A good Christian family is one that lines up with biblical principles and one in which each member understands and fulfills his or her God-given role. The family is not an institution designed by man. It was created by God for the benefit of man, and man has been given stewardship over it. The basic biblical family unit is comprised of one man, one woman—his spouse—and their offspring or adopted children. The extended family can include relatives by blood or marriage such as grandparents, nieces, nephews, cousins, aunts, and uncles.
