"We must respond to all tragic circumstances of pregnancy from the unshakeable foundation of two indisputable premises: human life begins at conception, and it is always wrong to intentionally kill an innocent human being. The unborn child’s right to life and liberty is given by his or her Creator, not by his or her parents or by the state. The right to life is inalienable: that is, not to be trespassed upon by another."
"When the life of the mother is truly threatened by her pregnancy, if both lives cannot simultaneously be saved, then saving the mother’s life must be the primary aim. If through our careful treatment of the mother’s illness the pre-born patient inadvertently dies or is injured, this is tragic and, if unintentional, is not unethical and is consistent with the pro-life ethic. But the intentional killing of an unborn baby by abortion is never necessary." -- From the Official position statement of the Association of Pro-Life Physicians
