Of ants
The ant has three characteristics. The first is that they march in line, each one carrying a grain of corn in its mouth. Those who have none do not say to the others: 'Give us some of your grain', but follow the tracks of those who first went out to the place where they find the corn and carry it off to their nest. Let this description serve to signify sensible men, who, like the ants, act in unity, as a result of which they will be rewarded in the future.
The ant's second characteristic is that when it stores grain in its nest, it divides its supply in two, lest by chance it should be soaked in the winter rains, the seed germinate and the ant die of hunger. In the same way, you, O man, should keep separate the words of the Old and the New Testament, that is, distinguish between the spiritual and the carnal, lest the law interpreted literally should kill you, for the law is a spiritual thing, as the Apostle says: 'For the letter killeth, but the spirit giveth life' (2 Corinthians, 3:6). For the Jews, who paid attention only to the letter of the law and scorned its spiritual interpretation, have died of hunger.
The ant's third characteristic is that at harvest time it walks through the crop and finds out by nibbling the ears whether it is barley or wheat. If the crop is barley, the ant goes to another ear and sniffs it, and if it smells wheat, it climbs to the top of the ear and carries off the grain to its nest. For barley is food for beasts. As Job says: 'Barley grew for me instead of wheat' (see Job, 31:40), meaning the doctrine of heretics. For heresy is like barley, and should be cast away, because it shatters and destroys men's souls. Therefore, Christian, flee from all heretics; their teachings are false and hostile ...
