A little more than a month ago, I watched
the Concordia University Wisconsin chapel service from 29 August. The hymn was "By All Your Saints in Warfare" (with the stanza for The Martyrdom of St. John the Baptist inserted). I noticed a small feature in the first two lines: "By all Your saints in warfare, / For all Your saints at rest." They're sung to these musical phrases from the tune "King's Lynn":
Both times, the phrase "all Your saints" is sung to notes of all different pitches (G A D and G F D, respectively), giving some sense of the entirety of these "all"s.
