Through the analysis of some main bioethical documents, the work points out on the moral problems related to Man’s pretence to assume the role of creator of new life. According to the new biotechnological achievements, man has touched his own life, which is most sacred for the theology and that for, the bioethical speech has to permeate the theology and in their interdisciplinary they both has the sacred duty to speaks with awe, to teaches and to watch over each newly created human being, trying to protect it.
