The Easter Triduum begins with the evening Mass of the Lord’s Supper on Holy Thursday, reaches its high point in the Easter Vigil, and closes with Evening Prayer on Easter Sunday.
Many parishes offer Eucharistic Adoration after the Holy Thursday Mass. After the Mass, the altars are stripped, the holy water fonts are emptied, and the Blessed Sacrament is carried through the church in procession to a place of reposition. All the beautiful symbols of Christ's Presence in the tabernacle are removed to give us the sense of His entering most fully into His Passion.
Here are some prayers and hymns for Eucharistic Adoration. These are also availble in PDF form in English and Spanish.
O salutaris hostia, Quae caeli pandis ostium: Bella premunt hostilia, Da robur fer auxílium.
Unitrinoque Domino Sit sempiterna gloria: Qui vitam sine termino Nobis donet in patria.
O Saving Victim, op’ning wide The gate of heav’n to us below! Our foes press on from ev’ry side: Your aid supply, your strength bestow.
To your great name be endless praise, Immortal God-head, one in Three; O grant us endless length of days When our true native land we see.
Tantum Ergo (Come Adore)
Tantum ergo Sacramentum Veneremur cernui: Et antiquum documentum Novo cedat ritui: Praestet fides supplementum Sensuum defectui.
Genitori, Genitoque Laus et jubilatio, Salus, honor, virtus quoque Sit et benedictio: Procedenti ab utroque Compar sit laudatio.
Down in adoration falling Lo! The sacred Host we hail; Lo! O’er ancient forms departing, Newer rites of grace prevail; Faith for all defects supplying Where the feeble senses fail.
To the ever lasting Father, And the Son who reigns on high, With the Spirit Blest proceeding Forth from each eternally, Be salvation, honor, blessing, Might and endless majesty.
