Quote from : Unchristian: What a New Generation Really Thinks about Christianity...and Why It Matters Book

When outsiders claim that we are unchristian, it is a reflection of this jumbled (and predominately negative) set of perceptions. When they see Christians not acting like Jesus, they quickly conclude that the group deserves an unchristian label. Like a corrupted computer file or a bad photocopy, Christianity, they say, is no longer in pure form, and so they reject it. One quarter of outsiders say therefore most perception of Christianity is that the faith has changed for the worse. It has gotten off-track and is not what Christ intended. Modern-day Christianity no longer seems Christian.
