What Is the Family?
The Bible defines "family" in a narrow sense as the union of one man and one woman in matrimony which is normally blessed with one or several natural or adopted children. In a broad sense, this family also includes any other persons related by blood (the extended family). In the book of Genesis, we read that God in the beginning created first a man (Adam) to exercise dominion over his creation and subsequently a woman (Eve) as the man's "suitable helper" (Genesis 2:18, 20). Then, the inspired writer remarks, "Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh" (Genesis 2:24 ESV). This verse sets forth the biblical pattern as it was instituted by God at the beginning: one man is united to one woman in matrimony, and the two form one new natural family.
