Our very brief first reading is taken from the magnificent fifty-fifth chapter of the book of the prophet Isaiah. This section of Isaiah—which stretches from chapter forty through chapter fifty-five—is one of the most theologically sophisticated and illuminating passages in the entire Old Testament. Nowhere is Israel’s theology of God more fully and clearly developed. And one of the principal points made in this section is that God is incomparable. Over and over again, Isaiah insists that God is radically other; that he is like no other being, even the most exalted.
