well, let me start with the disclaimer that i'm still thinking all of this through. i am completely open to continued dialog on this subject and am completely willing to hear other opinions.
that said, i think that there are several terms that need to be redefined:
1) preaching-i think that gary has the right idea in the way he presents the word on sundays. to me, it seems more of a discourse that is open to conversation...much like jesus does consistently through scripture (not that i'm comparing gary to jesus

) We need to get away from what preaching has become: speeching (for more on this read
preaching re-imagined by doug pagitt)
2) church-this is a red flag word for so many people in today's culture because those people (me included) have been hurt, scorned, lied to, etc. by institutions called churches. we need to make it clear that the church is not an institution but the people that make it up.
3) christian-i'm going to go ahead and chalk this whole concept in my mind up to donald miller (even though i kind of feel like quoting
blue like jazz in today's christian culture is seriously cliche). but miller does make the point that the term christian has so many varied definitions in today's culture that it is hard to connect with people who aren't christians on many occasions.
i also think, in addition to redefining some terms (the previous list is
not all inclusive), we have to be very mindful of the culture we live in. i come from a very conservative fundamentalist white southern baptist background. i have learned over the past couple of years that this is not a bad thing. however, i think that if the church i dream of is going to be successful and even possible then we have to look toward a church that is not conformed to the culture but adapted to it. i am a sold-out believer in multi-cultural, multi-generational communities of faith. i think that the more perspectives present in an intentional christian community, the more that community can grow in a deeper understanding of god and how much he loves us.
that's really all my ranting for now, but fyi, this is one of my favorite topics of conversation.

feel free to pick my brain anytime.
