The Family: A Proclamation to the World was given to the LDS members in 1995 as a guide to the family unit. This is the official position of the Mormon church on the family, marriage, and gender roles. These teachings have been given to the Saints throughout the church's history, but here it can all be found in one place.
I believe the family is one of the most important responsibilities we have in this life. God placed us in family units to learn, grow, and love. Unfortunately, the sacredness of the family is being neglected by many people these days. This is a tool of the adversary. I really believe that the breakdown of the family is one the biggest problems in our society today. If we all had strong families, I believe there would be much less violence, poverty, disease, poor education, maybe even global warming (haha, ok, maybe not that). But what I'm trying to say is that the breakdown of the family lies at the core of a lot of the issues our society faces.
If you read this proclamation you will see that it refers mainly to the traditional family of a mom and a dad with children. I understand that because of death and other reasons beyond our control, this "traditional" family may not be possible. The proclamation states "Disability, death or other circumstances may necessitate individual adaptation." A single parent may be raising the children, or even a grandparent; but the message still applies that a family should consist of love and righteousness.
If you are not familiar with this statement, READ IT! If you are familiar with it READ IT AGAIN! It really is beautiful.
