What Do Catholics Do During the Triduum?

The Triduum is the heart of the Christian liturgical year. During these three days of Holy Week, we celebrate the greatest mystery of the Catholic faith: Redemption. The Passion, Death, and Resurrection of Jesus Christ are not commemorated as past events, but rather made present, becoming real for each generation of believers.

The Catechism of the Catholic Church teaches it clearly:

Therefore, Easter is not simply one feast among others: it is the “Feast of feasts,” “Solemnity of solemnities,” just as the Eucharist is the Sacrament of sacraments (the great sacrament). Saint Athanasius calls it “the great Sunday” ( Epistula festivalis 1 [year 329], 10: PG 26, 1366), just as Holy Week is called in the East “the great week.” The Mystery of the Resurrection, in which Christ has crushed death, penetrates our old time with its powerful energy, until everything is subjected to it.

At the Council of Nicaea (year 325), all Churches agreed that Christian Easter should be celebrated on the Sunday following the full moon (14th of the month of Nisan) after the spring equinox. Due to various methods used to calculate the 14th of the month of Nisan, the date of Easter does not always coincide in the Churches of the West and the East. For this reason, these Churches are currently seeking an agreement to once again celebrate the day of the Lord’s Resurrection on a common date.

Do you want to gain much spiritual fruit during these days? We present a complete guide to the Triduum: what Catholics celebrate on Holy Thursday, Good Friday, and Holy Saturday, and how we can live each day with fervor and piety.

What is the Triduum?

The Triduum is the three-day liturgical period that celebrates the Passion, Death, and Resurrection of Jesus Christ. It begins with the evening Mass of Holy Thursday, passes through the silence of Good Friday and Holy Saturday, and culminates with Vespers on Easter Sunday.

It is not a preparation for Easter: it is Easter itself. The Church does not divide these three days into independent celebrations, but lives them as a single great celebration extended in time. Therefore, the Triduum occupies the same place in the liturgical year as Sunday occupies in the week: it is the center of gravity around which everything else revolves.

When does the Triduum begin? It begins with the Mass of the Lord’s Supper, the evening Mass of Holy Thursday. Lent also ends at that moment.

When does the Triduum end? It ends with Vespers on Easter Sunday, although in pastoral practice its celebration culminates with the Mass of Easter Sunday.

How many days does the Triduum last? It consists of three liturgical days: Holy Thursday from evening, Good Friday, Holy Saturday, and Easter Sunday. In the liturgical reckoning, the day begins at sunset, according to the Jewish biblical tradition.

The Three Days of the Triduum and their Liturgy

Holy Thursday

Holy Thursday is the day when everything begins. The evening Mass In Cena Domini introduces the faithful to the core of the mystery through three inseparable gestures:

• The institution of the Eucharist. In the Upper Room, Jesus anticipates his sacrifice on the cross by offering his Body and Blood under the species of bread and wine. Each time the Church celebrates Mass, it makes that same mystery present. That is why Holy Thursday Mass is not just another Mass: it is the celebration of the origin of all Masses.
• The institution of the priesthood. By saying “do this in memory of me,” Jesus confers upon his apostles the command and power to renew his sacrifice. Holy Thursday is the birthday of the priesthood of the New Covenant.
• The washing of the feet. Jesus rises from the table, girds himself with a towel, and washes the feet of his disciples. A gesture reserved for slaves in the culture of the time. With it, Christ establishes humility and service as the characteristic mark of his reign.

At the conclusion of the liturgy, the Blessed Sacrament is transferred in solemn procession to the Altar of Repose — a place of eucharistic reservation prepared for adoration — while the Pange Lingua is sung. The bells fall silent. The altar is stripped. The Triduum has begun.

Good Friday

Good Friday is the only day of the year when the Eucharist is not celebrated on any altar in the world. The Church abstains from the sacrifice of the Mass and focuses all its attention on the wood of the Cross. It is a day of obligatory fasting and abstinence.

The liturgical action of Good Friday unfolds in three moments:

• Liturgy of the Word

The center is the account of the Passion according to Saint John, which presents Christ not only as a victim but as the High Priest who freely offers himself to the Father. The celebration begins in total silence: the priest and ministers prostrate themselves before the stripped altar in a gesture of profound adoration. This is followed by the Universal Prayer, the most solemn of the year, which raises petitions for the Church, the Pope, the faithful, rulers, and all humanity.

