Perhaps too much but I couldn't find decent refs regarding "Muslim issues"

A couple of hits, but nothing too enlightening.

OTOH the churches have PR officers nowadays and award huge contracts to ad agencies, sio I think officer is certainly an option.

The hits for "Islamic affairs representative" and the names of said representatives suggest he (she?!?) would be someone who works from the other end - and this reflects my own gut feeling.

i.e.:
- His principal duties/fields of work/activity comprise ...

My logic: the previous entence already identifies him as "Synodalbeauftrager ... für den christlich-islamischen Dialog", so there's no need for repetition. Unlike in German, we tend not to invent synonyms just for the sake of it (classic example: Berlin = die Metropole an der Spree). It's considered bad style (i.e. especially in the very next sentence).
An sich ist er schon ein "Islamic Relations Officer" - but I'd only state that further down in the text. ;-)
