cliques in churches

I,ve been aware for too long the backbiting etc that goes on in parish churches.I used to bury my head and try and be pleasant to all,even the vicar! Over the past year ,ive found myself drawn into gossip, which i feel really bad about, so much so that ive decided to leave christianity for good. someone reminded me recently ,'lots of peple go to church, but there aint many christians there' I guess that ive been naive to think that people can behave like christians while in church,even just for an hour a week.It does sadden me ,but i'm going onwards with a faith in myself and also a vague sense in goodness both within and without, thanks for reading my rant!
