Streszczenie:
In this study advances the Author a thorough overview of Pius XII’s moral teaching on fields of ethics of situation, human dignity, the right to the life and importance of marriage and family. He shows Pope’s reactions to the results of modern sciences to be highly up-todate, especially on the field of medical science, and points his statements to problems as particularly well-founded. Pius XII had laid on the foundation of Church moral teaching so far applicable and attestable on the field of transplantation of organs, handling with cadaver, artificial maintaining of life, euthanasia etc. In his teaching about the sense of marriage and family Pope holds an opinion rather traditional, nevertheless the principles of personalistic perceiving of problem are more and more diffusing into his speeches.
