In "Doctrinal Discussion" Jason Lindahl writes:

In fact, progressive society now tells us that the basic parts of a family machine are no longer necessary for it to run smoothly. Instead of parts A and B, we can substitute two A parts or two B parts and everything will work just fine. Satan can and will twist and distort anything and everything good which God has designed and created, but he cannot destroy the original blueprint. Have you ever used a machine or device for which you did not have the instruction manual, and while you could get it to function to some degree, you could just tell something wasn't right? The machine didn't seem to be working as efficiently as it should, and there were sections or parts that didn't seem to be useful for anything but must be designed for something. In the same way, in spite of all of society's confident insistence that the family can be anything we want it to be, there is a nagging reminder that Somebody designed this relationship, and it will never function properly except in the way fashioned by the Designer.

In "God's Word for Today" Gordon Snider writes:

“Dysfunctional family” is a common term these days. Psychology Dictionary defines that term as “a family showing impaired communication and relationships where members are unable to get close.” There may be a tendency to think of such a family as including divorced parents, alcohol or some other substance abuse, and/or moral failure. But by definition, a family may be dysfunctional where none of these components exist. It just means that a family is not close enough to communicate or feel connected on a meaningful level. God created the family to be a tightly knit unit where life's deepest emotional needs could be met. Yet many Christian families fail to operate with this degree of intimacy among its members: Obedience is compelled but not inspired; respect is demanded, but loving consideration is not shown; love is based upon things given instead of communication shared. To get back to God's intention for the family, the Christian home should follow God's relational principles.
