Luke 17:31

Because good men must needs on account of the wicked be sore vexed in this world, in order that they may receive a more plentiful reward in the world to come, they are here punished with certain remedies, as it is here said, In that day, &c. that is, if a man goes up to the top of his house and rises to the summit of the highest virtues, let him not fall back to the groveling business of this world.

For he is on the housetop who, departing from carnal things, breathes as it were the free air of a spiritual life. But the vessels in the house are the carnal senses, which many using to discover truth which is only taken in by the intellect, have entirely missed it. Let the spiritual man then beware, lest in the day of tribulation he again take pleasure in the carnal life which is fed by the bodily senses, and descend to take away this world’s vessels. It follows, And he that is in the field, let him not return back; that is, He who labors in the Church, as Paul planting and Apollos watering, let him not look back upon the worldly prospects which he has renounced.

Matthew relates all these things to have been said by our Lord, with reference to the destruction of Jerusalem, that when the Romans came upon them, they who were on the housetop should not come down to take any thing, but fly at once, nor they that were in the field return home. And surely so it was at the taking of Jerusalem, and again will be at the coming of Antichrist, but much more at the completion of all things, when that intolerable destruction shall come.

He hereby implies that a persecution will come from the son of perdition upon Christ’s faithful. By that day then He means the time previous to the end of the world, in which let not him who is flying return, nor care to lose his goods, lest he imitate Lot’s wife, who when she deaf out of the city of Sodom, turning back, died, and became a pillar of salt.

Because thus she looked behind, she lost the gift of her nature. For Satan is behind, behind also Sodom. Wherefore flee from intemperance, turn away from lust, for recollect, that he who turned not back to his old pursuits escaped, because he reached the mount; whereas she looking back to what was left behind, could not even by the aid of her husband reach the mount, but remained fixed.

Lot’s wife represents those who in time of trouble look back and turn aside from the hope of the divine promise, and hence she was made a pillar of salt as a warning to men not to do likewise, and to season as it were their hearts, lest they become corrupt.

Next follows the promise, Whosoever shall seek, &c. as if he said, Let no man in the persecutions of Antichrist seek to secure his life, for he shall lose it, but whoso shall expose himself to trials and death shall be safe, never submitting himself to the tyrant from his love of life.

How a man may lose his own life to save it, St. Paul explains when he speaks of some who crucified their flesh with the affections and lusts, that is, with perseverance and devotion engaging in the conflict.

In Exodus the Jewish people, prefigured as a shadow and image of us, when, with God for their guardian and avenger, they had escaped the most severe slavery of Pharaoh and of Egypt, that is, of the devil and the world, faithless and ungrateful in respect of God, murmur against Moses, looking back to the discomforts of the desert and of their labour; and, not understanding the divine benefits of liberty and salvation, they seek to return to the slavery of Egypt, that is, of the world whence they had been drawn forth, when they ought rather to have trusted and believed on God, since He who delivers His people from the devil and the world, protects them also when delivered. “Wherefore hast thou thus done with us,” say they, “in casting us forth out of Egypt? It is better for us to serve the Egyptians than to die in this wilderness. …

54. This recapitulation is found in a still more obscure form; as, for example, our Lord says in the gospel: “The same day that Lot went out of Sodom it rained fire from heaven, and destroyed them all. Even thus shall it be in the day when the Son of man is revealed. In that day, he which shall be upon the house-top, and his stuff in the house, let him not come down to take it away; and he that is in the field, let him likewise not return back. Remember Lot’s wife.” Is it when our Lord shall have been revealed that men are to give heed to these sayings, and not to look behind them, that is, not to long after the past life which they have renounced? Is not the present rather the time to give heed to them, that when the Lord shall have been revealed every man may receive his reward according to the things he has given heed to or despised? And yet because Scripture says, “In that day,” the …
