The sixth tower is that of understanding, of which Song of Songs 7: "Your neck is like a tower of ivory: your eyes are like the pools in Heshbon"; where is given to be understood the purity of heart and the clarity of spiritual intelligence. The seventh is the tower of wisdom, of which Song of Songs 8: "I am a wall, and my breasts are like a tower"; which is said on account of the consolation that is in the tasting of the milk of the breasts of divine wisdom.
But before the height of this building is raised, the construction of the building of the seven virtues is necessary, of which Proverbs 9: "Wisdom has built herself a house, she has hewn out seven pillars." Moreover, of this building Christ is the founder and the foundation and also the completion. Nevertheless, the spiritual man is compared to this building: whence 1 Corinthians 3: "We are God's co-workers, you are God's husbandry, you are God's building." Therefore everyone who purposes to ascend to the pinnacle of virtue, this one wishes to build a tower.
58. Second, with regard to the provision of sufficient resources, he adds: Does he not first sit down and calculate the expenses that are necessary, whether he has enough to complete it? To sit is to consider within oneself the secrets of one's conscience: Lamentations 3: "He will sit alone and be silent." To calculate is to foresee through careful consideration: hence the Gloss: "Everything that we do, we ought to anticipate through the effort of consideration." And this is what is said in Proverbs 4: "Let your eyes see what is right, and let your eyelids precede your steps." The expenses, however, that are necessary are the sufficient efforts of the mind, by which one cooperates with the grace of Christ courageously, according to that Psalm: "Act courageously, and let your heart be strengthened, all you who hope in the Lord"; profitably, hence 1 Corinthians 3: "But if anyone builds upon this foundation gold, silver, and precious stones," etc.; efficaciously: Hebrews 12: "See to it that no one falls short of the grace of God," etc.; perseveringly: 3 Kings 7: "He completed all the work that Solomon was doing in the house of the Lord."
When this building is completed, the Lord appears to dwell therein: hence 3 Kings 9: "It came to pass, when Solomon had finished the building of the house of the Lord and the building of the king and all that he had desired, the Lord appeared to him." These expenses sufficient for completing therefore consist in the resolve of the will acting courageously, profitably, efficaciously, and perseveringly. But if anything is lacking, the Lord supplies it: hence Philippians 2: "It is God who works in us both to will and to accomplish according to his good will." Whoever wishes, therefore, to begin a lofty work ought to foresee whether he is willing to persevere: because, as is said above in chapter nine, "No one putting his hand to the plow," etc.
59. (Vers. 29.). Third, with regard to the avoidance of impending reproach, he adds: Lest, after he has laid the foundation, namely by undertaking a higher state in imitating Christ — and this is to lay the foundation: First Corinthians 3: "For no one can lay another foundation besides that which has been laid, which is Christ Jesus." One begins to lay this foundation through faith and good works, according to Matthew 7: "Everyone who hears these words of mine and does them is like a man who built his house upon the rock." Upon this rock he places the foundation of his dwelling who wishes to imitate Christ perfectly, according to Jeremiah 48: "Leave the cities and dwell in the rock, O inhabitants of Moab," etc. And is not able to finish it, namely through perseverance, as are those of whom it is said above in chapter eight: "They believe for a time and in the time of temptation they fall away." Such are those who destroy by relapsing whatever they had built up by beginning well; Ecclesiasticus 34: "One building and another destroying, what profit have they but labor?" Such are the lax and remiss: Proverbs 18: "He who is soft and lax in his work is the brother of him who squanders his own works."
All who see it, by observing the perfection that was begun; First Corinthians 4: "We have been made a spectacle to the world, and to angels and to men." For what is placed on high is shown to all: Matthew 5: "A city set on a hill cannot be hidden, nor do they light a lamp and put it under a bushel, but upon a lampstand, that it may give light to all who are in the house."
60. (Vers. 29. 30.). They begin to mock him, saying: Because this man began to build and was not able to finish: and this by inflicting insults and deriding, because it is greatly shameful for those who turn back and apostatize. For they are mocked by demons; Lamentations 1: "The enemies saw her and mocked at her sabbaths." The spiritual man abhors this mockery: the Psalm: "Neither let my enemies mock me," etc. These enemies mock the incompleteness, according to Nehemiah 4: "Tobias the Ammonite said: Let the Jews build; if a fox goes up, he will leap over their stone wall." Whence Ambrose says: "In everything we do, we ought to consider the hidden adversaries who lie in wait for our works, and unless we keep watch against them, we suffer as mockers those whom we have as persuaders to evil." But he who turns back from what he has begun is mocked for rashness in presuming, for inconstancy in pursuing, for faintheartedness in desisting — and this not only by the devil, but also by the world: Ecclesiasticus 20: "The fool shall have no friend, and there shall be no thanks for his good deeds"; and further: "How often and how many shall mock him," etc.
61. (Verse 31.). Or what king going to engage etc. Above he proposed the parable of the man building, here he proposes the parable of the king waging war; in which part indeed three things are introduced, namely the proposal of war, the foresight of danger, and the provision of remedy.
