Germ-line gene therapy, like many other medical technologies, raises questions of special concern to Christians. It not only raises questions about medical effects, actual or possible, of genetic interventions that would be inherited from one generation to another but also, more importantly, raises anthropological questions and so questions about parental attitudes. These are questions about the dignity and value of human life, about inter-human relations and about the God-human relationship.1 For this reason the paper starts with an exploration of the (...) implications of Christian anthropology, viewed from a Roman Catholic perspective. A set of conditions will be specified in the light of which germ-line gene therapy’s compatibility with Christian attitudes, a Christian understanding of the human being, and the meaning of human life can be assessed.
