From Designer Note: Just as most clerics battle undead, the exorcist cleric battles malevolent ghosts, possessing fiends, and binders of spirits. The exorcist cleric is a standard cleric but with spontaneous casting as described in Unearthed Arcana by Wizards of the Coast, a swap of turn/rebuke undead for exorcism- related abilities, less armor, more class skills, and preset domains.
