Genesis 7:17

With the eye of my mind
I gazed upon paradise.
The summit of every mountain
is lower than its summit,
the crest of the flood
reached only its foothills,
these it kissed with reverence
before turning back
to rise above and subdue the peak
of every hill and mountain.
The foothills of paradise it kisses,
while every summit it buffets.

It is not without purpose that Scripture describes all this to us. Instead, its purpose is for us to learn that not only people, cattle, four-footed beasts and reptiles were drowned but also the birds of heaven and whatever inhabited the mountains, namely, animals and other wild creatures. Hence the text says, “The flood rose fifteen cubits above the mountains,” for you to learn that the execution of the Lord’s sentence had been effected. He said, remember, “After seven more days I will bring a deluge upon the earth and I will wipe off the face of the earth all the life I have made, from human beings to cattle, and from reptiles to birds of heaven.” So Scripture narrates this not simply to teach us the flood level but that we may be able to understand along with this that there was absolutely nothing left standing—no wild beasts, no animals, no cattle—rather, everything was annihilated along with the human race. Since it was for their sake that all these creatures had been created, with the imminent destruction of the human beings it was fitting that these creatures too should meet their end. Then, after teaching us the great height reached by the flood waters and the fact that they rose a further fifteen cubits above the mountain peaks, it further adds out of fidelity to its characteristic precision, “There perished all flesh that moved on the earth—birds, animals, every reptile that moved on the earth, every human being—everything that had breath of life, everything on dry land: all perished.” That was not an idle reference in the words “everything on dry land”; instead, its purpose was to teach us that while others perished, the just man with everyone in the ark alone was saved.

But let us see where this most sacred number of forty days had its beginning. We read first in the Old Testament that in the time of Noah, when criminal wickedness had seized the whole human race, torrents of water poured forth from the opened floodgates of heaven for just as many days. In a kind of mysterious image of Quadragesima, this inundation of the earth refers not so much to a flood as to baptism. This was clearly a baptism in which the wickedness of sinners was removed and Noah’s righteousness preserved. For this reason, then, the Lord has given us forty days now as well in imitation of that time, so that for this number of days, while the heavens are opened, a celestial rain of mercy might pour upon us and, with the flood, the water of the saving washing might enlighten us in baptism and—as was the case then—the wickedness of our sins might be quenched in us by the streams of water and the righteousness of our virtues preserved. For the very same thing is at issue with regard to Noah and in our own day: baptism is a flood to the sinner and a consecration to the faithful; by the Lord’s washing, righteousness is preserved and unrighteousness is destroyed.

And the waters increased and lifted the ark high above the earth, the waters increased greatly and filled everything on the surface of the earth. And the waters of baptism and faith, multiplied throughout the whole world, raise the Church from the desire for earthly things to the hope and desire for heavenly life; but also from where the tribulations frequently striking the Church, the more intensely they filled everything, the higher they compelled her to seek the joys of another life: which is well indicated in sacred history, when it is said that the Amorite confined the children of Dan, in the mountain, and did not give them the place to descend to the plains. For the Amorite indeed is interpreted as Bitter, Dan as Judging or Judgment; and who are signified by the sons of Dan, if not those who diligently examine all they do, so that it may be right, in the balance of truth, who, walking by the light of the word of God, swear and decide to keep His judgments of justice; and who are expressed through the Amorite, if not those who attempt to disturb or even overthrow the sweetness of the life of the saints with the bitterness of tribulations? And the Amorite confines the sons of Dan in the mountain, and does not allow them to descend to the plains, as often such a violent storm of persecutions afflicts the elect, that they are not permitted to indulge in any time for weak thoughts; but living in the highest continence, they must devote themselves continually to prayers and fastings and the meditations of the divine Scriptures, so that by greater exercise of virtues they may be able to overcome greater struggles of temptations.
