Moveable feast
Ascension Day, observed on the Thursday forty days after Easter, commemorates the ascension of the risen Christ to the right hand of the Father (Luke 24:50–51; Acts 1:9–11). The feast closes the period of post-resurrection appearances and marks the beginning of the disciples' waiting for the promise of the Holy Spirit.
The Ascension is not Christ's departure from the world but his exaltation within it. As the BCP 2019 Collect puts it, he ascended that he might fill all things. The humanity he assumed at the Incarnation is not laid aside but carried into the life of the triune God — and with it, the hope of our own glorification.
Ascension Day is a Principal Feast and, in the BCP calendar, a Holy Day of Obligation wherever the parish observes such discipline. Its observance may be transferred to the following Sunday in some Anglican provinces and dioceses.
The Ascension is one of the oldest feasts on the Christian calendar, older than Christmas and nearly as old as Easter itself. Egeria, a pilgrim (likely a nun) traveling from the western edge of the Roman world, kept a diary of the liturgical year she found in Jerusalem in the early 380s. She records that by then the fortieth day after Easter was already marked at Bethlehem with an all-night vigil, and that the Mount of Olives, the traditional site of the Ascension, drew its own readings and hymns that same season, "suitable to the day and the place." Within a generation or two the Apostolic Constitutions could simply legislate what had become common practice: "Count forty days from the first Day of the Lord until the fifth day of the sixth week, and celebrate the feast of the Ascension of the Lord" (Apostolic Constitutions V.19). Gregory of Nyssa and John Chrysostom were already preaching sermons for the day before the fourth century closed. By then Ascension Day stood as its own feast, forty days out from Easter, always a Thursday.
What the Church has kept on this day has never been Christ's absence. Luke ends his Gospel not with the disciples grieving a departure but "worshiping him" and returning to Jerusalem "with great joy" (Luke 24:52); Acts opens the same scene from the other side, with two messengers in white turning the disciples' eyes from the sky back to the work in front of them (Acts 1:10-11). The Ascension is Christ's session, his taking of the throne, not his exit. Paul tells the Ephesians that God raised Christ and "seated him at his right hand in the heavenly places, far above all rule and authority and power and dominion," putting "all things under his feet" (Ephesians 1:20-22). Augustine, preaching on Christ's promise in John's Gospel to go and prepare a place for his own, has the Lord say plainly what the feast confesses: "And if I go, He says, and prepare a place for you, I will come again, and receive you unto myself," in John Gibb's translation of Augustine's homily on John 14:1-3 (Tractate 67). The ascended Christ has not left the world behind; he has gone ahead of it, into the place his own are promised.
The Ascension's narrative core sits in two texts by the same author. Luke's Gospel ends with Jesus leading the disciples out to Bethany, blessing them, and being "carried up into heaven" while they worship him (Luke 24:50-53). Acts opens by widening that same scene: it names the forty days of resurrection appearances (Acts 1:3), then describes the cloud that takes Jesus from the disciples' sight, the two men in white who redirect their gaze, and the return "to Jerusalem from the mount called Olivet, which is near Jerusalem, a Sabbath day's journey away" (Acts 1:6-11; Acts 1:12). Bethany sat on the eastern slope of the Mount of Olives; Luke's two accounts describe the same place at different scales, not two different places.
Paul supplies the doctrine the narrative implies. Ephesians describes God's power at work in Christ, "seating him at his right hand in the heavenly places, far above all rule and authority" (Ephesians 1:20-23), and reads the ascent against an earlier descent: the one who "descended into the lower regions, the earth" has "ascended far above all the heavens, that he might fill all things" (Ephesians 4:8-10). Hebrews gives the ascended Christ his ongoing office, a "great high priest who has passed through the heavens" (Hebrews 4:14-16) who has "entered... into heaven itself, now to appear in the presence of God on our behalf" (Hebrews 9:24).
Ascension Day is one of the seven Principal Feasts of the 2019 Book of Common Prayer, ranked with Christmas, Easter, and Pentecost, though it is easy to let a Thursday feast pass unmarked on a calendar built around Sundays. Where it is kept, it is kept as the other Principal Feasts are: proper collect and lessons, the Gloria restored, a note of triumph rather than ordinary time.
The feast does not ask a worshipper to imagine Christ as far off, gone to a place beyond use. It asks the opposite: that the same Christ enthroned in the day's readings is, at this hour, interceding for the one who prays them.
