The first step is to convert your literal \markup expression to
scheme. Then substitue the part that should change with a variable name,
finally wrap this expression inside a define-markup-command expression.

The argument to your \deacon command, a markup, will be the justified
part.

#(define-markup-command (deacon layout props what-is-said)
                        (markup?)
  (interpret-markup layout props
    (markup #:pad-markup 3 
              #:large #:line (#:hspace 9
                              #:with-color (x11-color 'firebrick) #:italic 
"Deacon:"
                              #:override '(line-width . 60) what-is-said))))

\markup \deacon \justify {
  What the deacon says.
}
