St. Thomas Aquinas, the brilliant Dominican, was the author of the Summa Theologica and also the Office for the Feast of Corpus Christi, among other things. His works are still most prominent in value to the Roman Catholic faith.
ADORO TE DEVOTE of SAINT THOMAS AQUINAS
LOST, ALL LOST IN WONDER.
Godhead here in hiding, whom I do adore,
Masked by these bare shadows, shape and nothing more,
See, Lord, at thy service low lies here a heart
Lost, all lost in wonder at the God thou art.
Seeing, touching, tasting are in thee deceived:
How says trusty hearing? that shall be believed;
What God's Son has told me, take for truth I do;
Truth himself speaks truly or there's nothing true.
On the cross thy godhead made no sign to men,
Here thy very manhood steals from human ken:
Both are my confession, both are my belief,
And I pray the prayer of the dying thief.
I am not like Thomas, wounds I cannot see,
But can plainly call thee Lord and God as he;
Let me to a deeper faith daily nearer move,
Daily make me harder hope and dearer love.
O thou our reminder of Christ crucified,
Living Bread, the life of us for whom he died,
Lend this life to me then: feed and feast my mind,
There be thou the sweetness man was meant to find.
Bring the tender tale true of the Pelican;
Bathe me, Jesu Lord, in what thy bosom ran—
Blood whereof a single drop has power to win
All the world forgiveness of its world of sin.
Jesu, whom I look at shrouded here below,
I beseech thee send me what I thirst for so,
Some day to gaze on thee face to face in light
And be blest for ever with thy glory's sight.
(translation of Gerard Manley Hopkins, S.J.)
EUCHARISTIC HYMN OF ST THOMAS AQUINAS
PANGE lingua gloriosi
quem in mundi pretium
fructus ventris generosi
Rex effudit Gentium.
SING, my tongue, the Savior's glory,
of His flesh the mystery sing;
of the Blood, all price exceeding,
shed by our immortal King,
destined, for the world's redemption,
from a noble womb to spring.
Nobis datus, nobis natus
ex inacta Virgine,
et in mundo conversatus,
sparso verbi semine,
sui moras incolatus
miro clausit ordine.
Of a pure and spotless Virgin
born for us on earth below,
He, as Man, with man conversing,
stayed, the seeds of truth to sow;
then He closed in solemn order
wondrously His life of woe.
In suprema nocte coenae
recumbus cum fratribus
observata lege plene
cibis in legalibus,
cibum turbae duodenae
se dat suis manibus.
On the night of that Last Supper,
seated with His chosen band,
He the Pascal victim eating,
first fulfills the Law's command;
then as Food to His Apostles
gives Himself with His own hand.
Verbum caro, panem verum
verbo carnem efficit:
fitque sanguis Christi merum,
et si sensus deficit,
ad firmandum cor sincerum
sola fides sufficit.
Word-made-Flesh, the bread of nature
by His word to Flesh He turns;
wine into His Blood He changes;
what though sense no change discerns?
Only be the heart in earnest,
faith her lesson quickly learns.
Tantum ergo Sacramentum
et antiquum documentum
novo cedat ritui:
praestet fides supplementum
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 sense fail.
Genitori, Genitoque laus et jubilatio,
salus, honor, virtus quoque
sit et benedictio:
procedenti ab utroque
compar sit laudatio.
To the everlasting Father,
and the Son who reigns on high,
with the Holy Ghost proceeding
forth from Each eternally,
be salvation, honor, blessing,
might and endless majesty.
Grant me, O Lord my God, a mind to know you, a heart to seek you, wisdom to find you, conduct pleasing to you, faithful perseverance in waiting for you, and a hope of finally embracing you. – SaintThomas Aquinas
