Myth: Someone in authority should never teach those under them to obey their authority.
Truth: Titus 2: 15 These things speak and exhort and reprove with all authority. Let no one disregard you.
You cannot read a letter by the Apostle Paul without him defending and maintaining his authority as an apostle. He does it over and over again. And then he instructs Titus and Timothy to do it with their authority.
Sometimes those in authority have to defend their authority and they do so with scripture. A faithful husband will wash his wife in the word. This will include teaching his wife about authority and submission. It will sometimes mean defending his authority in the home.
Exercising authority is not the same thing as lording it over. Husbands exercise authority for the benefit of those under his charge, for the benefit of the whole family. Sometimes that means they will instruct on things they personally may benefit from. This does not mean that they should abuse their authority and use it primarily for their own benefit.
Parents will instruct their children to obey them. This constitutes a whole lot of the instruction of parents. Parents who refuse to do this are being unfaithful.
The same thing with pastors. Pastors often have to instruct their people on submitting to pastors and to paying tithes, things he benefits from but he does it because he is being faith to God and is looking for the benefit of God's church.
