If you grant someone authority that they should not have, do not be surprised when they abuse that authority.

For example, the rightful place of authority in a family rests with the parents (especially the father).  If you join a commune and give another man the right to decide what is best for your family, do not be surprised when that man abuses your child or sleeps with your wife.  It is harder for the victims to defend themselves when they have already given over authority to the wrong person.  It is easier for the perpetrator to abuse his authority when he has already assumed authority that should not belong to him.  The lines have already been blurred.

The rightful place of authority in a local church rests in a plurality of elders who satisfy the requirements given in Scripture.  If a church gives all the authority to one man, do not be surprised when he misuses funds, engages in nepotism, and sleeps with someone he is supposed to be counseling.  If a church gives the authority to a board selected for their business acumen and popularity, do not be surprised when they bicker and divide the church into factions.  If a church hands over authority to the civil government, do not be surprised when the government says the church can no longer follow the mandates of Scripture.

In the public square, it is the role of government to punish wrongdoing.  Hand that authority over to the people, and you get lynch mobs and vigilantes.

Of course, this does not mean that those in places of improper authority will always abuse that authority.  Neither does it mean that those who are given authority properly will not succumb to sin and misuse their authority.  One does not cause the other, and there are other causes for the same effects.  It also does not mean that authority cannot sometimes be properly delegated to someone who would not normally wield that authority.  However, delegation of authority should be done carefully, with limited scope and well-defined boundaries.
