Abstract
This essay responds to an article by Elizabeth Bothamley Rex titled “The Magisterial Liceity of Embryo Adoption”, specifically to Rex’s critique that his objections to the liceity of embryo transfer distort magisterial documents. He then draws out the implications of the differences between his view and Rex’s on the relation between maternity and pregnancy. The essay concludes by pointing out that, if they are to change their minds, opponents of embryo adoption need to be convinced that it is morally licit to impregnate, or “introduce an order to birth,” in a woman by means other than the marriage act.
