Hmm .... they don't really break it down that well (full results of churchgoing Catholics vs. non-churchgoing, etc) but Catholics SHOULD be more likely to say they communicate with the dead because we pray to the saints in Heaven for their intercession and view seances, tarot, etc seriously (in a negative way) because we believe in the existence of of Satan and his minions.
Depends on the meaning of "dead," as Jesus mentioned in last Sunday's Gospel reading.
A logical deconstruct of biblical warnings about the "dark arts," would lead to the conclusion that there would be no need for warnings if the paranormal was not possible.
If this is so, what is the Catholic response to a situation like the one that recently occurred in Washington State?
