Words of Wisdom from my Brother

So, my brother has this saying.  It goes something like this, "there is a reason that it is a stereotype," meaning basically that if there is a stereotype there may be some kernel of truth behind it.  He always says it half jokingly...but only half.  I found myself thinking about that saying this morning after reading some scripture.
There is a stereotype about the church that it is full of hypocrites and that it does not practice what it preaches.  It is perhaps, the number one complaint leveled against the church form those on the outside looking in.  I am sure that like every stereotype, in many cases the accusations are less then honest, based on far less than fact or experience and are just that, stereotype.  But then the question arises...is there a reason that it is a stereotype?  Could there be a kernel of truth in the sentiment?  I am asking that question again today after reading Matthew chapter 23.   Jesus is teaching his disciples and the crowds when he states:

"The teachers of the law and the Pharisees sit in Moses' seat.  So you must obey them and do everything they tell you.  But do not do what they do, for they do not practice what they preach..."   

 - Matthew 23:2-3

Here was Jesus, two thousand years ago or so, speaking about the religious establishment and leadership of the day and criticizing them for being hypocrites and not practicing what they preach.  Is that same dynamic at work today when we look at the church?  Is there something about the religious establishment that leads towards hypocrisy?  So the question I am asking today is, is there is something to this stereotype?
