"Defend the weak and the fatherless; uphold the cause of the poor and the oppressed." (Psalm 82:3)
Psalm 82 is one of the most unusual psalms, depicting God presiding over a divine assembly and rendering judgment on lesser spiritual authorities who have failed in their duties. How long will you defend the unjust and show partiality to the wicked? The specific indictment is their failure to protect the vulnerable: Defend the weak and the fatherless; uphold the cause of the poor and the oppressed. Rescue the weak and the needy; deliver them from the hand of the wicked. These spiritual powers, called gods in verse 6, have been entrusted with justice and have failed it. They will fall like mere mortals.
The psalm is quoted by Jesus in John 10:34 to make a point about divine authority and human dignity. The Catechism draws from this the Church's social teaching: the defence of the vulnerable, the widow, the orphan, the poor, is not an optional extra for the people of God but the non-negotiable content of justice as God understands it (CCC 2448). Any exercise of authority, human or spiritual, is judged by the same criterion: did you defend the weak?
Brothers and sisters, the standard Psalm 82 sets for those in authority is clear: defend the weak, uphold the poor, rescue the needy. This applies to every person who holds any kind of responsibility over others: parents, employers, pastors, politicians. The final verse is a prayer for God himself to arise and judge the earth, because only he will do it with perfect justice. Until he does, we carry the mandate ourselves.
Rise up, O God, judge the earth, for all the nations are your inheritance. And while we wait for your final justice, make us instruments of it: defenders of the weak, advocates for the poor, voices for the voiceless. Through Christ our Lord. Amen.
