Vatican 'no problems' with Harry Potter (actually, it was the Secretary of the European Conference of Bishops who said, "I don't see any, any problems in the Harry Potter series," so consider the source.)
On the other hand, the chief exorcist of the Holy See, Fr. Gabriel Amorth, said in an article that "Behind Harry Potter hides the signature of the king of the darkness, the devil."
Im with an above poster here, this is probably not an infallibility issue. Pope Benedetto may just like the woman's book!
'because this is subtle seduction, which is deeply unnoticed and has direct effects in undermining the soul of Christianity before it can really grow porperly.'
Oh, good grief! What a complete waste of time. Hey, Benedict, if you are concerned about "undermining the soul of Christianity" I have come Catholic colleges and universities for you to look at along with the kook professors directing the anti-Catholic secret societies and kooky liberal social engineering at them (where you actually have some authority to stop such things).
Why do they whine about things they have absolutely no control or authority over while letting even DARKER and more sinister personalities run riot over their own colleges, universities, and seminaries??? What's going on? For God's sakes get rid of the creeps at the Catholic colleges and universities and forget about these stupid and tacky Harry Potter books!
