This part matters because leaders without authority cannot lead, and leaders without accountability become dangerous. The New Testament gives both, and holds them together. It also gives the church a way to deal with sin, in leaders and members alike, that is neither soft nor cruel.
The real authority of elders
Elders have real authority, given by Christ. "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" (Hebrews 13:17). The words "have the rule" translate hegeomai (G2233), "to lead ... (with official authority)". "Submit" is hupeiko (G5226), "to surrender".
Paul asks the Thessalonians "to know them which labour among you, and are over you in the Lord, and admonish you; And to esteem them very highly in love for their work's sake" (1 Thessalonians 5:12-13). "Are over you" is proistemi again, the word for ruling a household well.
And elders who rule well, especially those who labour in preaching and teaching, are "counted worthy of double honour" (1 Timothy 5:17) — honour that, as the next verse shows, includes material support: "Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward."
So the church is to know its leaders, love them, esteem them, follow them, support them and make their work a joy rather than a grief. Many churches fail here as badly as some leaders fail in the other direction.
The limits of their authority
But the same texts set firm limits.
It is authority under Christ. Elders are stewards, not owners. They "watch for your souls, as they that must give account" (Hebrews 13:17). The flock is "the flock of God" (1 Peter 5:2).
It is authority over the church's life, not over the conscience. Paul, an apostle, wrote, "Not for that we have dominion over your faith, but are helpers of your joy: for by faith ye stand" (2 Corinthians 1:24). Elders teach, guard and correct according to Scripture. They do not invent new rules for their people's private lives or bind consciences where God has not.
It is authority without domination. "Neither as being lords over God's heritage, but being ensamples to the flock" (1 Peter 5:3). Jesus' word to the disciples governs every church leader: "so shall it not be among you" (Mark 10:43). The companion paper Biblical Leadership develops this at length.
It is authority bounded by the word. When leaders teach what is contrary to Scripture, the believer's first obligation is to God. The Bereans were praised because they "searched the scriptures daily, whether those things were so" (Acts 17:11) — even when the teacher was Paul.
John's warning about Diotrephes "who loveth to have the preeminence among them" (3 John 1:9) shows what happens when these limits are ignored: a leader who gossips against true servants of God, refuses hospitality, and casts people out of the church to protect his own position.
Accountability for leaders
Paul gave Timothy specific instructions for handling accusations against elders:
"Against an elder receive not an accusation, but before two or three witnesses. Them that sin rebuke before all, that others also may fear. I charge thee before God, and the Lord Jesus Christ, and the elect angels, that thou observe these things without preferring one before another, doing nothing by partiality." (1 Timothy 5:19-21)
Protection from slander. Leaders are exposed to complaint and rumour. An accusation is not to be entertained without two or three witnesses — the standard of the law (Deuteronomy 19:15) and of Jesus (Matthew 18:16). This protects faithful leaders from being destroyed by gossip.
No cover-up. But when sin is established, "Them that sin rebuke before all, that others also may fear." A leader's sin, especially when it touches his office, is to be dealt with openly. The temptation in many churches is to handle a leader's sin quietly, to protect the ministry's reputation. Paul forbids it. The leader's position makes the public correction more necessary, not less.
No favouritism. "Without preferring one before another, doing nothing by partiality." A popular or gifted leader is not to be treated more gently than an obscure one. Paul's charge is made "before God, and the Lord Jesus Christ, and the elect angels" — the whole court of heaven is watching how the church handles its leaders.
Accountability with money
Paul took remarkable care over money. When he collected relief funds for the poor in Jerusalem, he arranged for representatives of the churches to travel with the gift, explaining: "Avoiding this, that no man should blame us in this abundance which is administered by us: Providing for honest things, not only in the sight of the Lord, but also in the sight of men" (2 Corinthians 8:20-21).
"Not only in the sight of the Lord, but also in the sight of men." It is not enough for leaders to be honest; their handling of money must be seen to be honest. In practice that means at least two unrelated people counting and recording offerings, clear records open to the church's appointed overseers, and no leader having sole, unchecked control of the church's money. These are not signs of distrust. They are Paul's own practice, and they protect the leaders as much as the church.
Church discipline
Discipline is one of the most neglected duties of church leadership, and one of the most misused. Scripture gives a clear path.
Begin privately. The Lord Jesus gave the steps:
"Moreover if thy brother shall trespass against thee, go and tell him his fault between thee and him alone: if he shall hear thee, thou hast gained thy brother. But if he will not hear thee, then take with thee one or two more, that in the mouth of two or three witnesses every word may be established. And if he shall neglect to hear them, tell it unto the church: but if he neglect to hear the church, let him be unto thee as an heathen man and a publican." (Matthew 18:15-17)
The aim at each step is to "gain thy brother". Most matters should end at the first step. Only persistent, unrepentant sin moves on.
Act on public, serious sin. In Corinth a man was living with his father's wife, and the church was proud of its tolerance. Paul was severe: "ye are puffed up, and have not rather mourned, that he that hath done this deed might be taken away from among you" (1 Corinthians 5:2). The church was to act "when ye are gathered together ... with the power of our Lord Jesus Christ, To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus" (1 Corinthians 5:4-5). Even this most serious step aimed at the man's salvation. Paul names the kind of open, unrepentant sin that requires it: "if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner" (1 Corinthians 5:11). And he limits it to those within: "For what have I to do to judge them also that are without? do not ye judge them that are within?" (1 Corinthians 5:12).
Deal firmly with divisive teachers. "A man that is an heretick after the first and second admonition reject" (Titus 3:10). False teaching that divides the church is to be confronted, warned twice, and then refused.
Never treat the disciplined as an enemy. "And if any man obey not our word by this epistle, note that man, and have no company with him, that he may be ashamed. Yet count him not as an enemy, but admonish him as a brother" (2 Thessalonians 3:14-15).
Restore the repentant fully. It appears that the Corinthian church eventually acted, and the man repented. Paul's second letter tells them to stop: "Sufficient to such a man is this punishment, which was inflicted of many. So that contrariwise ye ought rather to forgive him, and comfort him, lest perhaps such a one should be swallowed up with overmuch sorrow. Wherefore I beseech you that ye would confirm your love toward him" (2 Corinthians 2:6-8). Discipline that never ends in restoration has forgotten its purpose.
Restore gently. "Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted" (Galatians 6:1).
The whole process belongs to the church, led by its elders. It is not the private weapon of a pastor against his critics, and it is not a public spectacle. It is the church obeying Christ, for the good of the sinner, the purity of the body and the honour of the Lord's name.
Leaders who fall
When an elder or deacon falls into serious sin, the texts above apply with added weight. The accusation must be established by witnesses. The sin must be rebuked before all. The leader, if he repents, is to be forgiven and restored to fellowship with full love. Whether and when he may serve in office again is a separate question, and churches differ on it. But the qualification "blameless" is a present requirement: an elder whose life is under an open, recent charge is not presently qualified, however sincere his repentance. Forgiveness is immediate; trust is rebuilt over time. A church that confuses the two will either crush the repentant or endanger the flock.
