In
The Lutheran Service Book, "Forth in the Peace of Christ We Go" is sung to the tune "Angelus." In
Lutheran Worship, however, (where the title is shortened a bit to just "Forth in the Peace of Christ"), the hymn is sung to the tune "Lledrod." I noticed a small feature specific to this tune.
Near the end of the second verse, there's the line "With Christ the Servant-Lord of all," sung to this musical phrase:
"All" is sung with a melisma (Db C Bb), musically giving a sense of that entirety.
