"“In carrying out research and treatment of human (or nonhuman) diseases, it is immoral to use embryonic and fetal tissue obtained from intentionally induced abortions. A major reason for opposing use of such tissue is that this is a form of complicity in moral evil,” William E. May, Testimony before the NIH Human Embryo Research Panel, February 2, 1994. See the comments of Albert S. Moraczewski, O.P., quoted in note 18 above.
