Brain Death and the Formation of Moral Conscience

In this article, we provide an update to Catholic ethicists and clinicians about the current status of Catholic teaching and practice regarding brain death. We aim to challenge the notion that the question has been definitively settled, despite the widespread application of this concept in medical practice including at Catholic facilities. We first summarize some of the notable arguments for and against brain death in Catholic thought as well as the available magisterial teachings on this topic. Although Catholic bishops, theologians, and ethicists have generally signaled at least tentative approval of the neurological criteria for the determination of death, we contend that no definitive magisterial teaching on brain death currently exists; therefore, Catholics are not currently bound to uphold any position on these criteria. In the second part of the article, we describe how Catholics, particularly Catholic medical practitioners, must presently inform their consciences on this issue while awaiting a more definitive magisterial resolution. Some prominent Catholic theologians and physicians have argued against the validity of brain death; however, most Catholic ethicists and physicians accept the validity of brain death as true human death. In this paper, we argue that there is no definitive magisterial teaching on brain death, meaning that Catholics are not bound to uphold any position on brain death. Catholics in general, but especially Catholic medical practitioners, should inform their consciences on this intra-Catholic debate on brain death while awaiting more definitive magisterial teaching.
