It’s too bad that the lectionary only has three short verses of Psalm 72. It has some of the most marvelous imagery in the psalter. It’s a prayer for God’s blessing on the king, but asks more of him than any mortal could achieve: peace and justice throughout the land, saving the children of the needy, crushing their oppressors. Because of that ruler’s commitment to the poor, the afflicted, and all who who have no one to help them, all the tribes of the earth and their own kings shall bring homage and tribute to this just king.

Why is this important for the feast of the Epiphany?

The three magi in Matthew’s Gospel were Gentiles, from distant places. If even these recognized the newborn king—well, no wonder Herod was worried! And with good reason: he knew the psalms, and he knew he didn’t fit the description of the just king.

Authority brings with it responsibility. Those who enjoy power for its own sake may not realize it is given in order that they may serve others. Pope Francis is setting a good example in this regard, putting aside the pomp of centuries and moving toward the simplicity of early Christians.

But the psalm is not just about the king. If God requires the king to serve the poor, promote peace and do justice, then everyone who has any authority must do the same—not only national and religious leaders at all levels, but everyone: bosses, teachers, parents ... yes, and music directors, too.
