“The day of the LORD is near for all nations. As you have done, it will be done to you; your deeds will return upon your own head.” (Obadiah 1:15)
Obadiah is the shortest book in the Old Testament: a single chapter of twenty-one verses pronounced entirely against Edom. Edom, the nation descended from Esau, Jacob's twin brother, had a long history of enmity with Israel. When Babylon destroyed Jerusalem in 587 BC, Edom rejoiced, blocked the escape routes, and handed over fugitives. The ancient sibling rivalry becomes the occasion for the most focused national oracle in the prophetic literature.
The pride of your heart has deceived you, you who live in the clefts of the rocks and make your home on the heights, you who say to yourself, who can bring me down to the ground? Though you soar like the eagle and make your nest among the stars, from there I will bring you down, declares the LORD. On the day you stood aloof while strangers carried off his wealth and foreigners entered his gates and cast lots for Jerusalem, you were like one of them. The day of the LORD is near for all nations. As you have done, it will be done to you; your deeds will return upon your own head.
The Catechism identifies the principle of reciprocal justice in Obadiah as the expression of the divine moral order: what is done to the vulnerable will be done to the doer (CCC 2302).
Brothers and sisters, as you have done, it will be done to you; your deeds will return upon your own head. Edom stood aloof, gloated, blocked the fugitives, handed over the survivors. The deed became the sentence. The moral universe curves: whatever you do to the suffering of others returns to you. Stand with the suffering rather than against them. The return is coming.
Lord God, let the day of the LORD find us standing with the suffering, not against them. Through Christ our Lord. Amen.
