[Phillip,
Based upon your above statement, I have a question.
Does one who is a "leader" or "main preacher" in a fellowship/church need to be "ordained"?]
You can preach without being ordained an elder, but it appears to be the order of the apostles to have publically recognized elder everywhere. Elders exercise God given authority in the local church.
Titus 1:5 5 This is why I left you in Crete, so that you might put what remained into order, and appoint elders in every town as I directed you.
This was necessary because of all those empty talkers and slow bellies that would otherwise corrupt the church. Titus 1:10-16
In our case, the fellowship are partly members who came out of a church with very strict practices, over and above what the bible demands. So we are not a church plant, but a group or leavers that wanted to continue fellowship.
I may have found a man who can help us, just waiting to hear back from him.
