Pentecost

← Encyclopedia

Pentecost is the Christian feast kept on the fiftieth day after Easter, commemorating the descent of the Holy Spirit upon the first followers of Jesus. The name is Greek — pentēkostē, “fiftieth” — and it was first the Greek-speaking Jewish name for a festival already old when the church inherited it. The number is not loose. It is a measured interval: a span of days deliberately counted out, one by one, so that the feast arrives not on a fixed square of the calendar but at the end of a reckoning.

That older festival is the Feast of Weeks, Shavuot, one of the three pilgrimage feasts the Hebrew Bible commands. The instruction that fixes it stands in the festival calendar of Leviticus: from the day the wave-sheaf of the new barley is brought, seven full weeks — seven sabbaths — are to be completed, and on the morrow of the seventh sabbath, fifty days numbered, a new grain offering is presented (Leviticus 23:15-16). This is the only one of the appointed feasts in that calendar with no date of its own; it has a position rather than a date, arrived at by counting. The act of counting itself became a discipline — the counting of the omer, the sheaf — marking each of the forty-nine days between the barley harvest and the wheat. At the center of the day stand the loaves: two of fine flour, baked with leaven, lifted up as the firstfruits of the wheat (Leviticus 23:17). In its earliest layer the festival is therefore a harvest feast, the late-spring close of the grain ingathering, when the first bread of the new crop is given back before the rest is eaten.

A second meaning gathered around the day over time. Rabbinic tradition came to read Shavuot as the anniversary of the giving of the Law at Sinai. The linkage is not spelled out in the Torah itself; it is drawn from the chronology of the Exodus, where Israel reaches the wilderness of Sinai “in the third month” — the month of Sivan, the month in which the Feast of Weeks falls — and the sages inferred that the covenant was given on the same day the harvest feast was kept. The earliest attestations of this reading belong to the second and third centuries of the common era; the synagogue would come to name the day the season of the giving of the Torah. By the time the day acquired this name in fixed liturgical form, the harvest feast had become, in addition, a feast of revelation: bread brought up from the threshing floor and Law brought down from the mountain, kept on one date. It was to keep this pilgrimage that, in the Acts of the Apostles, Jews “from every nation under heaven” had gathered in Jerusalem — the period of Second Temple Judaism being one in which the three pilgrim feasts drew the diaspora back to the city.

The Acts 2 event

The Christian observance grows directly from that scene. Acts reports that as the followers were assembled together on the day of Pentecost, a sound came from heaven like a rushing mighty wind and filled the whole house where they were sitting; tongues “as of fire” appeared, divided, and rested on each of them; and they were filled with the Holy Spirit and began to speak in other tongues (Acts 2:1-4). The crowd of pilgrims — the text names Parthians, Medes, Elamites, dwellers in Mesopotamia, Cappadocia, Egypt, Rome, and more — each heard the apostles in his own native language. What follows is the first public preaching of the movement: Peter stands and explains the sign by quoting the prophet Joel, that in the last days God will pour out his Spirit upon all flesh, so that sons and daughters prophesy. The pouring-out is the hinge of the reading. The harvest feast is reread as a harvest of a different kind — the first ingathering of a new people, gathered not by language but across it.

Christians read this scene as the birth of the church and as the fulfillment of a promised Spirit. The promise is internal to the narrative: in the gospels and the opening of Acts the gift of the Spirit is foretold, the followers are told to wait in the city, and Pentecost is the day the waiting ends. The image is precise and worth holding still. A power descends from above — wind, fire, breath, the three old emblems of spirit in the Hebrew scriptures — and settles not on a temple or a throne but on a room of ordinary people, who are thereby commissioned to speak. The fire does not consume; it rests and divides, one flame to each. The many-tongued speech reverses, in the tradition’s own reading, the scattering of tongues at Babel: there language was confused to drive humanity apart; here the confusion is undone, not by erasing the languages but by making one message audible in all of them at once.

The typology of the fifty days

The parallel that holds the two feasts together is one the tradition itself draws, and it turns on the count. The Law was held to be given at Sinai fifty days after the first Passover; the Spirit is given fifty days after the death and rising of Christ. The structure is exact and deliberate. In the Christian reading, Passover finds its answer in the cross and the empty tomb, and the fiftieth day finds its answer in the upper room — deliverance followed, after the same interval, by the constitution of a people around a gift from on high. At Sinai the people receive a Law written on stone; at Pentecost a Law written, in the language of the apostle Paul, on the heart. The grain offered as firstfruits becomes the firstfruits of the new community. Each element of the older feast is taken up and turned: the harvest, the count, the firstfruits, the descent on the mountain, the voice that all the assembled hear. This is not a coincidence noticed after the fact but the architecture of how the church reads its own founding day — a typology in which the earlier event is the figure and the later one the thing figured, the two locked together by the number fifty.

