The Right Thing

In my short time, I have seen alot of wrong in the church. I am not one to judge others actions, but I do believe that some of these things aren't necessarily right.For instance, there is a church, where when many people drive by, quite more than often, they see one or two teenage couples on the churches front porch with their hands on each other. Hands on hips and backsides, lips pressed against one another's and on the other's necks and something that is simply repulsive to see in front of a church building. The girls are dressed scantily and their "boyfriends" don't seem to mind.It has been said that in this church, this is only one of the large problems with these couples. The girls ar said to be wearing attire that makes their chest and legs quite visible. And the boys of wearing street clothing to services.It is to the point where there are parents, patrons and elders, not letting their young children, both boys and girls, come to church. They are not allowed to attend Sunday School, Sunday's or Wednesday services, even Youth Choir Practices. In the Bible, it says that the church must take care of it's own. It is Biblical that if a disruption or uprising in the church, it is the churches reponsibility to take it out. It may be Biblical, but it sure won't be easy. So how does someone go about this? Should you take time to see if it changes?What happens when they say "Well, they need to be led to Christ? They need to stay in church!"? How do you do what is so difficult, but it is said that it has to be done in the Word?
