Be not deceived: evil communications corrupt good manners.
Paul is quoting a well-known Greek proverb from the playwright Menander, showing his culturally savvy audience that even pagan wisdom recognized this truth. He's warning the Corinthian church that moral character is more fragile than we think. "Company" isn't just close friends — it's anyone whose values and behaviors influence you over time. Paul uses the perfect tense in Greek, suggesting this corruption process is already complete, not hypothetical.
God, give me eyes to see how my relationships are shaping me. Help me choose the company that makes me more like You, and wisdom to know when to stay and when to step back. Keep my character aligned with Yours. Amen.
You felt it happening during that group chat where cynicism replaced hope, or that job where everyone cut corners so gradually you barely noticed your own. Character isn't eroded by dramatic betrayals; it's sanded smooth by daily exposure to attitudes that don't match who you claim to be. The scary part? You probably won't feel the shift. Like catching a cold, you'll think you're fine until you hear yourself saying things your grandmother would have slapped you for. This isn't about paranoid friend-purging; it's about honest assessment. Who are you becoming in each relationship? Take inventory this week: which conversations leave you more cynical, more cruel, more numb — and which leave you more like Jesus? The answer will tell you where your character is headed.