Western forms: Whitsunday, fire, and the font

In Western Christianity the day acquired a second name, Whitsunday — “White Sunday,” after the white garments of the newly baptized, baptism at Pentecost being an old custom. Where catechumens had not been received at the Easter vigil, they were brought to the font on the eve of Pentecost and clothed afterward in a white alb; from that whiteness the English name descends, and the German Pfingsten preserves the older Greek “fiftieth.” The feast closes the long Easter season — the Great Fifty Days, which in the oldest layer of practice were themselves a single sustained festival of rejoicing rather than a count toward one final Sunday. The early witnesses describe this season more than the single day: Tertullian, at the opening of the third century, records that it was held unlawful to fast or to pray kneeling between Easter and Pentecost, the upright posture itself an expression of paschal joy.

In the liturgical churches the color of Pentecost is red, for the fire and the Spirit — the vestments and hangings of the day carrying the tongues of flame onto the altar and the ministers. The liturgy of the day reads the Acts narrative as its first lesson and, in the older Western rite, kept an octave, an eight-day extension of the feast. The pilgrim Egeria, writing of fourth-century Jerusalem, describes a Pentecost of enormous scale: the city’s whole population moving in procession from the place of the resurrection up the Mount of Olives and back to Sion, the Acts of the Apostles read at the very site where the descent was held to have happened, the single day stretched across the holy places of the city.

Eastern forms: the Trinity and the kneeling

Eastern Christianity keeps the day as one of its great feasts and folds into it a commemoration of the Trinity — the descent of the Spirit understood as the moment the Godhead is fully made known: Father, Son, and Spirit revealed together, so that the day is also called Trinity Sunday or the Day of the Holy Trinity. The Eastern Orthodox observance carries a distinctive sequence. The Sunday is the feast of the Trinity; the Monday following is kept as the Day of the Holy Spirit; the days are not a sequel but a continuation of the one descent. On the evening of the feast comes the service of the Kneeling Prayers — three long prayers ascribed to Basil of Cappadocia, the first kneeling permitted since Easter. The point is the posture itself: from Pascha to Pentecost the faithful stand, because the season is all resurrection, and the bending of the knee at Pentecost marks the return of ordinary supplicating time. This is the same discipline the First Council of Nicaea fixed in its twentieth canon in 325, directing that prayer be made standing on the Lord’s day and through the days of Pentecost — the season’s joy written into the body. In the Slavic churches the vestments and the church itself turn green, strewn with cut grass and decked in birch and other green boughs, the descending Spirit read as the greening of the world.

The recurring template

Among Pentecostal and charismatic movements of the last century the events of Acts 2 became a template for present experience rather than a founding event sealed in the past. The reading is direct: what was poured out on the apostles is poured out still, and the marks of it — the gifts of the Spirit, prophecy, healing, and above all speaking in tongues — are available to any believer who receives the Spirit’s baptism. The movement traces its modern beginning to a revival that opened in 1906 at a mission on Azusa Street in Los Angeles, gathered around the preaching of William Seymour on the fourth verse of Acts 2; from that mission the reading spread across continents within a generation, and the churches that hold it now number in the hundreds of millions. Where the older churches keep Pentecost as a fixed feast on the calendar, this current keeps it as an ever-repeatable threshold — the upper room understood as a door that opens again wherever the conditions are met, the fifty-day count collapsed into a present moment.

Texts and scholarship

The two scriptural floors of the feast are the festival calendar of Leviticus and the second chapter of Acts. The legislation of the Feast of Weeks — the count of seven weeks, the fifty days, the two leavened loaves of firstfruits — stands at Leviticus 23:15-22, part of the larger sacrificial and purity manual that the Tanakh and the Christian Old Testament hold in common; the standard critical treatment is Jacob Milgrom’s three-volume Anchor Bible Leviticus (1991-2001). The narrative floor is Acts 2 in the New Testament, read across the churches as the first lesson of the day. The development by which Shavuot acquired its second meaning — the season of the giving of the Torah — is traced, with the rabbinic sources, in accessible synthesis at My Jewish Learning, and at length in scholarship on the festival calendar of early Judaism.

For the Christian feast as kept rather than read, the early evidence is liturgical: Tertullian’s De Corona on the upright posture of the Great Fifty Days, the twentieth canon of the Council of Nicaea in Philip Schaff’s edition of the ecumenical councils, and the eyewitness Jerusalem liturgy of Egeria’s Itinerarium. The Orthodox reading of the day as the feast of the Trinity and the birthday of the church is set out by the liturgical theologian Alexander Schmemann in Pentecost: The Feast of the Church. The thread that runs from the harvest of loaves to the harvest of nations connects the feast to the wider Christian story told under Christianity and to the table of communion, where bread is again lifted and given; the larger scriptural frame within which both feasts sit is the one set out under Bible.

What runs through the festival in all its forms is a single image held across two religions and two harvests: a season of first-fruits, and a power descending from above to be poured out on those waiting below. The grain feast and the feast of fire keep the same place on the calendar, fifty days out, and the church has never stopped reading the one through the other.
