The Unknown Hour: The Days of Noah and the Sudden Separation
36but my Father only.37As the days of Noah were, so will the coming of the Son of Man be.38For as in those days which were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered into the ship,39and they didn’t know until the flood came and took them all away, so will the coming of the Son of Man be.40Then two men will be in the field: one will be taken and one will be left.41Two women will be grinding at the mill: one will be taken and one will be left.
The end comes like a flood to those absorbed in ordinary life—the real danger is not sin but complacency, and you will not be warned because the hour is hidden.
Jesus declares that no creature — not even the angels — knows the day or hour of His return, only the Father. He uses the generation of Noah as a warning: ordinary life continued right up to the moment of catastrophe, and people were utterly unprepared. The sudden, discriminating "taking" and "leaving" of individuals in the field and at the mill underscores that the Parousia will be both universal and intensely personal — catching each person exactly as they are.
Verse 36 (partial — "but my Father only"): This verse concludes Jesus' declaration that "no one knows the day or the hour" — not the angels, not even the Son in His human knowledge. Catholic tradition, drawing on St. Augustine and St. Thomas Aquinas, interprets this as a statement about Christ's human intellect: as the Incarnate Word, He possesses the beatific vision, yet He "knows" within His mission only what He is sent to reveal (cf. Aquinas, Summa Theologiae III, q. 10, a. 2). The ignorance is not ontological but communicative — He does not reveal it because it is not given to creation to know. This is a deliberate withholding of information for our spiritual benefit: perpetual readiness requires perpetual uncertainty. The exclusive knowledge of the Father also stresses the absolute sovereignty of God over eschatological time.
Verse 37 — "As the days of Noah were": Jesus reaches back to Genesis 6–9 for His interpretive key to the Parousia. The comparison is typological: just as the flood was a universal, sudden judgment that divided the righteous from the wicked, so will the coming of the Son of Man be. The "days of Noah" are not characterized by extraordinary wickedness alone, but by normalcy — the scandal of ordinary life continuing without reference to God's approaching intervention. This is spiritually penetrating: the danger is not drama but complacency.
Verse 38 — "Eating and drinking, marrying and giving in marriage": The activities listed — eating, drinking, marrying — are not intrinsically sinful. Jesus is not condemning marriage or sustenance. The indictment is that these goods became the entire horizon of existence. St. John Chrysostom, in Homilies on Matthew (Homily 77), notes that the people of Noah's generation were not fornicating or murdering in this verse — they were simply absorbed in created goods to the exclusion of God. "Until the day that Noah entered the ship" — Noah's boarding is the final visible sign, and still they did not repent. The ship itself is a classic patristic type of the Church (Tertullian, De Baptismo 12; St. Cyprian, De Unitate Ecclesiae): outside the ark, no salvation. The precision of "until that day" emphasizes how late the world waited — and that it waited at all.
Verse 39 — "They didn't know until the flood came": The Greek ouk egnōsan — "they did not know" — is not intellectual ignorance but willful inattentiveness. Noah had preached righteousness to them (2 Peter 2:5). The knowledge was available; it was refused. The flood "took them all away" () — the same verb used in verse 40–41 for being "taken," though with opposite valence. Here it is sweeping destruction; there it will be separation. This verbal echo is deliberate: the question of whether to be "taken" is a question of which kind of taking one is prepared for.
Catholic tradition brings several unique lenses to bear on this passage. First, the typology of Noah and the Church: the Fathers unanimously read Noah's ark as a figure of the Church. Just as the ark bore the righteous through judgment while the world perished, the Church carries the faithful through history toward the Parousia. Lumen Gentium (§9) describes the Church as the new People of God, gathered and preserved amid a world that does not recognize its own peril — precisely the situation of Noah's contemporaries. To be in the Church is, typologically, to be in the ark.
Second, the hiddenness of the hour is a profound theological gift. The Catechism (CCC 673–677) teaches that the Church lives in an eschatological tension: Christ has already won the victory, yet the consummation is deferred. This deferral is mercy (cf. 2 Pet 3:9 — "He is patient with you, not wishing that any should perish"). The unknown hour is not a defect in revelation but a pastoral provision: it prevents both presumption (calculating the date and delaying conversion) and despair.
Third, the sudden separation speaks directly to Catholic moral theology's emphasis on the particular judgment (CCC 1021–1022): at the moment of death, each soul is judged by Christ. The Parousia brings the universal or Last Judgment, which makes public and cosmic what the particular judgment already established. The "one taken, one left" imagery teaches that eternity is determined by the orientation of a whole life — not a single dramatic moment — lived day by day at the mill and in the field. St. Thérèse of Lisieux captured this in her "little way": holiness is the sanctification of the ordinary, precisely the sphere Jesus invokes here.
For a contemporary Catholic, this passage cuts through the noise of modern eschatological sensationalism — date-setters, end-times calculation, apocalyptic media — with sovereign simplicity: you will not know the hour, so live as if it is this hour. The men in the field and the women at the mill are not in a church or at prayer when the Lord comes; they are at work. This sanctifies ordinary professional life as the arena of preparedness. The practical application is concrete: the Sacraments of the Church — especially regular Confession and the Eucharist — are the equivalent of entering Noah's ark. They are not emergency measures for spiritual crisis; they are the ordinary rhythm of a life kept ready. Catholic families might reflect on whether their daily lives — eating, drinking, working, marrying — are ordered toward God or have become, like Noah's contemporaries, an unconscious substitute for Him. The Office of the Dead and the Church's liturgical prayers for the faithful departed remind Catholics that the "sudden separation" is not only eschatological but occurs in every death around us — a constant, gentle summons to readiness.
Verses 40–41 — "One will be taken and one will be left": Two men in the same field, two women at the same millstone — the most ordinary agricultural scenes of first-century Palestine. The Parousia does not respect proximity, kinship, or shared labor. Catholic exegesis (see St. Jerome, Commentary on Matthew) has traditionally understood "taken" (paralēmpsetai) as taken up in glory, though some Fathers allow the reading that the "taken" are taken in judgment. The dominant Catholic reading, reflected in the Catechism (CCC 1038–1041), favors a reference to the gathering of the elect. Crucially, the separation is instantaneous and final — there is no purgatorial sorting at this moment of return; it is the Last Judgment's culmination, where all is already determined by a life lived.
