Church and mission 11/2-Voluntary commitment vs passive Christianity

Many orthodox churches are tied to a nation state. This makes Christianity a matter of passive acceptance and not a voluntary commitment. Most who are born in these nations believe that because I am a citizen of this country therefore I am orthodox. There are parts of the United States that are like this (Bible belt :)but we are so pluralistic and have never had a state church so this attitude hasn't taken root. One thing that is similar between all the different church expressions here and abroad is that the youth need to make a voluntary commitment or the faith will face extinction.
