ENTER THE NICOLAITANS (general)
Notice that Jesus did not condemn these established Churches for assembling with a hierarchical structure.. but for specific practices. The Nicolaitans were known to eat food sacrificed to idols. They claimed to be a modernized version of Christianity. Despite your presumption that the rebuke of the Nicolaitans is a rebuke of delegated power, the Nicolaitans claimed to be followers of Nicolas.. one of the first seven ordained to the priesthood by the apostles in Acts 6:5.
I asked The Lord how much He loved me
He stretched out His arms and said, "this much"
Then He died for me
