Commentary

This verse from the Apostle Paul's first letter to the Corinthians addresses a serious issue within the church community. Paul confronts their attitude regarding sin among them, specifically a case of severe immorality mentioned earlier in the chapter (see 1 Corinthians 5:1).

Context

The Corinthian church, despite having spiritual gifts, was struggling with various issues, including division, pride, and tolerance of sin. In chapter 5, Paul specifically tackles a case of incestuous relationship that was not only present but seemingly tolerated, or even ignored, by the congregation. Paul's statement, "Your glorying is not good," likely refers to their pride or complacency in their spiritual status, which blinded them to the need for dealing with this grave sin. Instead of grieving over the sin, they were boasting in other things.

Key Themes

  • The Danger of Complacency: The church's pride or indifference prevented them from addressing sin effectively.
  • The Pervasive Nature of Sin: Like leaven, sin has a way of spreading and corrupting the entire community if not dealt with.
  • Corporate Responsibility: The presence of unaddressed sin affects the spiritual health of the whole body of believers.
  • The Call to Purity: This verse serves as a warning and a call for the church to maintain spiritual purity by confronting sin.

Linguistic Insights

The word "leaven" translates the Greek word zymē (ζύμη). In Jewish culture and the New Testament, leaven is often used metaphorically to represent a corrupting influence, whether it be sin, wickedness, or false teaching (as also seen in Galatians 5:9). The phrase "leaveneth the whole lump" illustrates how a small amount of this corrupting agent can quickly permeate and change the entire batch of dough.

Reflection and Application

This verse is a timeless reminder for individuals and churches alike about the serious consequences of tolerating sin. Just as a little leaven affects the whole lump, allowing sin (whether individual or corporate) to go unchecked can undermine the spiritual vitality and witness of the entire community. It calls believers to vigilance, humility, and a commitment to addressing sin according to biblical principles, ensuring that the church remains a pure and effective witness for Christ (see the call to purge out the old leaven in the very next verse). True spiritual health requires confronting sin with seriousness and grace.
