governing authorities, for there is no authority except that which God has established. The authorities that exist have been established by God. Whoever rebels against the authority is rebelling against what God has instituted, and those who do so will bring judgment on themselves. Paul wrote this when Nero was emperor, before the persecutions began. The Church has always read this passage with nuance: the legitimate authority of civil government is a gift of God for the ordering of society, and Christians are obliged to obey it. But the Catechism is equally clear that this obligation has limits: when civil authority requires what is contrary to the moral order or the rights of persons, citizens are obliged to refuse to obey (CCC 2242). The obedience of Romans 13 is not absolute; it operates within the higher obedience of Acts 5:29.
Pay taxes, give revenue where it is owed, show respect and honour. Let no debt remain outstanding except the continuing debt to love one another. The commandments against adultery, murder, stealing, and coveting are summed up in the single command: love your neighbour as yourself. Love does no harm to a neighbour. Therefore love is the fulfilment of the law. Paul echoes the teaching of Jesus in Matthew 22: the whole Law and the Prophets hang on the two love commands. Love does not abolish the specific commandments; it fulfils them, going beyond mere external compliance to the interior disposition that would never want to harm a neighbour.
The hour has already come to wake up from slumber, because our salvation is nearer now than when we first believed. The night is nearly over; the day is almost here. So put aside the deeds of darkness and put on the armour of light. Clothe yourselves with the Lord Jesus Christ and do not think about how to gratify the desires of the flesh. The eschatological urgency of Paul's ethics: every day brings the return of Christ closer, and every day is a day to be clothed in Christ rather than in the deeds of darkness.
Brothers and sisters, love does no harm to a neighbour. Before every action, that simple test: does this harm the person in front of me? If it does, love forbids it, regardless of whether a specific commandment names it. If it does not, love may permit or even require it. This is the fulfilment of the law: not the minimum compliance that avoids guilt, but the active orientation toward the good of the neighbour that goes beyond compliance to genuine care.
Lord God, the night is nearly over and the day is almost here. Help us put aside the deeds of darkness and clothe ourselves with the Lord Jesus Christ. Let love be our only outstanding debt: paid daily, never discharged, owed to everyone we meet. Through Christ our Lord. Amen.
