Hymn with three verses with refrain following

[Br. Athanasius Pelletier]

How can I modify this (which Frescobaldi made) to make a hymn with three verses with the refrain at the end.  The refrain has it's own notation.

\version "2.13.35"

\include "english.ly"

\header {
  title = "All Creatures of Our God and King"
  % Remove default LilyPond tagline
  tagline = ##f
}

\paper {
  #(set-paper-size "letter")
}

global = {
  \key ef \major
  \time 3/2
  \partial 2
}

sopranoVoice = \relative c'' {
  \global
  \dynamicUp
  % Music follows here.
  
}

verseOne = \lyricmode {
  \set stanza = "1."
  % Lyrics follow here.
  
}

verseTwo = \lyricmode {
  \set stanza = "2."
  % Lyrics follow here.
  
}

verseThree = \lyricmode {
  \set stanza = "3."
  % Lyrics follow here.
  
}

\score {
  \new Staff { \sopranoVoice }
  \addlyrics { \verseOne }
  \addlyrics { \verseTwo }
  \addlyrics { \verseThree }
  \layout {
    \context {

    }
  }
