Abstract
With this power to edit our own genes comes the enormous responsibility to determine if, when, how, and why we should, or should not, employ this technology. This article addresses this responsibility from the perspective of the moral tradition and reasoning of the Catholic Church. Past, present, and possible future positions of the Catholic Church regarding human genome manipulation are analyzed in light of the fundamental values that undergird Catholic ethical reasoning, and the significant contributions the Catholic perspective can bring to global deliberations on the responsible use of human genome editing are identified. These contributions represent both opportunities and obligations for the Catholic Church in its continuing tradition of providing health care around the world, especially to those who are the most vulnerable and most in need.
