Early Church Structure According to the Scriptures
The Bible describes the local congregation as having an Overseer (also called a Bishop), which I take to be an administrator and expediter of the whole. One aspect of meetings is that any of the Christians attending who have something to speak forth on behalf of God (called Prophets) should stand and deliver it to the whole congregation in an orderly manner, that is, not interrupting each other and giving way in a loving way so others can speak. Elders are older Christians who handle various problems and organize subcommittees, like those who made sure all the qualifying widows got their share of support from the congregation; note that they were spiritual, though their job seems basically mundane; perhaps it was because daily maintenance of the qualifying widows took a particular love. And congregations seem to have been places where the Christians could meet each other on a more or less equal footing, which is in stark relief and great contrast with the hierarchical consumption we have today.
What other aspects of church life can be perceived in God's Word after the New Covenant?
