The overseer therefore must be without reproach, the husband of one wife, temperate, sensible, modest, hospitable, good at teaching;
Apt to teach ... The Christian life is a life of study and learning. Ill-informed elders are a contradiction in terms.  Every elder should be able to shut the mouths of the gainsayers, shield the church from false teaching, and see to it that truth and truth alone is fed to their charges. The inroads of so-called "higher" or "source" criticism of the New Testament, the current development of the most notorious and amoral philosophies, the advocacy of such things as homosexuality, abortion, etc., place an additional burden upon elders to be well taught and able men.  As Lenski said, "Aptness to teach means not merely a natural aptitude, but the qualification of having been taught, as well."[20] It is regrettable that this qualification is sometimes overlooked.
