I'm trying to replicate lyrics as shown in the red box (the Roman

1/ Lyric options are *stacked* and separated by a horizontal line

The following uses TextSpanner for the separating line and the Lyrics
context is aligned to a NullVoice.

\new NullVoice = "aligner" {

g4 a8 a4 a8 a4
}
\new Lyrics \lyricsto "aligner" {

Through our Lord Jesus Christ, your Son,

%%---------------------------------------------------------
Note that \stopStackedLyric requires a separate note in the NullVoice.
Its note value affects the length to the right of the horizontal line.
I used a somehow similar solution for function theory symbols, based on
the snipped lsr.di.unimi.it/LSR/Item?id=967

All the best,
