Jesus had already called elder arrangement as pagan when he said: "But Jesus called them to Himself and said, "You know that the rulers of the Gentiles lord it over them, and their great men exercise authority over them. It is not this way among you, but whoever wishes to become great among you shall be your servant," (Mathew 20:25, 26)
Behind the words, he concealed the notion we are familiar with: No ladder of authority among Christians.
