>> muslims believe ismaaiyl, not isaac, was the son abraham was called upon to sacrifice. but the essence of the story is the same across the fthree religions. is it heart breaking to think that this patriarch, this person that we believe is the father of our religions was this close to committing murder? killing his son? >> i don't know if it's heart breaking or not, but i know that it's eye opening and that it's important because abraham introduces the idea. you can kill in the name of god. and i think it's important for everybody to understand that this idea is embedded in these biblical stories. this is not all, you know, kumbaya and can we all live in peace and say, oh, you know, you like butterflies and love your children, we can all get along. >> and yet the story is not an endorsement of killing in the name of god. >> so it's a test.
