Bonhoeffer on Pious Purists and a "Perfect" Church

Strong and weak, wise or foolish, talented or untalented, pious or less pious, the complete diversity of individuals in the community is no longer reason to talk and judge and condemn, and therefore no longer a pretext for self-justification. Rather this diversity is a reason for rejoicing in one another and serving one another....Every Christian community must know that not only do the weak need the strong, but also that the strong cannot exist without the weak. The elimination of the weak is the death of the community. -- from Life Together
