Robert Capon in The Foolishness of Preaching:
If we are ever to enter fully into the glorious liberty of the children of God, we are going to have to spend more time thinking about freedom than we do. The church, by and large, has had a poor record of encouraging freedom. It has spent so much time inculcating in us the fear of making mistakes that it has made us like ill-taught piano students: we play our pieces, but we never really hear them because our main concern is not to make music but to avoid some flub that will get us in trouble. The church, having put itself in loco parentis (in the place of a parent), has been so afraid we will lose sight of the need to do it right that it has made us care more about how we look than about who Jesus is. It has made us act more like subjects of a police state than fellow citizens of the saints.
