Let's reserve this title for Jesus, shall we?
"So in the first century, no Christian would dare take the title of sole ruler, overseer, or pastor of the church .... There is only one flock and one Pastor (John 10:16), one body and one Head (Col. 1:18), one holy priesthood and one great High Priest (Heb. 4:14ff.), one brotherhood and one Elder Brother (Rom. 8:29), one building and one Cornerstone (1 Pet. 2:5ff.), one Mediator, one Lord. Jesus Christ is 'Senior Pastor,' and all others are his undershepherds (1 Pet. 5:4)." -- Alexander Strauch.
