"Lift High the Cross"

Years ago, I wrote about the first half of the refrain in "Lift High the Cross."  Last month, I was thinking about the hymn again and realized something about the second half of the refrain:

(The tune is "Crucifer.")

The text is "Till all the world adore His sacred name."  The words in the phrase "all the world" are all sung to different pitches (spanning a sixth:  E G C), musically giving a sense of the breadth or entirety of that "all."
