You may work on something like that. Note that it won't work well
if the text is too large.

#(define-markup-command (columns layout props args) (markup-list?)
  (let ((line-width (/ (chain-assoc-get 'line-width props
                        (ly:output-def-lookup layout 'line-width))
                       (max (length args) 1))))
    (interpret-markup layout props
      (make-line-markup (map (lambda (line)
                               (markup #:pad-to-box `(0 . ,line- 
width) '(0 . 0)
                                 #:override `(line-width . ,line-width)
                                 line))
                              args)))))

\markup \columns {
  \column {
    "Kyrie eleison,"
    "Christe eleison,"
    "Kyrie eleison."
  }
  \column {
    "Herr, erbarme dich,"
    "Christus, erbarme dich,"
    "Herr, erbarme dich!"
  }
  \column {
    "Lord, have mercy,"
    "Christ, have mercy,"
    "Lord, have mercy."
  }
}

You may change the page breaker:

\paper {
  #(define page-breaking ly:minimal-breaking)
}

to avoid page breaks when there is still room to print text at the
bottom of a page. But then the page and line breaking of the pieces
won't be as fine as with optimal-breaking.

Use a top-level \markuplines, this will set the padding and spacing to 0
for the consecutive markups inside it, thus make them stick one to  
another.
