An overseer. In apostolic times, it is quite manifest that there
was no difference as to order between bishops and elders or
presbyters (Acts 20:17-28; 1 Pet. 5:1, 2; Phil. 1:1; 1 Tim. 3).
The term bishop is never once used to denote a different office
from that of elder or presbyter. These different names are
simply titles of the same office, “bishop” designating the
function, namely, that of oversight, and “presbyter” the dignity
appertaining to the office. Christ is figuratively called “the
bishop [episcopos] of souls” (1 Pet. 2:25).
