The first family was headed by Adam with his wife Eve. With their children, they made the first family. As the offspring married (they married siblings) they produced new families. Family, the “nuclear” family is a man and woman and the children they produce.
Merriam Webster defines it “the basic unit in society traditionally consisting of two parents rearing their children;” But to reflect the modern condition, Merriam Webster also includes family to be: any of various social units differing from but regarded as equivalent to the traditional family – a single-parent family”
Now, the modern “equivalent” family has a foundation of brokenness – the pieces cobbled together from pure and impure pieces. There is great pressure in society (felt even in public schools where a mural produced by a student depicting the “nuclear” family had to be removed because it would be insensitive to the children whose “families” fit the modern definition) to redefine family to mean gay and lesbian couples who get a hold of children through adoption or from previous heterosexual relationships one or both had. Next, and mark by words, family will be accepted as polygamist. “Threesomes” (3 females, for example) are already exerting pressure for society to be accepted.
The foundation of society must be the family as God designed it. The modern family definition begins with brokenness of marriage and home and commitment. This is not the way to build stable society. We need to preach marriage, permanent and committed, or we will be unfaithful to God and we will be participants in the malaise that’s unfolding before our eyes.
