Haydock's Catholic Bible Commentary: Matthew
Ver. 23. Lo, here is Christ. These words are very aptly applied by Catholics to the conventicles of heretics; and would Christians attend to the injunctions of their divine Master, Go ye not out:---believe it not, we should not see the miserable confusion occasioned in the Catholic Church, by unsteady Christians; who are guilty of schism, in forsaking the one true fold, and one shepherd, to follow their blind and unauthorized leaders. (Estius)
Ver. 26. Behold he is in the desert. This prediction of false Christs, may be understood before the destruction of Jerusalem, but chiefly before the end of the world. (Witham) --- As we have mentioned above, in note on verse 5.
Ver. 28. Wheresoever the body,[3] &c. This seems to have been a proverb or common saying among the Jews. Several of the ancient interpreters, by this body, understand Christ himself, who died for us; and they tell us, that at his second coming the angels and saints, like eagles, with incredible swiftness, will join him at the place of judgment. (Witham) --- When he shall come to judgment, all, as it were by a natural instinct, shall fly to meet him, and receive their judgment. St. Hilary understands this literally; that where his body shall hang upon the cross, there will he appear in judgment, i.e. near the valley of Josaphat; in which place the prophet Joel (chap. iii. ver. 2,) declares, that the general judgment shall take place. (Tirinus)
Ver. 29. The sun shall be darkened, &c. These seem to be the dreadful signs that shall forerun the day of judgment. --- The stars shall fall, not literally, but shall give no light. (Witham) --- According to St. Augustine, by the sun is meant Jesus Christ; by the moon, the Church, which will appear as involved in darkness.
Ver. 30. The sign of the Son of man, &c. The Fathers generally expound this of the cross of Christ, that shall be seen in the air. (Witham) --- This sign is the cross, much more resplendent than the sun itself. Therefore the sun hides its diminished head, whilst the cross appears in glory; because the great standard of the cross, excels in brightness all the refulgent rays that dart from the meridian sun. (St. Chrysostom, hom. lxxvii.) --- The Jews, looking upon him whom they had pierced, now coming in the clouds of heaven with power and exceedingly great glory, shall have great lamentations. Bitterly will they weep over their misery, in having despised and insulted him on a cross, who ought to have been the object of their veneration, adoration, and love. (St. Chrysostom, hom. lxxvii.)
Ver. 34. This generation; i.e. the nation of the Jews shall not cease to exist, until all these things shall be accomplished: thus we see the nation of the Jews still continue, and will certainly continue to the end of the world. (Tirinus) --- Then the cross, which has been a scandal to the Jew, and a stumbling-block to the Gentile, shall appear in the heavens, for the consolation of the good Christian. Hoc signum crucis erit in cœlo, cum Dominus ad judicandum venerit. --- If it be to be understood of the destruction of Jerusalem, the sense may be, this race of men now living; if of the last day of judgment, this generation of the faithful, saith Theophylactus,[4] shall be continued: i.e. the Church of Christ, to the end of the world. (Witham) --- This race, I tell you in very truth, shall not pass away till all this be finally accomplished in the ruin of Jerusalem, the most express figure of the destruction and end of the world. (Bible de Vence) --- By generation, our Saviour does not mean the people that were in existence at that time, but the faithful of his Church; thus says the psalmist: this is the generation of them that seek the Lord. (Psalm xxiii, ver. 6.) (St. Chrysostom, hom. lxxvii.)
