I keep seeing a Bonhoeffer quote about community go around that I think is a loose paraphrase. Here’s the real quote:

Every human idealized image that is brought into the Christian community is a hindrance to genuine community and must be broken up so that genuine community can survive. Those who love their dream of a Christian community more than the Christian community itself become destroyers of that Christian community even though their personal intentions may be ever so honest, earnest, and sacrificial.
