If I understand what you are trying to do, I have run into similar
problems.  If you are trying to do what I will style (for lack of a
better term), "intermediate" chant notation (i.e., note heads only,
but using contemporary note heads with slurs as opposed to square
neumes or mensural heads), this is what I have been using:

\include "english.ly"
\version "2.7.14"

barOne = { \once \override Staff.BarLine #'bar-size = #2
           \bar "|" }
barTwo = { \once \override Staff.BarLine #'extra-offset = #'(0 . 2)
           \once \override Staff.BarLine #'bar-size = #2
           \bar "|" }

chant = \relative e' {
  \set Staff.autoBeaming = ##f
  \set Score.timing = ##f
  \override Staff.Stem #'transparent = ##t
  \override Staff.Stem #'length = #0
  \override Staff.TimeSignature #'transparent = ##t
  \key a \major
  \mark \markup {Antiphon \hspace #2 \italic{"Cf. Isaiah 35 : 4"} }
  e4 fs a a gs a( b gs) e4. \barOne
  e4( fs) a( a) \barTwo
  a( gs) a( b a4.) \bar "|"
  b4( a b) b cs a( b a4.) \barTwo
  fs4 a gs e4. e \bar "||"
}

text = \lyricmode {
  Say to those who are fright -- ened:_*
  Be strong,
  fear not!
  Here is our God,
  he comes to save us.
}

\score {
  <<
    \context Voice = staff \chant
    \lyricsto "staff" \new Lyrics \text
  >>
  \layout{
    indent = #0
  }
}
