My main fear about modern forms of Christianity is that they treat men like angels and not men. Such terms as "purify", "rationalize", and "reform" thus send nervous shivers down my spine. I of course do not think that the average Christian should be in the dark, but he should also realize that there is not a whole lot of light in what we believe either. We are still very much in the shadows.
The Gospel is about realizing what is important in our relationship with God, not about purging all elements we might deem as suspicious. Christianity is a religion for human beings, not for angels. That means it will at times seem superstitious, hypocritical, and contradictory. So be it. It is a hospital for souls, not a spectacle of angelic grace.
