Nothing in the Bible directly says anything against abortion; therefore, it's not a matter of following or not following the church teachings as it is opinion.
oh and also, the baby is technically a parasite off of its mother until it's born, so she has the choice of whatever she wants to do with it, whether it be to have an abortion or go through with it.
and also, usually the dad is out of the picture and the mom can't raise the child, and usually with a married couple they'll decide on it together. So everyone has agreed.
and seriously, i really don't feel like talking about this anymore. If you really want to have an intelligent Christian debate go talk to a pastor or something. I'm not trained to say anything of the Christian religion.
and please ponder this for a while:
