Abortion,,, can it be ok for a Christian to have one in some cases?

I want to state that I am 100% against abortion in all cases, but I have to make an exception. I am going thru a very rough dilemma here in our household. Our daughter, who is 16 went to Church with us every Sunday, was brought up in a very Republican and very Religious Household by me and her mother, and went to a private school. However, it turns out that she is pregnant with a black persons baby. I was wondering, is there any other recourse/ road we could go down besides abortion? I will not have race mixture going on in my household at all, our reputation in our southern Georgia community would be destroyed , and my daughter would have a mutt to look at for the rest of her life. I have made it very clear I wont tolerate it. I have discussed this matter at length with our immediate family and our pastor, who says that we can most definitely make a very slight exception in this case as the races were not meant to be together, but I was wondering what verse in the Bible I can use?
