Any group of Christians, asked whether the church should practice mutual correction, will say yes. Speaking the truth in love (Ephesians 4:15). Faithful are the wounds of a friend (Proverbs 27:6). Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one (Galatians 6:1). Everyone agrees.

Then ask them when they last corrected anyone, or were corrected. The silence that follows is the finding.

Though Scripture commands it and everyone affirms it, mutual correction is almost never practiced. Cowardice is the easy explanation, but the conditions under which correction is safe have been removed from the form of the church, and no amount of exhortation restores them.

What love costs at three levels

Sort the one-anothers by what they cost.

Some cost nothing, such as greet one another and be kindly affectioned one to another, while others cost resources, as with bear ye one another's burdens and distributing to the necessity of saints. And some cost standing: admonish one another, confess your faults one to another, speaking the truth in love.

The third category is where obedience collapses. To admonish someone is to risk their goodwill, to confess a fault is to risk your reputation, and to disagree with a leader is to risk your place. People will only put their standing in the group at hazard, as these commands require, if they have reason to believe the group won't punish them for it.

That belief is called psychological safety. It is the single best-documented predictor of whether groups surface their own problems. Where it's present, people report errors, disagree with authority, and raise concerns. Where it's absent they don't, and the group's leaders conclude from the silence that nothing is wrong. The most striking finding in this research is that the best-functioning teams report more errors than poorly-functioning ones. They don't make more of them, but their members can say so.

A congregation with no reported problems may be a congregation in which problems can't be reported. The two are indistinguishable from the leader's chair.

Why people stay silent

The silence is less a flaw of character than a rational choice.

In a group where standing is scarce and unevenly distributed, speaking up carries a real cost and no protection. People hedge. They hint. They raise concerns obliquely, in language designed not to challenge, and the hint doesn't land because it wasn't built to. Research on why people fail to speak in organizations finds the same beliefs everywhere: it is not my place, nothing will change, I will be seen as a troublemaker, the leader doesn't want to hear it. Every one of those is a prediction about consequences, and in most congregations the prediction is correct.

Another finding explains why an entire congregation can be privately uneasy and publicly content. When individuals each believe they're the only one who sees the problem, they say nothing, and their silence confirms everyone else's belief that they're alone. The group's public consensus can be the exact opposite of every member's private opinion. It's called pluralistic ignorance. John describes it exactly.

Nevertheless among the chief rulers also many believed on him; but because of the Pharisees they did not confess him, lest they should be put out of the synagogue: for they loved the praise of men more than the praise of God. (John 12:42-43)

Many believed in private. They did not confess in public. The honour ranking did the silencing. Each ruler assumed he was alone.

Matthew 18 is a safety protocol

Read Jesus's instruction on correction with this in mind.

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. (Matthew 18:15-17)

The procedure has three stages. The first is between thee and him alone. Keeping it private protects the corrected person from public shame and protects the correcting person from public exposure if they're wrong. The second brings one or two more as witnesses, which protects both parties from the distortions of a private account. The third stage, the church, comes only after two failures, when the matter goes to the body instead of to an official.

It is a graduated procedure that keeps the cost of speaking low at every step, so correction is survivable for both sides. The person correcting doesn't have to stake their whole standing on the first conversation, and the person corrected doesn't lose face unless they refuse twice.

Galatians 6:1 adds the posture: restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted. The corrector goes in as a fellow sinner. That lowers the cost too, both for the corrected person, who isn't being condescended to, and for the corrector, who isn't claiming a standing they don't have.

Besides commanding correction, Jesus and Paul designed the conditions under which it could happen.

What the modern form removes

Every element of the protocol assumes something about the group.

Between thee and him alone assumes you know the brother well enough to go to him. In a congregation of hundreds, most members don't have that relationship with most others.

Take with thee one or two more assumes there are mutual friends who know both of you and can be trusted by both. That requires a network of overlapping relationships, the kind a household has and an audience doesn't.

Tell it unto the church assumes a body small enough to hear it and known enough to weigh it. It doesn't say tell it to the pastor.

And the whole procedure assumes that correcting someone is normal, something that happens often enough that nobody is astonished by it. Where correction is rare, nobody has the first conversation, because it would be a crisis.

The form of the modern church removes the relationships, the mutual friends, the small body, and the normalcy. What remains is the command, which everyone affirms and no one obeys.

The assembly that weighs

One more mechanism in the design protects a congregation from its leaders' errors.

Let the prophets speak two or three, and let the other judge. (1 Corinthians 14:29)

The assembly weighs what it's taught. For that to work, the hearers need enough standing to judge, and the speakers can't have been placed beyond judgment. In the design, teaching is checked by the body. In the modern form, teaching descends from a platform to an audience that has no mechanism for responding, and a leader can be wrong for years without anyone able to say so.

Timothy is told to receive accusations against elders, with safeguards (1 Timothy 5:19), and the Bereans are commended for checking Paul against Scripture (Acts 17:11). Paul rebuked Peter to the face (Galatians 2:11). The design assumes leaders will be corrected and builds the channel.

Recovering the conditions

Correction is recovered by rebuilding its conditions, which preaching about it cannot do. That means a body small enough to know each other, relationships dense enough to supply witnesses, the honour inversion operating so that standing isn't scarce, and a normalcy of small corrections that makes the large ones possible.

Start in the smallest unit, with two or three believers who have agreed, explicitly, that they will tell each other the truth and that the telling won't cost the relationship. Practice it on small things. When someone speaks up, thank them publicly and specifically. Over months the group learns that speaking is safe, until speaking becomes normal.

What looks like a technique is Matthew 18, built back one relationship at a time. A congregation full of such units can hear itself, and only a congregation that can hear itself can be corrected before it's too late.
