This is verse 9 of Psalm 97, used today in the readings for Transfiguration:
Because you, O LORD, are the Most High over all the earth,
exalted far above all gods.
As Christians, we read this with a triple focus: then, now, and yet to come.
Then: There are reasons for believing that Psalm 97 was written after the return from Exile and rebuilding of the Temple in Jerusalem. By that time, Jews were convinced that there were no other “gods”–and they would understand the reference here as meaning false gods of the Gentile nations, or “other heavenly beings” such as angels, good or bad, who are subject to God’s sovereignty.
Now: Christians would read it similarly, and could see the “LORD” as referring to Christ after the Resurrection. We see the Transfiguration of Jesus as allowing Peter, James, and John a glimpse of his post-Resurrection glory and exaltation by his Father. Of course, their “glimpse” has been passed on to us later Christians in the New Testament.
Yet-to-come: It can also refer to the End of Time, the Time of the Second Coming as we Christians consider it, the Day of Judgment, or the glorious coming of the One who will restore all things in justice and peace, the One our Jewish brethren still await.
