"As dead flies give perfume a bad smell, so a little folly outweighs wisdom and honour." (Ecclesiastes 10:1)
As dead flies give perfume a bad smell, so a little folly outweighs wisdom and honour. The heart of the wise inclines to the right, but the heart of the fool to the left. Even as fools walk along the road, they lack sense and show everyone how stupid they are. If a ruler's anger rises against you, do not leave your post; calmness can lay great offences to rest. Whoever digs a pit may fall into it; whoever breaks through a wall may be bitten by a snake. Whoever quarries stones may be injured by them; whoever splits logs may be endangered by them. If the axe is dull and its edge unsharpened, more strength is needed - but skill will bring success. The words of the mouth of the wise are gracious, but fools are consumed by their own lips.
The Catechism draws from the dead fly image the principle of moral proportionality: a small but persistent vice can corrupt a life of otherwise genuine virtue, as a single dead fly ruins a jar of perfume (CCC 1858).
Brothers and sisters, a little folly outweighs wisdom and honour. The reputation built over years can be destroyed in a moment of small and foolish indulgence. Guard the small sins as carefully as the large ones. The dead fly in the perfume is not a lion - it is a fly. But the perfume is ruined all the same.
Lord God, guard us from the small folly that ruins the large virtue. Keep even the dead flies out of the perfume of our lives. Through Christ our Lord. Amen.
