Sister of battle (from warhammer 40k) as a 3.5/pathfinder character?

[Reprimand]

So I'm not sure to where to place sisters of battle on one hand they get access to heavy armor can fight and are zealous fanatics but they hate almost all sources of magic so a cleric or favored soul wouldn't really make sense. Inquisitor would be kind of close but does anyone know any faith based witch hunting classes without magic or revolve around anti magical measures?

Paladin with the ACF that grants bonus feats instead of spell slots or Crusader seem like they'd both fit fairly well.
Bonus points if you get the Desert Wind discipline on the Crusader, 'cause, y'know. Burning the heretics.

How about one of the drago classes (I always forget which is which), reflavouring the auras as miracles of your devotion and the breath weapon as your flamethrower?
