Following other writings by Paul we can assume the model that may best serve this purpose is one of interaction among all present. This allows each one to contribute their "gift" for the benefit of someone else and hopefully build them up in their lifestyle. The biblical model is clearly defined in this way. It is not top down (an American model) but more lateral.
Are there communities in Christendom that are willing to risk deconstructing a weak model for one that produces God's results in God's way?
