Which passage describes today's model?
This...
Then Ezra the priest brought the law before the assembly of men, women and all who could listen with understanding, on the first day of the seventh month. He read from it before the square which was in front of the Water Gate from early morning until midday, in the presence of men and women, those who could understand; and all the people were attentive to the book of the law. Ezra the scribe stood at a wooden podium which they had made for the purpose. And beside him stood Mattithiah, Shema, Anaiah, Uriah, Hilkiah, and Maaseiah on his right hand; and Pedaiah, Mishael, Malchijah, Hashum, Hashbaddanah, Zechariah and Meshullam on his left hand. ... Then Ezra blessed the LORD the great God. And all the people answered, "Amen, Amen!" while lifting up their hands; then they bowed low and worshiped the LORD with their faces to the ground. ... They read from the book, from the law of God, translating to give the sense so that they understood the reading. ... All the people went away to eat, to drink, to send portions and to celebrate a great festival, because they understood the words which had been made known to them. Nehemiah 8:2-4, 6, 8, 12

What is the outcome then, brethren? When you assemble, each one has a psalm, has a teaching, has a revelation, has a tongue, has an interpretation. Let all things be done for edification. 1 Corinthians 14:26
Ezra and the other leaders stood on a high wooden platform (v. 4), lead the people in worship (v. 6), read from God's Word (v. 3), explained the meaning (v. 8), and then dismissed the crowd around midday (v. 12) so everyone could go eat. The New Testament says the believers broke bread "from house to house." It was open and participatory for all members. Biblical elders watched over the meetings to ensure heresies did not creep in, that the unity of peace in the Spirit was not disrupted, that fellowship was not diminished, and that all was done orderly (not chaotic) for the edification of all present. Biblical elders were not authorities over anyone and did not lord it over the people; they were servants who served the Body. When they did wrong, they were to be rebuked before the entire Congregation (1 Tim. 5:20). Does that sound like today's model in the least? Today's model is based on Command and Control.
