1 Corinthians 5:11-12

I meant that you are not to associate with anyone who claims to be a believer yet indulges in sexual sin, or is greedy, or worships idols, or is abusive, or is a drunkard, or cheats people. Don’t even eat with such people. It isn’t my responsibility to judge outsiders, but it certainly is your responsibility to judge those inside the church who are sinning.
