>> where have all of the christians gone? >> they are afraid to come. >> they are afraid of all of the turmoil and fighting that has plagued this area. >> this bethlehem used to be 100 percent christian. now it stands only above 35. >> i talked with people who used to wait in line for hours to get into the church of the nativity. now it looks like you can walk right in. >> absolutely. the door we will be going through. >> so this is the traditional birth place of jesus? >> this is the traditional birth place. there is very little doubt about the city and for us the probability about 85 percent that the church is actually built over the right place. we have two different versions one in luke where mary and joseph start from nazareth and matthew where mary and joseph are native of bethlehem. that's why jesus is born here.