First therefore, as to the proposal of war, he says: Or what king going to engage in war against another king. This king is anyone who governs himself according to the law of God: Proverbs 20: "The king who sits on the throne of judgment" etc.; and Apocalypse 5: "You have made us a kingdom for our God, and we shall reign upon the earth." It belongs to this one to engage in war: because, Job 7, "the life of man upon earth is a warfare." This, however, is to be understood in three ways: either that one engages in war with the king of pride, of whom Job 41: "He is king over all the children of pride"; or with the king of justice, of whom in the Psalm: "You shall rule them with a rod" etc.; or with the king of heavenly providence, of whom Ecclesiastes 5: "Moreover, the king of the whole earth commands" etc.
He engages in war with the king of pride when he dissents from him: Ephesians 6: "Our wrestling is not against flesh and blood, but against the rulers of the world of this darkness." He also engages in war with the king of justice when he wishes to justify himself in the sight of God, because it is said in Jeremiah 2: "Behold, I will contend with you in judgment, because you have said: I have not sinned." So also Job wished to engage, who said in chapter 13: "I will speak to the Almighty, and I desire to dispute with God"; and Jeremiah 12: "Indeed you are just, O Lord, if I dispute with you; yet I will speak what is just to you." He also engages in war with the king of heavenly providence when he prepares himself for the struggle of patience, as it is said in Job 6: "Who will grant that my petition may come, and that God may give me what I await; and that he who has begun may himself crush me"? Thus in three ways war is waged with a king spoken of in three ways.
The first is waged by penance for sins, the second by confidence in merits, and the third by patience under scourges.
62. Second, as to the foresight of danger, he adds: Does he not first sit down and consider, in order to take forethought, according to that word of Deuteronomy 32: "O that they would be wise and understand, and would foresee their last end"! On account of which, Ephesians 5: "See how you walk carefully, not as unwise, but as wise, redeeming the time, because the days are evil. Therefore do not become imprudent" etc.
Whether he can with ten thousand meet — namely, to resist — him who comes against him with twenty thousand, to attack. And this admits of a threefold exposition, just as the preceding. For if it is expounded of the king of pride, we meet him through the works of the virtues, which consist in the mean, and which are therefore called ten thousand on account of the observance of the ten commandments; and the adversary comes with a doubled number, because to any virtue there corresponds a twofold vice from the opposite side, according to excess and defect. Whence, because there are more ways to go astray than to go straight, those in the army of the king opposed to us are said to be more numerous; whence Judith 1: "He gloried as one mighty in the power of his army and in the glory of his chariots." But one must neither flee nor fear, because, as is said in 1 Maccabees 3, "it is easy for many to be shut up in the hands of few; and there is no difference in the sight of the God of heaven to deliver by few or by many, for not in the multitude of an army is the victory of war, but from heaven is strength."
63. But if it is understood of the king of justice, we meet with ten thousand, that is, with confidence in merits from the observance of the ten commandments; and He with twenty thousand, that is, with the severity of judgments, in which there is an examination of works and thoughts. Whence Bede: "He meets with ten thousand who offers the works of the ten commandments, but God comes against him as if with a doubled number, when He examines one scarcely prepared in work alone concerning both work and thought together." From which it is given to understand that just as it is not safe with ten thousand to assail twenty thousand, so it is not safe to contend with that Judge. On account of which, Job 9: "Truly I know that a man is not justified when compared with God. But if he should wish to contend with Him, he could not answer Him one thing out of a thousand." Whence Malachi 3: "Behold, He comes, says the Lord of hosts; and who shall be able to think upon the day of His coming? For He is like a refining fire," etc.; and in the Psalm: "Thou art terrible, and who shall resist Thee?"
But if it is understood of the king of heavenly providence, he goes with ten thousand who wishes to endure great and many things for Christ, but He with twenty thousand, because He endured incomparably more for us, since He Himself is "the giant of twofold substance"; on account of which, in the Psalm: "What shall I render to the Lord for all the things that He has rendered to me?" And Micah 6: "What worthy thing shall I offer to the Lord?" etc.
64. (Vers. 31.). Third, as to the provision of a remedy, he adds: Otherwise, while the other is still far off, he sends an embassy and asks for terms of peace, namely, if he recognizes his own weakness with respect to this threefold battle, he labors to avoid that fight. The sending of this embassy is nothing other than the sending of prayer, which the Angels carry on our behalf before the sight of God as our ambassadors: Tobit 12: "When you prayed and gave alms and buried the dead, I offered your prayer before the Lord." This embassy must be sent for repelling the battle of temptations, which come from the king of pride: as Paul prayed, of whom 2 Corinthians 12: "There was given me a thorn in my flesh, an angel of Satan to buffet me: for which reason I three times besought the Lord," etc. — Likewise, this embassy must be sent for repelling the battle of divine contentions, which comes from the king of justice, as the Prophet prayed in the Psalm: "Enter not into judgment with your servant, O Lord, for in your sight no living person shall be justified," etc. The embassy must also be sent for repelling the battle of tribulations, which comes from the king of providence, as Jonah prayed in Jonah 2: "Jonah prayed to the Lord his God from the belly of the fish and said: I cried to the Lord from my tribulation, and he heard me."
