When is community, community? This is a question I have been grappling with. The New Testament seems to take the concept of community for granted (see Acts). What makes community authentic today? One area is when we can come to the realization that relationships are more important than being correct. We must also come to an understanding that we are not the most important person (aspects of servant hood). Others can actually be more important than "I" or "me."
It's my firm belief that the concept of family needs to re-enter our vocabulary of the church and community. Until this happens i believe authentic christianity will remain elusive.
Malcolm Chamberlain has an interesting take on community, here.
