This is a faithful saying: if a man seeks the office of an overseer{Or, bishop}, he desires a good work.
(47) “Let us know that the Holy Spirit, speaking of those who are ordained ministers of the word of God, and who are elected to govern the Church, calls them Pastors. And why? Because God wishes us to be a flock of sheep, to be guided by him, hearing his voice, following his guidance, and living peaceably. Since, therefore the Church is compared to a flock, they who have the charge of guiding the Church by the word of God are called Pastors. And next, the word Pastor means Elder not by age, but by of office: as, at all times, they who govern have been called Elders, even among heathen nations. Now the Holy Spirit has retained this metaphor, giving the name Elder to those who are chosen to proclaim the word of God. He likewise calls them Bishops, that is persons who watch over the flock to show that it is not a rank unaccompanied by active exertion, when a man is called to that office, and that he must not make an idol of it, but must know that he is sent to obtain the salvation of souls, and must be employed, and watch, and labor, for that purpose. We see then the reason of these words; and since the Holy Spirit hath given them to us, we must retain them, provided that they be applied to a good and holy use.” — Fr. Ser.
