摘要:In this work the author points to the emergence of bio-ethics as a new scientific discipline as a result of contemporary scientific progress, especially in medicine and biomedicine. As medicine was faced with ever more ethical dilemmas in clinical practice and in researches, the need was felt to form ethical commissions for ethics and for ethical activity and judgement. The author presents historical reference of the origin of ethical commissions, first in Canada and USA, then in Europe and with us. He points out that the Canadian bishops, led by the idea of the Second Vatican Council, gave impetus to the emergence of ethical commissions. In the second part the author makes reference to the European practice and considers it in our Croatian context as well, and warns that our practice has not reached the European yet, especially when talking about education and consulting. In the last part the author speaks about ethics in ethical commissions, emphasises some ethical principles of the Church and offers personalized ethical model as the only one worthy of man.
