Hellbred Paladins can cast any Sanctified or Corrupt spells.
If they take a feat (Heretic of the Faith), they can stretch their class-based vows to essentially allow them to USE the above Corrupt spells (properly speaking, if you make extreme force allowable vs. evil people...)
Now, combo this with Battle Blessing, and smile (note: I know some people (Kell, I'm looking at you) say that Battle Blessing affects spells gained through Prestige Paladin. I don't agree with this position.).
I especially love having Absorb Knowledge and Absorb Strength on a Paladin. I really do.
"Thurdon, what are you doing?"
"Eating this orc's brain."
"Why?"
"To gain its knowledge, duh. Don't worry, Pelor is OK with this."
And that, my friends, is your average Paladin of Pelor. Grab a level in Binder, and go ahead and HEAL away that Sanctified damage as it tears its way through your unholy, technically undead flesh.
