1 Corinthians 5

http://www.esvbible.org/1+Corinthians+5/

Paul condemns the church for sexual sins that some of the members have committed. One of the main problems, besides the fact that they are choosing to live a life of nothing but sinning and that is not how we are called to live, is that the world is always watching the church, waiting for it to mess up, so we shouldn't give the world any evidence to use against us. Paul says that those who cause the problem must change or the church needs to remove those members until they clean up their acts. Paul says that he previously told the church not to associate with those who committed sexual sins, curse, get drunk or worship false gods, but he says he was not talking about non-believers because then there would be no one left. He says he was only talking about believers who do such things because they are false in their ways, and they aim only to bring down the church.
