"O Christ, Our True and Only Light"

"O Christ, Our True and Only Light" was one of the hymns on Worship Anew a couple months ago (4 May, The Third Sunday of Easter), and I noticed a small feature in it.  The last two lines of the hymn are "And endless praise to You be giv'n / By all Your Church in earth and heav'n."  The second of these lines is sung to this musical phrase from the tune "O Jesu Christe, wahres Licht":

The phrase "all Your Church" is sung to notes of all different pitches (A B C), giving a slight sense of this entirety.
