O memoriale mortis Domini

The hymn below is used for Vespers for Holy Thursday, which is not said by those who participate in the evening Mass of the Last Supper. The hymn is an extract of St. Thomas Aquinas' (1225-1274) Adoro Te devote, which he composed in honor of the Blessed Sacrament.

O MEMORIALE mortis Domini! panis vivus, vitam praestans homini! praesta meae menti de te vivereet te illi semper dulce sapere.

O MEMORIAL of my Savior dying, Living Bread, that gives life to man; make my soul, its life from Thee supplying, taste Thy sweetness, as on earth it can.

Pie pellicane, Iesu Domine, me immundum munda tuo sanguine; cuius una stilla salvum faceretotum mundum quit ab omni scelere.

Deign, O Jesus, Pelican of heaven,me, a sinner, in Thy Blood to lave, to a single drop of which is given all the world from all its sin to save.

Te cum revelata cernam facie,visu tandem laetus tuae gloriae; Patri, tibi laudes et Spiritui, dicam beatorum iunctus coetui. Amen.
