Way I managed this:
use glyph of judgement and the 2 word of glory glyphs (so you can ranged attack with it and get a small damage buff)
do not use glyph of exorcism
1) blow cooldowns and nuke Wrath until adds spawn
2) run in a wide circle round wrath keeping censure stacked (occasional judgement) and use execution sentence
3) use ranged judgement/exorcism on adds, finishing them off with hammer.
4) spend hp to heal self whenever needed otherwise use wog to damage adds
4) when cooldowns available, use extra hammers on wrath.
5) when mirror image part starts, kite adds through them and use hotr/ds near images.
some of the adds will catch you up and deal a fair amount of damage, but you can use crusader strike on these, you should be able to survive by using sacred shield+wog to self heal
unfortunately the adds do not proc crusader so don't bother using flash of light
took me 10mins+ to get kill.
