Let’s get a little Patristic here…First while not a church Father how about the Good Doctor’s take… (Aquinas Pange Lingua)
Code:
1. PANGE, lingua, gloriosi
Corporis mysterium,
Sanguinisque pretiosi,
quem in mundi pretiumfructus
ventris generosi
Rex effudit Gentium.
2. Nobis datus, nobis natus
ex intacta Virgine,
et in mundo conversatus,
sparso verbi semine,
sui moras incolatus
miro clausit ordine.
3. In supremae nocte cenae
recumbens cum fratribus
observata lege plene
cibis in legalibus,
cibum turbae duodenae
se dat suis manibus.
4. Verbum caro, panem verum
verbo carnem efficit:
fitque sanguis Christi merum,
et si sensus deficit,
ad firmandum cor sincerum
sola fides sufficit.
5. Tantum ergo Sacramentum
veneremur cernui:
et antiquum documentum
novo cedat ritui:
praestet fides supplementum
sensuum defectui.
6. Genitori, Genitoque
laus et iubilatio,
salus, honor, virtus quoque
sit et benedictio:
procedenti ab utroque
compar sit laudatio.
Amen. Alleluia.
And an English rhyming translation:
Code:
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
Amen. Alleluia.
Cyril of Jerusalem

On the night he was betrayed our Lord Jesus Christ took bread, and when he had given thanks, he broke it and gave it to his disciples and said: “Take, eat: this is my body”. He took the cup, gave thanks and said: “Take, drink: this is my blood”. Since Christ himself has declared the bread to be his body, who can have any further doubt? Since he himself has said quite categorically, This is my blood, who would dare to question it and say that it is not his blood?
Therefore, it is with complete assurance that we receive the bread and wine as the body and blood of Christ. His body is given to us under the symbol of bread, and his blood is given to us under the symbol of wine, in order to make us by receiving them one body and blood with him. Having his body and blood in our members, we become bearers of Christ and sharers, as Saint Peter says, in the divine nature.
Do not, then, regard the eucharistic elements as ordinary bread and wine: they are in fact the body and blood of the Lord, as he himself has declared. Whatever your senses may tell you, be strong in faith.
Code:
You have been taught and you are firmly convinced that what looks and tastes like bread and wine is not bread and wine but the body and the blood of Christ. You know also how David referred to this long ago when he sang: Bread gives strength to man’s heart and makes his face shine with the oil of gladness. Strengthen your heart, then, by receiving this bread as spiritual bread, and bring joy to the face of your soul.
