How many churches follow 1st Corinthians 5:11?

That was church discipline and the church of today has gotten so far from scripture that many in the church are in danger of hell fire- as a matter fact if read farther about the immoral brother (sleeping with his fathers wife) they thought they were being open minded by allowing this - and Paul said to put him out of the fellowship of the church until he repents. The politically correct movement is not a new thing- it is the same old lies under a new name- immorality cannot and should no be tolerated within the community of believers - and it is today under the same pretense- of being tolerant and open minded. The church needs to get back to its roots and make it plain that if you are to follow Christ then openly sinning is not to be tolerated. That is why the church is losing its influence and voice in society- there is nothing anymore that sets us apart. We act and look and talk the same as the world does. These are the areas where people should look at say- what do they have that I don't? Why are they so different and have such joy? That joy can only come from being obedient to Christ.
