'Every day brings to the Christian many hours in which he will be alone in an unchristian environment. These are the times of testing. This is the test of true meditation and true Christian community. Has the fellowship served to make the individual free, strong, and mature, or has it made him weak and dependent? Has it taken him by the hand for a while in order that he may learn again to walk by himself, or has it made him uneasy and unsure? This is one of the most searching and critical questions that can be put to any Christain fellowship.'
Dietrich Bonhoeffer, Life Together, p.67.
