The precise form of ignorance or lack of understanding described here is shown by the contrast. The ignorant man is compared with one who hates every form of covetousness, sharp practice, and acquiring of gain through injustice.
Again, how different is this to the type of authority which ought to exist in the church of Jesus Christ, who told his disciples, ‘The kings of the Gentiles exercise lordship over them; and they that exercise authority upon them are called benefactors. But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve’ (Luke 22:25-26). No surprise therefore that the qualification for elders includes, ‘not greedy of filthy lucre’ (1 Timothy 3:3), and that Paul was eager to demonstrate that in preaching the gospel he did not use ‘a cloke of covetousness’ (1 Thessalonians 2:5). Instead they must be those who can be perfectly trusted to take care of that which is not their own, and for whom it would be unthinkable to take advantage of their office. They have integrity in the heart which is maintained before God and not just before men.
