Sarah,
I want to be sensitive to the larger topic of the forum so I will keep my response short. My comment regarding the broadcasted message and the value of community is based on thoughts I have been having about the nature of church communities and the role of pastor/elders/deacons/leaders i.e. shepherds. I do think there is something inherently integral between a shepherd and their sheep. This relationship is critical and I think the church (in general) needs to do a little more thinking about it. In today's electronic age, it is even a more crucial question. There is much to be said theologically about the role of the shepherd but that is for another time and place.
While the broadcast message solves a pragmatic problem (the problem of resources), it does not solve an underlying deeper one (the problem of leadership i.e. shepherd development if you will). The issue of leadership is a fundamental problem at most churches not just Rooftop. I simply would hate to see a church use their precious resources to merely put up a projector and a screen than to use some of these resources to develop leaders (which is an outgrowth of a churches discipleship efforts).
