If you were to make a priest that deals in Exorcism, What powers would you give him ??

(Holy) Water/Mental Manipulation with Force of Will and Soul Mastery!

I am considering a Demons/Pain MM with this theme.  The demons have been extracted from innocent victims and are obligated to serve.

Psy powersets tinted white/gold, or a human-form PB make the most sense to me, given the whole divine theme. Psychic Dom especially feels like it'd fit an Exorcist character fairly well, binding it's enemies with the light. @ZemX's Idea is a really cool take too though, Staff with some pool/epic powers to fill it out would be neat!
