91. The fathers have added another allegory taken from the form and dimensions of the ark. The human body, measured from the top of the head to the sole of the foot, is six times as long as it is wide. Now, the ark, which was fifty cubits wide, measured six times as much in length, namely 300 cubits. Hence, they say, the ark typifies Christ the man, in whom all promises center. Therefore, those who believe in him are saved even in the midst of the flood, that is, in death itself.
92. This conception is both appropriate and beautiful; above all, it agrees with faith. Though there may be a mistake in the application, the groundwork is strong and secure. There is no doubt that the Holy Spirit found various ways to illustrate the promises to be fulfilled in Christ, and the wonderful counsel of salvation for mankind through faith in Christ. Hence, allegories of this nature, though lacking in aptness, are not necessarily wicked and a source of offense.
93. If one were to say the sun represents Christ, while the moon represents the Church, which receives its light by the grace of Christ, he might possibly be mistaken in his choice of illustration, yet his error is based, not upon an erroneous, but upon a sure foundation. But when the pope declares the sun represents the papal authority, while the moon represents the emperor's, then not only the application is inapt and foolish, but the very foundation is evil. Such allegories are not conceived and invented by the Holy Spirit, but by the devil, the spirit of lies.
94. Allegories must have some application to the promises and the doctrine of faith if they are to comfort and strengthen the soul. Peter's allegory teaches us this. Because Peter saw that Noah was set free in the midst of death and that the ark was an instrument of life, the ark was rightly applied to typify Christ. Only divine power can save in the midst of death and lead unto life. The Scriptures declare that to God belong the issues from death, (Ps 68, 21), and he makes death the occasion, yea, even an aid to life.
95. This has given rise to expressions used in Scripture, where afflictions and perils are likened to a cup that intoxicates. This is an apt and vivid figure of speech. So the passion of Christ is called a draught from a brook (Ps 110, 7), meaning that it is a medicinal draught or mixture, which, though bitter, is healing in its bitterness and gives life by causing death. Such soothing words serve to console us that we may learn to despise death and other perils and meet them with greater readiness.
96. Satan, also, has his cup; but it is sweet, and inebriates unto nausea. He who, attracted by its sweetness, drinks it, loses his life and dies the eternal death. Such was the cup the Babylonians drained, as the prophet has it (Jer 25, 15-27). Let us, therefore, accept the cup of salvation with thanksgiving, and, as Paul declares of believers, rejoice in tribulation (Rom 5, 3).
