No, I suspect perfect wouldn't quite match that answer.
So...elders are to ensure the maturity and safety of the congregation, and to ensure the passing on of the faith (the real core faith, not denominational doctrine). "Administrative elder" is an oxymoron and demonstrates a significant misunderstanding of the concept.
An elder should reflect Jesus in his life and in the ways he interacts with people and congregational members.
Oddly enough, a perfect elder need not be perfect, but open and accessible for discussion, instruction, and reproof when needed.
An elder should have a sufficient grasp of and commitment to the faith that he can explain it's core elements to others, and he should see the mission of the church in the world as the work of God - and want it done.
He should continue to learn, read, and reflect on the faith, the life of the community, and himself.
