Job 39:9

"Do you want the unicorn to serve? The one who is proud here below of his high rank? Christ has been able to subject such men to his power, he has established ministers of his Church. The Greek word used, monokeros, means well "Who has only one horn; He designates the proud. "Will he come to rest in his barn? As one relies on the humility of the One who was born in a barn (3). One is happy there for the forgiveness of one's sins, one forgets the worries of a disorderly conscience.

"Is the unicorn willing to serve you?" This animal, as is reported, is similar to an ox and is found in the austral regions, armed with a single horn. In the unicorn, whoever is not subjected at all to the bondage of the world is covertly represented. It is said to be provided with a single horn, because there is only one truth for the righteous. Again the human soul is compared with the unicorn, and it must be defined as endowed with a single horn if it is led by a single movement to the top. Moreover, it is said that the unicorn cannot be caught as its strength and dangerousness are extreme. However, the virgin hunter can win it, after being captured by the pleasure of beauty. So the soul is caught by the things that it has loved.

Will the rhinoceros be willing to serve thee? 2. For the rhinoceros is quite of an untamed nature, so that, if it is ever taken, it cannot in any way be kept. For, as is said, it dies immediately from being unable to bear it. But its name when interpreted means in the Latin tongue, 'a horn on the nostril.' And what else is designated by the nostril, but folly; what by the horn, but pride? For that folly is usually understood by the nostril, we have learned on the evidence of Solomon, who says; As a ring of gold in a swine's nostrils, so is a beautiful and foolish woman. [Prov. 11, 22] For he saw heretical doctrine shining with brilliancy of eloquence, and yet not agreeing with the proper understanding of wisdom, and he says, A ring of gold in a swine's nostrils; that is, a beautiful and involved expression in the understanding of a foolish mind: from which gold depends, through its eloquence, but yet, through the weight of earthly intention, like a swine, it looks not upwards. And he proceeded to explain it, saying, A beautiful and foolish woman: that is, heretical teaching; beautiful in words, foolish in meaning. But, that pride is frequently understood by a horn, we have learned on the evidence of the Prophet, who says; I said to the wicked, deal not wickedly, and to the sinners, lift not up your horn. [Ps.75, 4] What is, therefore, designated by this rhinoceros, but the mighty of this world, or the supreme powers themselves of the kingdoms therein, who, elated by the pride of foolish boasting, whilst they are puffed up by false honour without, are made inwardly destitute by real miseries? To whom it is well said; Why boastest thou, O dust and ashes? [Ecclus. 10, 9] But at the very beginning of the rising Church, when the might of the wealthy was raising itself against her, and was panting for her death, with the unboundedness of so great cruelty, when, anxious from so many tortures, and pressed by so many persecutions, she was giving way; who could then believe that she would subdue those stiff and stubborn necks of the haughty, and would bind them, with the gentle bands of faith, when tamed by the yoke of holy fear? For she was tossed about, for a long while, in her beginnings, by the horn of this rhinoceros, and was struck by it, as though to be utterly destroyed. But by the dispensation of Divine grace, she both gained life and strength by death, and…
