There is little at all in the New Testament about the governing structure of the church for good reason .. it isn’t important. We are given freedom to organize according to what works best in a given culture or society. CHRISTianity is not about the church, it’s about CHRIST, that’s why it isn’t called CHURCHIANITY.
“Jesus Christ, first, last and always.”
And in the end, we all, every single last one of us, answer to JESUS and Jesus alone.
