Scripture:
Act 20:27 For I have not shunned to declare unto you all the counsel of God.
Act 20:28 Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
Jesus Christ is in 'charge' as He is the "Head", and He sent the Holy Ghost down to us, and thus He is in charge down here in Christ's stead. Yet, there is "order" in the "body" of Christ. This includes, Elders (Bishops/Overseers), Deacons, etc.
Eph 4:11 And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;
Eph 4:12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ:
Eph 4:13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ:
Eph 4:14 That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive;
Eph 4:15 But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:
Eph 4:16 From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.
There are undershepherds to Christ Jesus:
1Pe 5:2 Feed the flock of God which is among you, taking the oversight thereof, not by constraint, but willingly; not for filthy lucre, but of a ready mind;
1Pe 5:3 Neither as being lords over God's heritage, but being ensamples to the flock.
1Pe 5:4 And when the chief Shepherd shall appear, ye shall receive a crown of glory that fadeth not away.
Notice, there are those who 'rule' over (in the context of the church), as they have an appointed office from God:
Rom_11:13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
Rom_12:4 For as we have many members in one body, and all members have not the same office:
1Ti_3:1 This is a true saying, If a man desire the office of a bishop, he desireth a good work.
1Ti_3:10 And let these also first be proved; then let them use the office of a deacon, being found blameless.
1Ti_3:13 For they that have used the office of a deacon well purchase to themselves a good degree, and great boldness in the faith which is in Christ Jesus.
Act_6:3 Wherefore, brethren, look ye out among you seven men of honest report, full of the Holy Ghost and wisdom, whom we may appoint over this business.
1Co 9:12 If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ.
2Co 1:24 Not for that we have dominion over your faith, but are helpers of your joy: for by faith ye stand.
1Th_5:12 And we beseech you, brethren, to know them which labour among you, and are over you in the Lord, and admonish you;
Heb_13:7 Remember them which have the rule over you, who have spoken unto you the word of God: whose faith follow, considering the end of their conversation.
Heb_13:17 Obey them that have the rule over you, and submit yourselves: for they watch for your souls, as they that must give account, that they may do it with joy, and not with grief: for that is unprofitable for you.
Heb 13:24 Salute all them that have the rule over you, and all the saints. They of Italy salute you.
