1 Corinthians 5:6-7
Your boasting is not good. Do you not know that a little leaven leavens the whole lump? Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our Passover lamb, has been sacrificed.

Paul’s reminder about leaven isn't just about sin spreading; it’s about how easily a single instance of unaddressed sin can corrupt the entire community, making them unaware of their compromised state. The "little" leaven highlights the deceptive nature of sin – it often starts small but has the power to ruin everything if left unchecked.
Paul is addressing a serious issue of sexual immorality within the Corinthian church, specifically a man openly living with his stepmother. He's directly confronting their pride and lack of discernment in tolerating such a sin, warning them that their unaddressed corruption will spread and affect the entire community if left unchecked. This verse sets the stage for Paul's clear instructions on how to deal with the unrepentant sinner through community discipline.
Paul starts this letter with a strong rebuke. He calls out the church's pride, not for something flashy, but for something seemingly small. What's the big deal about boasting?
The Danger of Pride
Paul doesn't mince words: "Your boasting is not good." In the context of 1 Corinthians, the church was boasting about their spiritual prowess, their wisdom, and even their tolerance of a deeply immoral member (as seen in the verses leading up to this). This pride was not harmless; it was actively damaging their spiritual health.
Think about it like this: when we're proud of our own accomplishments or our group's 'wisdom,' we can become blind to our own flaws and the real issues at hand. This self-congratulation can create a distorted reality, making us less sensitive to sin and more susceptible to its spread.
The image of 'leaven' is powerful and unsettling. It's small, easily hidden, but incredibly potent. What does this ancient baking ingredient reveal about sin's impact?

In Jewish tradition, leaven (or yeast) was often associated with sin and corruption. A tiny bit, mixed into a large batch of dough, would permeate the entire lump, causing it to rise and change. Paul uses this vivid metaphor to illustrate how sin, especially when tolerated and even celebrated, spreads throughout a community.
Paul is warning the Corinthians that their tolerance of this one significant sin is not an isolated incident. It's 'leavening' their entire church culture, making them spiritually unhealthy and compromising their witness.
