I'm with those who say that this church has the right to decide what kind of people it wants working for it, but I'm not so sure I'm ready to consign this woman to hell for getting pregnant two months out of wedlock. Of course, that's only me. The way I see things, premarital sex isn't a sin; it's simply not a good idea.
