Is this an ironic claim or what (link)?
All humor aside, God alone knows the heart.
Since I don't pray to the dead, I don't have to worry about disembodied spirits trying to motion "stop" (cf. link).
But then again, if I didn't listen to Moses' prohibition of necromancy and idol-worship, I'm not going to believe if someone were raised from the dead.
P.S. I note that not all Roman Catholics are equally enthused (link).
