In 1 Corinthians 5 Paul calls the Corinthian church to remember their identity as God's holy people. He rebukes them not just for tolerating serious sexual sin within their community, but for being proud of their tolerance. Paul urges them to remove the unrepentant sinner to protect the church’s holiness, using the image of yeast spreading through dough. Just as God rescued Israel from Egypt, Christ, our Passover Lamb, has rescued us—so we are called to live in sincerity and truth, not in sin. Holiness matters, but so does grace, repentance, and heart-level devotion to Jesus.
