Family: a group united by marriage, or cohabitation, blood, and/or adoption in order to satisfy intimacy needs and/or bear and socialize children.
Culture: Attitudes, behaviors, arts, beliefs, and values pertaining to a specific social group.
Social Class: a division of a society based on social and economic status.
You personal culture mainly comes from family experiences. Think about your traditions. Where did they come from? They probably came from your ancestors. For example, Christmas meals in my family are the same every year because we like to carry on that tradition from generation to generation.
All cultures are different because everyone has their own way of living. However, that does not mean that one culture is right or wrong. Everyone has the agency to live the way they want. Cultures will clash and some cultures will adapt to new ways of life. The most important thing to keep in mind when you are creating a new family culture is to keep it in line with Heavenly Father's plan. Our ultimate goal in this life as Latter-Day Saints is to return back to our Father in Heaven. We do this by following the commandments that have been placed before us from Heaven. Elder Oaks has said: “This gospel culture comes from the plan of salvation, the commandments of God, and the teachings of the living prophets. To help its members all over the world, the Church teaches us to give up any personal or family traditions or practices that are contrary to this gospel culture.”
Another contributor to family life is social class. Some factors of social class include, money, ancestry, behavior, confidence, education, speech, location, dress, etc. People judge others with these factors and most of the time look down or look up to others, comparing who is better. But we need to keep in mind that perceptions are not always reality. We may all look different, but we are spirit sons and daughters of Heavenly parents who love us no matter what!
