As Dr. Ilona Grądzka writes in his expertise, nowadays the primacy of man as a free being. On the other hand, the value of relationships between people is also emphasized. A special role in this area is attributed to the institution of marriage and the family created on its foundations. The moment of marriage is associated with the fact that we cease to be a unit and become part of a specific family.