From which it is gathered that the consideration of danger stirs one to the procurement of a remedy: whence the Gloss: "We, attending to the insufficiency of our frailty, ought to send ahead an embassy of tears, good works, and pure affections to obtain peace from the severe judge." Therefore it is said in Sirach 18: "Before sickness apply the medicine, and before judgment examine yourself, and in the sight of God you will find propitiation. Before sickness humble yourself, and in the time of infirmity show your manner of life," so that thus through the embassy of priests you may find the King appeased.
65. (Vers. 33.). So therefore every one of you, etc.
After he set forth the parabolic example of the one building and the example of the one waging war, here thirdly he sets down the application of both. And since these examples were introduced to stir us to providence regarding what is opportune and to caution regarding what is harmful and to give spiritual understanding of both: therefore in this part the application of the aforementioned examples is introduced with regard to providence regarding what is opportune, with regard to caution regarding what is harmful, and with regard to the spiritual understanding of both.
First, therefore, as to providence regarding what is opportune, he says: So therefore every one of you who does not renounce all that he possesses, through contempt of temporal things, cannot be my disciple, through the perfection of spiritual things: as if to say: just as the builder cannot finish without resources, nor the one waging war safely undertake battle without soldiers, so no one can perfectly follow Christ unless he renounces all things.
66. And note that the discipleship of Christ is twofold: one of necessity, as is said in the ninth and sixth chapters of Acts, that those who are now called Christians were accustomed to be called disciples, concerning which discipline, Isaiah 1: "Cease to do perversely, learn to do well." The other is the discipleship of supererogation, by which one follows Christ in the evangelical counsels, concerning which, Matthew 5: "Jesus, seeing the crowds, went up onto the mountain; and when he had sat down, his disciples came to him." For the first discipleship it is necessary to renounce all things, as regards the contempt of earthly things; but for the second it is necessary to leave all things behind, not only as regards affection, but also as regards the thing itself. Whence the Gloss: "This is the difference between renouncing all things and leaving all things behind, because to renounce befits all who so licitly use the worldly things they possess that they nevertheless tend in mind toward eternal things. To leave behind belongs only to the perfect, who set aside all temporal things and long for eternal things alone," and this is necessary for the perfect disciples of Christ, so that they may be conformed to the poverty of the Master. Whence, on that passage of Matthew 19: "Behold, we have left all things and followed you," Bernard says: "Well said, Peter, and not to your folly, because you could not follow one who runs while burdened. He rejoiced as a giant to run his course. " For since the first among the teachings of Christ is: "Blessed are the poor in spirit," whoever is ignorant of this consequently does not know "what are the elements of the beginning of the words" of Christ; and through this he is not a disciple of Christ nor does he understand him. And therefore Antiochus, who is interpreted as the silence of poverty, overthrew the foundations of Jerusalem, because he who despises the counsel of poverty cannot be a disciple of the poor Crucified One.
67. (Verse 34). Second, as regards caution against a harmful thing, he adds: Salt is good, but if the salt loses its savor. By salt is understood every perfect disciple, who ought to season the hearts of others by example and word; whence Matthew 5: "You are the salt of the earth"; which is said because he ought to have the highest discretion in conduct, according to that passage of Colossians 4: "Let your speech always be seasoned with salt in grace"; because, just as food cannot be eaten unless it is seasoned with salt, so neither does the stomach of the heart receive an indiscreet word: Job 6: "Can that which is unsavory be eaten, which is not seasoned with salt?" He ought also to have wisdom in contemplation: whence in Leviticus 2 it is commanded that salt be offered in every sacrifice. And such a one, who is prudent and wise, is rightly the seasoning of the Church by word and example: whence the Gloss: "Salt seasons food, kills worms, dries flesh; so preaching preserves human nature unharmed from the worms of vices and corruption for its Creator."
But then the salt loses its savor when a disciple of Christ becomes undevout in contemplation and indiscreet in action and in preaching, as is said of such ones in Romans 1: "They became vain in their thoughts, and their foolish heart was darkened," etc.; and this is the greatest danger.
Therefore he adds: With what shall it be seasoned? As if to say: with nothing; whence Sirach 12: "Who will have pity on a charmer struck by a serpent?" As if to say that such a one is utterly contemptible and useless, both before God and before men, both in spiritual acts and in temporal ones.
68. (Verse 35.). Therefore he adds: It is useful neither for the land nor for the dunghill, but it will be cast out. The Gloss: "Because he who goes backward is able neither to bear fruit himself nor to cultivate others"; indeed, what is more, he renders the land barren, because a perfect man who falls renders others useless for doing good by his bad example. And therefore the man who turns back is compared to the wife of Lot, of whom it is said in Genesis 19 that "looking back, she was turned into a pillar of salt"; and therefore Proverbs 6: "An apostate man, a worthless man, walks with a perverse mouth," etc. Just as therefore a building begun and not completed is useful for nothing, and a man who began and did not finish is derided by all; and similarly he who is overcome in battle: so also the apostate disciple is despised as salt that has lost its savor: whence Matthew 5: "It is good for nothing any longer, except to be cast out and trampled underfoot by men."
