If you
"always had a presence apart from the Institutional Churches", but have no evidence and no names, then you are asserting a belief based on theory with no supporting facts.
Independent Evangelical churches follow the Baptist Successionist idea that the early church was de-centralized. They like to imagine that the early Christians met in their homes for Bible study and prayer, and that in this pure form they existed independently of any central authority. It is easy to imagine that long ago in the ancient world transportation and communication was rare and difficult and that no form of centralized church authority could have existed even if it was desirable.
The most straightforward reading of the Acts of the Apostles shows this to be untrue, and a further reading of early church documents shows this to be
no more than a back-projected invention. In the Acts of the Apostles what we find is a church that is immediately centralized in Jerusalem. When Peter has his disturbing vision in which God directs him to admit the Gentiles to the Church, he references back at once to the apostolic leadership in Jerusalem.(Acts 11:2)
The mission of the infant church was directed from Jerusalem, with Barnabas and Agabus being sent to Antioch (Acts 11:22,27) The Council of Jerusalem (Acts 15) was convened to decide on the Gentile decision and a letter of instruction was sent to the new churches in Antioch, Syria and Cilicia. (Acts 15:23) We see Philip, John Mark, Barnabas and Paul traveling to and from Jerusalem and providing a teaching and disciplinary link from the new churches back to the centralized church in Jerusalem.
After the martyrdom of James the leadership shifts to Peter and Paul. The authority is not centered on Jerusalem, but through their epistles to the various churches, we see a centralized authority that is vested in Peter and Paul as apostles. This central authority was very soon focussed on Rome, so that St Ignatius, a bishop of the church in Antioch would write to the Romans in the year 108 affirming that their church was the one that had the
“superior place in love among the churches.’”
We find no evidence of a network of independent, local churches ruled democratically by individual congregations. Instead, from the beginning we find the churches ruled by elders (bishops) So in the New Testament we find the apostles appointing elders in the churches. (Acts 14:23; Titus 1:5) The elders kept in touch with the apostles and with the elders of the other churches through travel and communication by epistle. (I Peter1:1; 5:1)
In the early church we do not find independent congregations meeting on their own and determining their own affairs by reading the Bible. We have to remember that in the first two centuries there was no Bible as such for the canon of the New Testament had not yet been decided. Instead, from the earliest time we find churches ruled by the bishops and clergy
whose authenticity is validated by their succession from the apostles.