• The Adoration of the Cross

It is a rite of Hierosolymitan origin — the Church of Jerusalem already celebrated it in the 4th century — in which the faithful recognize the instrument of their salvation through a gesture of prostration or a kiss. The liturgical color is red, symbolizing both the kingship of Christ and his sacrifice. As the faithful approach, the Church sings the Reproaches: the moving dialogue between Christ and his people.

• Holy Communion

The faithful receive communion with hosts consecrated the previous day at the Holy Thursday Mass. It is the only time of the year when communion is distributed outside of Mass with hosts from a previous celebration.

At the end, the altar is stripped again. The Cross remains in a visible place so that the faithful can pause before it in prayer and meditation.

Holy Saturday

Holy Saturday is the least understood day of the Triduum and, perhaps for that reason, the most necessary. The Church remains by the Lord’s tomb in silence, fasting, and prayer. The Eucharist or any other sacrament is not celebrated in the ordinary way. There is no liturgical color. There is no music. Only waiting.

The Catechism of the Catholic Church teaches that during this day Christ “descended into hell”: not a place of condemnation, but the biblical sheol where the righteous who had died before the Redemption awaited (n. 632-635). Jesus descends there as Savior to proclaim the Gospel to them and open the gates of eternal life.

At the center of this silent day is the figure of the Virgin Mary under her title of Our Lady of Solitude. While the disciples are scattered by fear, Mary remains firm in faith and hope. The tradition of the Church recognizes her as the only one who kept the flame of faith burning during that long Saturday.

The silence of Holy Saturday is not an emptiness: it is a listening. The waiting of one who knows that the promise is true, even if it has not yet been fulfilled.

The Easter Vigil: the mother of all vigils

On the night from Saturday to Sunday, the Church celebrates the Easter Vigil, the most important celebration of the Christian year. It must take place during the night: it begins after nightfall and must end before dawn on Sunday. The entire celebration takes place in darkness that gradually gives way to light.

The Vigil unfolds in four moments:

• The Service of Light

The new fire is blessed and the Paschal Candle is lit, a symbol of Christ the Light who dispels the darkness of the world. The deacon — or the priest — proclaims the Exsultet, the great Easter Proclamation that sings the glory of the resurrection and traces the history of salvation from creation to Easter night.

• Liturgy of the Word

Up to seven readings from the Old Testament are proclaimed, narrating the wonders of God: creation, the sacrifice of Abraham, the crossing of the Red Sea, the promises of the prophets. It is the history of salvation that finds its fulfillment in the resurrection of Christ. After the last Old Testament reading, the Gloria resounds for the first time since Holy Thursday, and the bells — silent since that night — ring again.

• Liturgy of Baptism

The Easter Vigil is the night par excellence for receiving Baptism. Catechumens who have prepared their entry into the Church during Lent are baptized, confirmed, and receive the Eucharist for the first time. The entire assembly renews its baptismal promises and is sprinkled with blessed water, recalling their own baptism.

• Liturgy of the Eucharist

The culmination of the Vigil. The community participates for the first time in the banquet of the Resurrection. The Alleluia, absent throughout Lent, resounds again in the church with all its force. Christ has risen.

Norms of the Holy See for the Paschal Triduum

The celebration of the Paschal Triduum is regulated by the circular letter Paschalis Sollemnitatis of the Congregation for Divine Worship. Its most relevant indications for the faithful are:

• The authenticity of the signs

Liturgical signs must be authentic and noble: fire, candle, water, bread, and wine must be real. The Paschal candle, for example, must be made of natural wax, not artificial.

• The singing

It is essential to express the solemnity of these days. Paschalis Sollemnitatis gives priority to the singing of the assembly and ministers over any other musical element.

• The communal celebration

During the Triduum, private Masses without an assembly are not permitted. All celebrations must be communal, because the Triduum is by nature a celebration of the entire Church, not of small groups.

• The sobriety of the Altar of Repose

The place of eucharistic reservation on Holy Thursday must be sober and austere, inviting prayer without ostentation that distracts attention from the mystery of the Passion.
