The simplest solution is
ErsteStimme = { c''8 b' b' a' g' g' f' e' }
ZweiteStimme = { a'8 a' g' f' f' e' d' c' }
DritteStimme = { e'8 f' c' d' e' e' b a }
VierteStimme = { c'8 d' a b c' b g f }
\score {
\new Staff <<
\new Voice <<\voiceOne \ErsteStimme \ZweiteStimme>>
\new Voice <<\voiceTwo \DritteStimme \VierteStimme>>
>>
}
This solution will even combine rests if they happen in one and
the same voice.
However, if you have simultaneous rests in all the four parts,
then you will see
them duplicated, which may or may not be what you want. There
have been
several workarounds proposed in the mailing lists and LSR to
merge the rests.

Is it possible to combine four parts into two voices on one
staff, ideally with one voice stems up and the other voice stems
down? I've gotten as far as two voices combined into one voice
with stems in the direction I want, but every time I add the
other voice, I either lose the two voice configuration, or I
lose the stem settings. For reference, I've been playing with
the following as my example.
ErsteStimme = { c''8 b' b' a' g' g' f' e' }
ZweiteStimme = { a'8 a' g' f' f' e' d' c' }
DritteStimme = { e'8 f' c' d' e' e' b a }
VierteStimme = { c'8 d' a b c' b g f }
OneAB = {
<<
\set Staff.printPartCombineTexts = ##f
\partcombine
<<\stemUp \ErsteStimme>>
<<\stemUp \ZweiteStimme>>
>>
}
TwoAB = {
<<
\set Staff.printPartCombineTexts = ##f
\partcombine
<<\stemDown \DritteStimme>>
<<\stemDown \VierteStimme>>
>>
}
\score {
\new Staff {
<<
<<\stemUp \OneAB>>
<<\stemDown \TwoAB>>
>>
}
}
I also tried <<\new Voice = "1" \with {\remove Rest_engraver}
{\OneAB} \new Voice = "2" \with {\remove Rest_engraver}
{\TwoAB}>>, and <<{\OneAB}\\{\TwoAB}>>, and various things
involving \stemUp and \stemDown, and I just can't seem to get it
work.
