1 Corinthians 5:6b-8: Get Rid of Bad Leaven!

September 24, 2026 Blaize

Paul's concern over an individual in Corinth involved in an immoral relationship leads him to discuss the necessity of removing such individuals from the church. He employs the metaphor of leaven, which the New Testament uses in various contexts. In Matthew 13:33 and Luke 13:20-21, leaven represents the expansive growth of the Kingdom of Heaven. Conversely, in passages like Matthew 16:6-12 and its parallels in Mark 8:15-21 and Luke 12:1, Jesus warns His disciples about the "leaven of the Pharisees and Sadducees", alluding to the corrupting influence of their teachings. Similarly, in Galatians 5:9, Paul highlights how a small amount of false teaching can sway a larger group. This theme illustrates how a minor element, analogous to leaven, can profoundly influence a broader context. In 1 Corinthians, echoing sentiments from Galatians, Paul addresses a specific sin, stressing that individual transgressions shouldn't contaminate the entire church in the way that leaven causes the entire loaf to rise. Titus 3:10-11 underscores the prudence of distancing oneself from divisive members after initial warnings. 2 Thessalonians 3:6-15 further reinforces the concept of collective protection, where Paul delves into the issue of idleness within the church, suggesting a tactful distance from such individuals yet retaining a compassionate, corrective stance.

Sin should be taken seriously, but expulsion from a congregation should be a last resort. Churches are ideally oriented toward reconciliation as an initial response to sin. This commitment to maintaining a community's sanctity is evident in Jesus' guidance in Matthew 18:15-20. The steps he proposes are:

Approach the person privately to discuss their actions.

If unheeded, involve one or two others.

If the person remains defiant, present the issue before the entire congregation.

If they still disregard the church's concerns, they should be considered outsiders.

Emphasizing reconciliation, the New Testament consistently promotes correction over punishment. While Galatians 6:1 encourages gentle rectification, more extreme cases, like the one mentioned in 1 Timothy 1:20, have Paul hinting at excommunication, but with the end goal of repentance and reconciliation. In essence, the New Testament's doctrine on church discipline harmonizes the dual objectives of safeguarding the community's spiritual well-being and redeeming the errant, all the while preserving reverence for Christ and the sanctity of the gospel.

Applying Jesus' teachings offers invaluable insights for contemporary churches. While church discipline is challenging, reconciliation remains paramount. If repentance is absent, there may arise a necessity to separate from the errant individual. This separation isn't limited to sinful actions but can extend to doctrinal disagreements. In Western contexts, the efficacy of church discipline may appear diminished, as individuals can easily find congregations that condone their choices. However, it's vital to recall that church discipline serves dual purposes: addressing transgressions and safeguarding the local congregation. In all endeavors, the overarching aim should always be grace, with a fervent hope for restoration. In doing so, the church can "celebrate the feast," namely the Passover where God covers sin, with the "unleavened bread of sincerity and truth."

Lord, help me reconcile those who will and separate from the won't!
