"He said his entire family was baptized before leaving Tennessee for Los Angeles to protect themselves from evil, and he believes Satan is attacking his family."
This might work better:
Magic Circle against Evil Abjuration [Good]
Level: Clr 3, Good 3, Pal 3, Sor/Wiz 3
Components: V, S, M/DF
Casting time: 1 standard action
Range: Touch
Area: 10-ft.-radius emanation from touched creature
Duration: 10 min./level
Saving Throw: Will negates (harmless)
Spell Resistance: No; see text
All creatures within the area gain the effects of a protection from evil spell, and no nongood summoned creatures can enter the area either. You must overcome a creature’s spell resistance in order to keep it at bay (as in the third function of protection from evil), but the deflection and resistance bonuses and the protection from mental control apply regardless of enemies’ spell resistance.
A creature capable of any form of dimensional travel (astral projection, blink, dimension door, etherealness, gate, plane shift, shadow walk, teleport, and similar abilities) can simply leave the circle through that means. You can prevent the creature’s extradimensional escape by casting a dimensional anchor spell on it, but you must cast the spell before the creature acts. If you are successful, the anchor effect lasts as long as the magic circle does. The creature cannot reach across the magic circle, but its ranged attacks (ranged weapons, spells, magical abilities, and the like) can. The creature can attack any target it can reach with its ranged attacks except for the circle itself.
Arcane Material Component: A little powdered silver with which you trace a 3-footdiameter circle on the floor (or ground) around the creature to be warded.
