Tony Payne, writing from "down under" for the Sola Panel, writes on the nature of the New Testament Church. His background (Anglican) and setting (Australia) may be different from mine, but I think that he hits a home run (or maybe he "hit for five") with this description of the nature of the New Testament church:
"...a group of Christian people (of any size), with a qualified elder or overseer (or more than one, appointed or elected, we care not how), meeting in the name and presence of Christ in any location, at any time of day, on any day of the week, with any frequency (so long as it was regular and often), at which time they spoke and heard God's word together (through Bible reading, preaching/teaching, prophetic encouragement, etc.), and responded in prayer and thanksgiving, with the result that God is glorified in Christ and the people edified."
