"Triduum" derives from a Latin root word that means “three days.” It is a period of time that commemorates the final days of Jesus' life: his passion (suffering), death, and resurrection.
HOLY THURSDAY
Father, for your glory and our salvation you appointed Jesus Christ eternal High Priest. May the people he gained for you by his blood come to share in the power of his cross and resurrection by celebrating his memorial in this eucharist, for he lives and reigns with you and the Holy Spirit, God for ever and ever. (Liturgy of the Hours)
GOOD FRIDAY
Look, we pray, O Lord, on this your family,
for whom our Lord Jesus Christ
did not hesitate to be delivered into the hands
of the wickedand submit to the agony of the Cross.
Who lives and reigns with you
in the unity of the Holy Spirit,
one God, for ever and ever.
Amen. (Liturgy of the Hours)
Anima Christi
Soul of Christ, sanctify me.
Body of Christ, save me.
Blood of Christ, inebriate me.
Water from the side of Christ, wash me.
Passion of Christ, strengthen me.
O Good Jesus, hear me.
Within your wounds hide me.
Permit me not to be separated from you.
From the wicked foe, defend me.
At the hour of my death, call me
and bid me come to you,
That with your saints I may praise you
For ever and ever.
Amen.
HOLY SATURDAY
All-powerful and ever-living God,
your only Son went down among the dead
and rose again in glory.
In your goodness
raise up your faithful people,
buried with him in baptism,
to be one with him
in the eternal life of heaven,
where he lives and reigns with you and the Holy Spirit,
one God, for ever and ever.
Amen. (Liturgy of the Hours)
Prayer to Be Joined with Christ in Death
O Lord, Your sorrowing Mother stood by Your Cross;
help us in our sorrows to share Your sufferings.
Like the seed buried in the ground,
You have produced the harvest of eternal life for us;
make us always dead to sin and alive to God.
Shepard of all, in death you remained hidden from the world;
teach us to love our hidden spiritual life with You and the Father.
In Your role as the new Adam, You went down among the dead
to release all the just there since the beginning; grant that all
who are dead in sin may hear Your voice and rise to new life.
Son of the living God, You have allowed us through baptism
to be buried with You; grant that we may also rise with You
in baptism and walk in newness of life.
Amen.
EASTER VIGIL
Exultet
Receive it as a pleasing fragrance, and let it mingle with the lights of heaven.
May this flame be found still burning by
the Morning Star: the one Morning Star
who never sets, Christ your Son, who,
coming back from death's domain, has shed his peaceful light on humanity,
and lives and reigns for ever and ever.
Amen. (Easter Proclamation)
EASTER SUNDAY
O God, who on this day,
through your Only Begotten Son,
have conquered death
and unlocked for us the path to eternity,
grant, we pray, that we who keep
the solemnity of the Lord’s Resurrection
may, through the renewal brought by your Spirit,
rise up in the light of life.
Through our Lord Jesus Christ, your Son,
who lives and reigns with you in the unity of the Holy Spirit,
one God, for ever and ever.
Amen. (Liturgy of the Hours)
