Family relationships are becoming increasingly complex. We no longer speak of only one type of union between people - man and woman - and marital arrangements are easily unraveled. How do these changes affect the social values and cultures we reproduce? Controversies and new perspectives are the focus of this book, which brings together renowned Latin American doctrinal voices. The four studies gathered here form a discursive order outlined in the three national realities examined - Peruvian, Colombian and Brazilian. An invitation to think about lives built in bed.
