In decrying the doctrine of double effect (for which, ironically, we owe a debt to Catholic theology), Rev. John Ehrich, the medical ethics director for the Diocese of Phoenix stated: "She consented in the murder of an unborn child...There are some situations where the mother may in fact die along with her child. But — and this is the Catholic perspective — you can't do evil to bring about good. The end does not justify the means."
The notion of a medical ethics director abiding not by principles of medical ethics, but by substituting (or overlaying) his or her system informed by faith, is against all tradition of medicine as an activity designed to better the lot of the ill, rather than to better the lot of the decision-maker or his church. Decision-making in medical ethics should shun 'absolute' (deontological) approaches and instead adopt frameworks that help guide the clinician or other agent to the best possible outcome for the particular case being considered by incorporating a wide range of moral considerations. Such a system is exemplified by the decision-making approach from the University of British Colombia detailed here (PDF), or the 'Ethox structured approach' from the Ethox Centre at the University of Oxford, which I reproduce below:
Compare the principalist and reflective decision-making process depicted here which includes elements such as 'Does this option respect the persons involved', with the deontological approach used by Rev. John Ehrich in the case of Sister McBride. His ethics come from the Ethical and Religious Directives for Catholic Health Care Services, Fourth Edition, which states, for example:
Directive 36: Compassionate and understanding care should be given to a person who is the victim of sexual assault...It is not permissible, however, to initiate or to recommend treatments that have as their purpose or direct effect the removal, destruction, or interference with the implantation of a fertilized ovum.The difference between the two methods of decision-making, the Ethox approach designed to produce the best outcome for the patient, and the Catholic approach which will frequently have the opposite effect, is so stark as to negate the latter as a system of medical ethics; it is instead dogma, which should not be tolerated by medicine.
But let us submit ourselves to dogma for a moment. We glance at Directive 47 of the above document:
Operations, treatments, and medications that have as their direct purpose the cure of a proportionately serious pathological condition of a pregnant woman are permitted when they cannot be safely postponed until the unborn child is viable, even if they will result in the death of the unborn child.In light of such provision, the justice administered to Sister McBride appears rather summary and in stark contrast to the leniency shown to the paedophilic actions of thousands of priests.
