“At that time gifts will be brought to the LORD Almighty from a people tall and smooth-skinned, from a people feared far and wide.” (Isaiah 18:7)
Isaiah addresses a message to the land of whirring wings along the rivers of Cush, which sends ambassadors by sea in papyrus boats. He calls to all who inhabit the world: when a banner is raised on the mountains, look! When a trumpet sounds, listen! The LORD will look down from his dwelling place; he will wait and watch. For before the harvest, when the blossom is gone and the flower becomes a ripening grape, he will cut off the shoots with pruning knives. At that time gifts will be brought to the LORD Almighty from a people tall and smooth-skinned, from a people feared far and wide, an aggressive nation of strange speech, whose land is divided by rivers.
The Catechism draws from Isaiah's universal oracles the principle that God's sovereignty extends over every nation: the nations beyond Israel's horizon are within the scope of the God who rules from Zion (CCC 56).
Brothers and sisters, even Cush, the distant nation at the edge of the known world, will bring gifts to the LORD Almighty. The universality of the Kingdom of God is not a New Testament innovation. No nation is beyond the reach of this God.
Lord God, gifts will be brought to you from every people. Draw all nations to your mountain. Through Christ our Lord. Amen.
