This is a faithful saying: if a man seeks the office of an overseer{Or, bishop}, he desires a good work.
He desireth an excellent work The Apostle affirms that this is no inconsiderable work, such as any man might venture to undertake. When he says that it isκαλός, I have no doubt that he alludes to the ancient Greek proverb, often quoted by Plato, δύσκολα τὰ καλά, which means that “those things which are excellent, are also arduous and difficult;” and thus he unites difficulty with excellence, or rather he argues thus, that it does not belong to every person to discharge the office of a bishop, because it is a thing of great value.
