When Leaving Is Faithful

Today's Reading

Read Galatians 1:6-9: "I am astonished that you are so quickly deserting him who called you in the grace of Christ and are turning to a different gospel — not that there is another one, but there are some who trouble you and want to distort the gospel of Christ. But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed."

Then Galatians 2:11-21 — Paul confronts Peter publicly at Antioch because Peter has begun, under social pressure, to act as if Gentile believers were second-class. "I opposed him to his face," Paul writes, "because he stood condemned." Add 2 Corinthians 11:3-4 ("if someone comes and proclaims another Jesus than the one we proclaimed... or a different gospel from the one you accepted, you put up with it readily enough") and Jude 3-4.

Reflection

Yesterday's chapter was 1 Corinthians 13, and the question was love. Today's chapter is Galatians 1, and the question is the gospel itself. Both questions are in the New Testament, written by the same apostle, addressed to churches he loved. They are not in tension. They are the two halves of a single discernment.

Paul's letter to the Galatians is, on the page, an act of horror. The word he uses for what has happened — metatithesthe, "you are turning, deserting" — is the word for a soldier abandoning his post. He does not write to the Galatians the way he writes to the Corinthians. He does not call them saints in the opening, does not thank God for them, does not ease into the rebuke. He moves straight from the greeting to: "I am astonished." The Corinthians are tearing each other apart over teachers and tongues, and Paul is grieved. The Galatians are accepting a different gospel, and Paul is on fire.

This is the category we cannot afford to lose. There is a kind of departure that is not betrayal. There is a kind of leaving that is faithful. There is a moment when staying would itself be a denial of Christ — not because the church has irritated us, but because the church has begun to preach another Jesus.

Notice how narrowly Paul defines that moment. In Galatians, the issue is not music, not leadership style, not the pastor's personality, not the congregation's politics, not even (precisely) ethics. The issue is whether sinners are justified by grace through faith in the crucified and risen Christ, or whether they must add the works of the law to be acceptable to God. That is the gospel itself — the difference between a Christianity that saves and a Christianity that does not. When that is at stake, Paul does not appeal for unity. He pronounces an anathema. "Let him be accursed." Twice, for emphasis.

The early church understood this category. When Arius taught in the fourth century that the Son was a created being — that "there was a time when the Son was not" — Athanasius, then a young deacon and later the bishop of Alexandria, refused to accept it as a permissible variation within the church. He went into exile five times rather than commune with bishops who endorsed Arian formulas. His enemies called him intransigent. His own letters call him grieved. But he saw, rightly, that if Jesus is not God, then no one has been saved by him, and a church that taught otherwise was no longer a church. The cost of his stand was decades of personal suffering. The benefit was that the Nicene faith — that the Son is homoousios, of one substance with the Father — survived. Athanasius did not split the church to indulge a preference. He stood against a church that had, in his judgment, departed from Christ himself.

Luther later inherited the same logic, though with different doctrine. So did Calvin. So, in another century, did Bonhoeffer. So did Spurgeon. None of them treated leaving as ordinary. Each treated it as the rare, grave, last resort when the gospel itself was at stake.

The temptation in our own moment is to expand the Galatians category until it covers anything we feel strongly about. Christians on every side of every cultural argument are tempted to claim that their contested concern is, in fact, the gospel — and therefore that everyone who disagrees is a Judaizer or a heretic and any departure is justified. This is how Galatians 1:8 gets weaponized in service of preferences Paul never imagined. We must read more carefully than that. The Galatian heresy was not a debate about how Christians should think about contemporary politics. It was a denial that Christ's death was sufficient to save without an additional human work. That is a small target, and Paul aims at it precisely.

But the target is there. The New Testament gives us no permission to absorb a different gospel for the sake of institutional unity. When the foundation has been replaced, the building does not still stand by some accident of having the same name on the door. Paul's word in Galatians is not "be tolerant of variation." It is "if anyone preaches a different gospel, let him be accursed."

How do you tell the difference, in your situation, between irritation and Galatians? A few honest tests, drawn from Paul's own letters:

First, ask whether the issue is Christ's person and work or something downstream. Galatians is about justification — about how a sinner is made right with God. If your issue is whether Jesus is fully God and fully man, whether he died for our sins and rose bodily, whether we are saved by grace alone through faith alone in Christ alone, you are in Paul's territory. If your issue is whether the church should sing fewer hymns or more hymns, you are not.

Second, ask whether mature, gospel-rooted believers in other settings would recognize the issue as gospel-defining. Paul did not invent the Galatians' gospel. He had received it. The category of "gospel itself" is a public category, not a private one. If only you and a small group of intense friends see the church as having lost the gospel, that is data — not necessarily decisive, but data.

Third, ask whether you have done what Paul did at Antioch. He did not leave. He confronted Peter, publicly and clearly. The Galatians 2 pattern is: name the failure, name it to the face of the person responsible, do it in front of the church, and only then — if no repentance follows — consider the next step. Most modern leaving skips the confrontation altogether. We slip out the back instead.

The narrow door of faithful leaving exists. The mistake is to treat it as wide.

Going Deeper

Read Galatians 2:11-14 once more, slowly. Paul's confrontation with Peter is striking for what it is not. It is not a denominational split. It is not Paul founding a rival apostolic college. It is one apostle, in love and grief, publicly correcting another for behavior that contradicted the gospel — and Peter, by every indication, received it. The two of them were still brothers afterwards.

Most of what we now call "having to leave" is actually the absence of any willingness to stay long enough for the Galatians 2 conversation to happen. Before you walk out the door over the gospel, ask whether you have walked into the office over the gospel. The answer to that question changes the meaning of every step that follows.
