When the pope's away, the devil will prey

>>> word exorcism can bring out emotions, skepticism or terror, the idea of something taking control of your body is just creepy. you probably remember this 1973 classic.

>> it's the power. holy water ! it's the power of christ that compels you. god the father commits you.

>> aah!

>> god the son commands you.

>> aah!

>> even 40 years later that's a haunting vision and call it a coincidence, divine intervention or something else but "the exorcism" is out today.

>> whoa.

>> less than 24 hours after the pope officially resigned.

>> weird.

>> coincidence? no.

>> some believe right now with no pope in place the church is especially vulnerable to a great evil slipping in. in the guest spot today is dr. pena, associate professor who probably sizes in folklore and philosophy. thank you for joining e my.

>> my pleasure.

>> thank you. let me get this out for the viewers and some of us here at the table. how do i avoid being possessed by the devil ? that's number one.

>> well, the easy answer is you have to keep on the straight and narrow which is usually the worst thing to keep because, you know, we are in a world that's full of contradiction. but if you want to avoid the devil, you have to avoid all the things that can lead you to him.

>> how do i find out -- how can i tell, for example, say my colleague steve, how can i tell if he's being possessed or maybe just having a really bad day ?

>> well --

>> what are the telltale signs?

>> well, there are kind of signs from subtle to extreme. but usually the idea of the -- the demonic possession is manife manifested, first thing a avoidance of sacred things for obvious reasons. and then there are other physical manifestations. extraordinary force. blasphemy. all kind of anti-social and anti-faith behavior. and usually that is --

>> steve is very a "t."

>> professor, i got to say i'm not buying this exorcism or possession stuff at all. it's interesting for movies, but for real like this is real people really get possessed by the devil ? are we talking about sort of misunderstanding mental i will snns.

>> you know, we're talking about religion and when we talk about religion, it's very hard to really quantify because we're talking about faith. and that is something that you cannot put under the microskocope. my role is not to say if it's true or not, but the thing is many people do believe that there are evil spirits . many people also believe there are good spirits. and if the religion or the religious practice assumes that there are all niece negative spirits, then it is obvious sooner or later they will try to interfere in human affairs, and after all, if you look at the gospels, you know, one of jesus' duties was to expel demons as well. so it's just ingrained in christianity to believe that demons can possess people.

>> and professor, how closely do the firsthand accounts of people who think they have witnessed an exorcism, witnessed demonic possession , how closely do those accounts match with the sort of exorcism movies?

>> very close. you know, there's so many accounts since the beginning of recorded history. i mean, it's not a phenomena that only affects christianity. there are many -- in many religious the idea of possession is very common both good and bad. so, you know, there are these ideas that at person that is possessed by a spirit usually enters the realm of supernatural feats and supernatural force and supernatural knowledge. so, yes, these movies are usually drawing from that tradition.

>> okay. interesting stuff. professor, thank you so much for joining us.

>> my pleasure. thank you for having me.

>> up next, the crazy thing that happened in times square this week and why toure says this flash mob shows times have changed. [ male
