Some further points re structure, beyond the Jerusalem church and synagogue models. Another type of structure encountered is the small group or cell (Acts 2:42-47) whose members met in each others' homes. This was particularly true of towns other than Jerusalem. It should be noted here that homes then tended to be much larger than those today and therefore they would have had more people than an average small group in modern times. This was a model that persisted during the years of persecution.
For further study, I have already referred to Richard Ascough's commentary 'What are they saying about the formation of the Pauline churches?' in which he draws from a variety of sources. His study concentrates on four pre-Christian insitutions/ belief systems which, to a greater or lesser extent formed the basis of Pauline ecclesiology: the synagogue, the philosophical school (eg; Paul teaching in the schole of Tyrannus in Acts 19:9), the ancient mysteries (for example the baptismal theology of Rom 6:1-11) and the voluntary associations that existed in the Greek world at the time from which it is likely that the concept of the cell or house church described above was derived. It is important of course that we do not take Paul as compromising with the world in this way but rather that he possibily adopted/ adapted elements of these pre-Christian models so as to be relevant and speak into the socio-religious milieu of the period. We do well to remember that Christianity and the church did not spring ex nihilo, from a vacuum; words such as ecclesia/ qahal and baptism had meanings before they became Christian.
Disputes in the church seem to have been settled by church council (Acts 11,15). Splits were discouraged, the minority fell into line. At the Council of Jerusalem in Acts 15, a very interesting picture emerges of church government, responsibility and functions; Peter and James represented the Twelve, James Silas and Jude the local elders; Paul and Barnabas correspond to Peter and James, Titus to Silas and Jude on a missionary level. The Twelve were in overall control. There appear to have been two parallel leadership groups: local and static (elders) (modal) and missionary (apostles prophets and teachers) (sodal).
We also have an obvious difference between Acts 14:23 and the Pastorals (appointment of elders to the office of oversight with the Eph 4 'five-fold ministries' and I Cor 12:28 ministries (apostles prophets teacher etc). This is explained by the different circumstances of the churches but there is a ref to elders at Ephesus (Acts 20:17) so the twin concepts of ministry and office exist side by side, although it is fair to say that the idea of elders in Acts was probably different from that in the Pastorals. There is also the problem that the Philippian church had overseers-bishops and deacons (episkopoi and diakonoi - Phil 1:1). A further muddying of the waters is that Acts 13:1 has prophets and teachers at Antioch; prophetic 'office' seemed to follow the ministry here - prophets were people who prophesied.
Other leadership-office-ministry pictures are found in the follwing verses and terms: Acts 20:28 -prosechete (take heed): Acts 20:28, Heb 12:15 - episkopos/episkopontous (overseers, taking care);I Cor 12:28, Titus 2:15, I Thess 5:11, I Tim 4:13 - paraklesei (encourage, exhort, comfort); Acts 20:28, Eph 4:11 - poimanein (shepherd, pastor); Col 3:16, I Tim 6:2, I Cor 12:28; Eph 4:11 - didaskontes (teaching, teacher)
So, what more evidence do you need of pluriformity?
Yours in Christ
