Read: Acts 20:13-38
Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. Acts 20:28
The primary responsibility of an elder or pastor is to teach the Scriptures, to feed the flock. If he is not doing that, he is failing in his job, miserably. It is the truth that changes people. If the Scriptures are not being taught then people are not being changed. They are struggling in their own futile ways and nothing is being accomplished. So the primary job of elders and pastors is to set the whole counsel of God before the people.
They are to begin with themselves, says the apostle, i.e., they are to obey the truth which they themselves learn. This is where their authority comes from. It is only as they are obedient to the truth which they teach that they have any right to say anything to anyone else. Even the Lord Jesus operated on that basis. He said to his disciples on one occasion, If I do not do the works of my Father, do not believe me… (John 10:37). That is, if what I am doing is not in exact accord with what I am saying, then don’t believe me!
Would you dare say that to your children? Or to your Sunday school class? Or to others who observe you as a Christian? If what I am doing is not in line with what I teach, then don’t believe me. I have no authority over you; I have no power over you. But if your actions are in accord with your teaching then power is inherent in that obedience.
So these pastors and elders are to begin with themselves, and to teach the Word. Their responsibility is to the Holy Spirit, not to the denomination, nor to the congregation. It is the Spirit who has set them in that office and has equipped them with gifts. He who reads the heart is judging their lives, so it does not make any difference what anybody else thinks. They are responsible to follow the Holy Spirit in what he has given them to do.
