The pastoral (or ministerial) office is an office instituted by God, executed in the Old Testament under the title of “priest” and in the New Testament under the title of “pastor.” Although commission and calling are executed by human agency, they are nevertheless executed in the name of God. Each pastor must therefore conduct himself as an ambassador of God. “Now then we are ambassadors for Christ” (2 Cor 5:20).