Ver. 35. Shall pass away: because they shall be changed at the end of the world into a new heaven and new earth. (Challoner)
Ver. 36. No man knoweth ... but the Father alone. The words in St. Mark (xiii. 32.) are still harder: neither the angels, nor the Son, but the Father. The Arians objected this place, to shew that Christ being ignorant of the day of judgment, could not be truly God. By the same words, no one knoweth, but the Father alone, (as they expound them) the Holy Ghost must be excluded from being the true God. In answer to this difficulty, when it is said, but the Father alone, it is certain that the eternal Son and the Holy Ghost could never be ignorant of the day of judgment: because, as they are one and the same God, so they must have one and the same nature, the same substance, wisdom, knowledge, and all absolute perfections. 2. It is also certain that Jesus Christ knew the day of judgment, and all things to come, by a knowledge which he could not but have, because of the union by which his human nature was united to the divine person and nature. See Colossians ii. 3. And so to attribute any ignorance to Christ, was the error of those heretics called Agnoitai. 3. But though Christ, as a man, knew the day of judgment, yet this knowledge was not due to him as he was man, or because he was man, but he only knew the day of judgment, because he was God as well as man. 4. It is the common answer of the fathers, that Christ here speaks to his disciples, only as he was the ambassador of his Father; and so he is only to know what he is to make known to men. He is said not to know, says St. Augustine[5], what he will not make others know, or what he will not reveal to them. (Witham) --- By this Jesus Christ wished to suppress the curiosity of his disciples. In the same manner after his resurrection, he answered the same question: 'Tis not for you to know the times and the moments, which the Father has placed in his own power. This last clause is added, that the apostles might not be discouraged and think their divine Master esteemed them unworthy of knowing these things. Some Greek manuscripts add nor even the Son, as in Mark xiii. 32. The Son is ignorant of it, not according to his divinity, nor even according to his humanity hypostatically united to his divinity, but according to his humanity, considered as separate from his divinity. (Bible de Vence)
Ver. 37-38. And as it was. The same shall take place at the coming of the Son of man at the last day, as at the general deluge. For, as then they indulged their appetites, unmindful of the fate that was attending them, gamountes kai ekgamizontes, marrying and given in marriage, solely occupied with the concerns of this life, and indifferent to those of the next; so shall it be at the end of the world. They are not here accused of gross sins, but of a supine security of their salvation, as is evident from what follows. (Jansenius)
Ver. 39. And they thought not of the deluge, though preached and predicted by Noe, (which rendered their ignorance and incredulity inexcusable) till it came and swept them all away. So shall it be at the coming of the Son of man. St. Luke adds, (chap. xvii, ver. 28,) likewise as it was in the days of Lot; they shall be eating and drinking, buying and selling, planting and building, i.e. totally immersed in worldly pursuits. Hence the apostle; when they shall say peace, viz. from past evils, and security, viz. from future, then shall destruction come upon them on a sudden. But some one may ask, how can there possibly be all this peace, all this security, when the evils mentioned above, famines, wars, plagues, earthquakes, and particularly the darkness of the sun, &c. &c. are presages calculated to strike with panic and consternation minds the most thoughtless and giddy? I answer, that the wicked are chiefly designed here, who in the midst of the afflictions and alarms of the good, will still indulge in their pleasures and luxuries, like cruel soldiers, whilst the peaceable inhabitants are plundered. St. Jerome adds, that the world for some time before its final dissolution, will be freed from all those calamities. As to what is said (ver. 29,) of the darkness of the sun and moon, these are circumstances that refer to the very coming of the judge. (Jansenius)
Ver. 40. Then of two men, who shall think of nothing less than of going to appear before God, one shall be taken to be placed among the number of the elect, and the other shall be left condemned to eternal fire with the damned, on account of his crimes. (Bible de Vence) --- This example of the men in the field, and of the condition and disposition of men at the period of the deluge, strongly expresses how unexpectedly these evils will rush in upon mankind; and the subsequent account of the two women grinding in the mill, shews how little they were solicitous for their salvation. We are, moreover, taught by these examples, that some of all states and conditions will be saved, whether rich or poor, in ease or labour, or decorated with all the various degrees of worldly honour. The same is mentioned in Exodus, chap. xi, ver. 5. From the first-born of Pharao, who sitteth on his throne, even to the first-born of the handmaid that is at the mill, ... every first-born shall die. (St. Chrysostom, hom. lxxviii.)
