I think mostly that Strength. He's a pretty beefy knight, guy shouldn't be going around with D-Rank Strength on foot. More in league with Iskander or Medusa on hitting power.

Well, if you think of the three miracles as something like command seals, you could get basically the same effect out of it if you wanted--and the other useful abilities. Power buffs for a critical fight, the spacial teleportation, breaking through a shield or the like you otherwise couldn't. All you're basically doing right now is giving yourself marginally better Magic Resistance.
