Luke 14:28

For which of you, intending to build a tower, &c. By means of this parable Christ would teach us with what prudence we ought to test our bodily, and above all our spiritual strength, as well as such gifts of grace as we may possess, before we attempt to build the lofty tower of evangelical perfection, and declare war against ourselves our passions, our friends and the whole world; lest afterward, recoiling from so great an undertaking, we incur the loss of all our outlay, and also the reproach of having rashly commenced a building which we were unable to finish, and of having entered upon a war in which we were worsted.

"He counts the cost," says the Gloss, "who perceives that money will have to be spent, i.e. that the heart must be weaned from corrupt desires, and the soul prepared for adversity."

Symbolically. Salmeron (tom. vii. tract 24) says, "Christ puts forth two parables to teach the rulers of the Church that they must be skilled both in action and in contemplation, the one about building a tower, which is a symbol of contemplative life, for a tower commands an extensive prospect; the other, about engaging in war against a hostile king, which is significative of the active life.

"For those who are novices in the way of God, and are learning, as it were, the first elements of the perfect life, are called upon to battle with their enemies, and to fight against their vices and evil passions.

"By the tower therefore we may understand the religious state, which is coupled to the contemplative life.

"1. Because as a tower overtops all other buildings, so does a life of religion excel all other vocations and callings.

"2. As a tower gives grace to a city, so is the religious life an ornament to the Church.

"3. As a tower is a look-out, to discover the movements of the enemy, so in the contemplative life we look forth on the wiles of our adversary, and on the good and evil laid up in futurity.

"4. As a tower is a protection to them that dwell therein, so is a life of religion a defence against the world, the flesh and the devil, and a safe storehouse for the fruits of good works. So it is written, Song of Solomon 4:4, 'Thy neck is like the tower of David,... whereon hang a thousand bucklers,' i.e. the bucklers of holy vows, holy examples, and holy observances.

"5. As every one ought to count the cost before he commences to build a tower, so a year is given a novice in order that he may make trial of his fitness for the religious life. For he whose heart is fixed on heaven looks down as from a lofty tower upon the world which lies beneath, and counts it worthless."

So S. Chrysostom (hom. 15 ad. Pop.), says: "Just as to those who look back from the highest mountain tops, not only men and trees but even entire cities look small, and great armies seem to be creeping about like ants, so to those whose minds are uplifted by the constant contemplation of heavenly things, all human affairs, power, glory, riches, and the like, seem minute and worthless: unworthy of the greatness of the immortal soul."

Hear also the lament of S. Gregory, when he was called from a religious order to be the Pope: "Seeking nothing, in this world, and fearing, nothing, I seemed to stand on a certain eminence, so that I thought that the promise of God, 'I will cause thee to ride upon the high places of the earth' (Isa 58:14), had well-nigh been fulfilled in me. For he rides upon the high places of the earth, who despises and treads under feet all that this world counts great and glorious. But suddenly cast down from this eminence, and plunged into the whirl of temptation, I have became a prey to terror and affright, for although I fear nothing for myself, I fear much for those committed to my charge" (Lib. 1, epist. 5 and 6).
