I don't think you actually need tags. In this example, my extremely
limited Scheme only allows for a very old-fashioned two genders, but
someone who knows what they are doing could easily add more... Happy
Christmas music making!

\version "2.18.2"

ismale = ##f
%gender = "m" % manually set to m(ale), f(emale), n(eutral)

heshe = #(if ismale #{ he #} #{ she #})
hisher = #(if ismale #{ his #} #{ her #})
himher = #(if ismale #{ him #} #{ her #})

global = { \key c \major }

verse = \lyricmode {
  Filled with the Spir -- it, by \hisher earth -- ly la -- bours,
  Brought to your peo -- ple heal -- ing and com -- pas -- sion;
  Rais -- ing the fal -- len, re -- con -- cil -- ing sin -- ners,
  Glad -- ly \heshe served them.
}

music = {
  c' c' c' c' c' c' c' c' c' c' c'
  c' c' c' c' c' c' c' c' c' c' c'
  c' c' c' c' c' c' c' c' c' c' c'
  c' c' c' c' c'
}

  \new Voice = "mel" { \global \music }
  \new Lyrics \lyricsto "mel" { \verse }