For three days before Ascension Day, Monday, Tuesday, and Wednesday, the Western church has long kept the Rogation Days: days of fasting and processional prayer asking God's blessing, especially on the year's planting and harvest. Bishop Mamertus of Vienne is credited with introducing them in Gaul around 470, after a series of disasters struck his city; the Council of Orléans made the observance binding across Gaul in 511, and Rome adopted it under Pope Leo III around the year 800. Their English form became "beating the bounds," a parish procession that walked (and blessed) the parish boundary while reciting litanies. The custom is largely gone from parish life now, but the Sunday before Ascension is still sometimes called Rogation Sunday, and readings and prayers asking God's blessing on labor and land can still be found set aside for it.
In the older Western use, the paschal candle, burning continuously since the Easter Vigil, was extinguished after the Ascension Day Gospel, a visible sign that the forty days of resurrection appearances had ended. Some modern Western calendars instead keep it burning through Pentecost, to underline the unity of the fifty days; both customs are attested. White remains the color of the feast, as for the Church's other commemorations of Christ's own person and work.
The day has its own hymnody. Charles Wesley's "Hail the day that sees him rise," written for Ascension and published with his brother John in Hymns and Sacred Poems (1739), is the best known English hymn for the feast; its "Alleluias" are a later addition, not Wesley's own, added by G. C. White in 1852. Older still is the Latin office hymn "Aeterne Rex altissime" ("O eternal King most high"), sung at Matins for Ascension in the Western breviary tradition since late antiquity. Its authorship is disputed; some scholars have traced its opening stanzas to Ambrose of Milan, but the attribution is conjectural, and the hymn as it survives shows signs of later hands.
Primary sources. Egeria's diary of her pilgrimage to the Holy Land in the early 380s is the earliest eyewitness account of how the fortieth day after Easter was kept in Jerusalem and Bethlehem, worth reading for its plain, on-the-ground detail (a bishop reading, hymns "suitable to the day and the place," an all-night vigil) rather than for theology. The 1919 Society for Promoting Christian Knowledge translation by M. L. McClure and C. L. Feltoe is freely available through the Christian Classics Ethereal Library. Augustine preached often on the Ascension and returns to it in his homilies on John's Gospel; his sermon on Christ's promise to "go and prepare a place," in John Gibb's translation, is available through New Advent's Fathers of the Church collection (Tractate 67 on John 14:1-3) and is a useful entry point for readers who want Augustine's own voice rather than a paraphrase of it.
Further reading. Thomas J. Talley's The Origins of the Liturgical Year (Pueblo Publishing, 1984; 2nd ed., Pueblo Books, 1991) remains the standard scholarly account of how the fortieth-day observance separated out from the older, single fifty-day Paschal season; a reader who wants the full case behind the dating claims above should start there. Douglas Farrow's Ascension and Ecclesia: On the Significance of the Doctrine of the Ascension for Ecclesiology and Christian Cosmology (Eerdmans / T&T Clark, 1999) is the standard modern theological treatment, arguing that the doctrine of the Ascension, not the Resurrection alone, is what gives the Church its shape and its waiting; dense, but the fullest case for "enthronement, not absence." Patrick Schreiner's The Ascension of Christ: Recovering a Neglected Doctrine (Lexham Press, 2020) covers similar ground for a reader who wants an afternoon's read rather than a monograph.
Online resources. The Episcopal Church's glossary entry on Rogation Days and the Catholic Encyclopedia's article on Rogation Days both give reliable, concise histories of the custom described above, useful for a reader who wants the Rogation-tide material without a full monograph.
The letter to the Hebrews gives that session its ongoing shape. Christ has "passed through the heavens" as "a great high priest" (Hebrews 4:14), not to retire from his people's cause but to plead it: he "always lives to make intercession" for those who come to God through him (Hebrews 7:25), having "entered... into heaven itself, now to appear in the presence of God on our behalf" (Hebrews 9:24). The Prayer Book's collect for the day asks that "our hearts and minds also there ascend, and with him continually dwell": not a wish that the Church might follow Christ out of the world, but a plea to live now under the reign of the one who already intercedes for it there.
The Ascension also explains why the Church waited ten more days before Pentecost. Christ tells his disciples, before his death, that his going is to their advantage: "it is to your advantage that I go away, for if I do not go away, the Helper will not come to you" (John 16:7). The Spirit's coming at Pentecost is not a consolation for Christ's absence; it is what his enthronement makes possible. Paul reads the sequence the same way in Ephesians, the one who "descended into the lower regions" now having "ascended far above all the heavens, that he might fill all things" (Ephesians 4:9-10). The ten days between the feasts mirror the interval Acts describes, when the disciples returned to Jerusalem and "with one accord devoted themselves to prayer" until the Spirit came.
