1Co_5:9 When I wrote to you before, I told you not to associate with people who indulge in sexual sin.
1Co_5:11 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.
No one preaches that anymore.... That would be a certain percentage of church goers we shouldn't associate with....
