Since Christ Himself said in reference to the bread: "This is My Body," who will dare remain hesitant? And since with equal clarity He asserted: "This is My Blood," who will dare entertain any doubt and say that this is not His Blood?... You have been taught these truths. Imbued with the certainty of faith, you know that what seems to be bread is not bread but the Body of Christ, although it seems to be bread when tasted. You also know that what seems to be wine is not wine but the Blood of Christ although it does taste like wine.
Cyril of JerusalemIn regard to the divine and holy mysteries of the faith, not the least part may be handed on without the Holy Scriptures. Do not be led astray by winning words and clever arguments. Even to me, who tell you these things, do not give ready belief, unless you receive from the Holy Scriptures the proof of the things which I announce. The salvation in which we believe is not proved from clever reasoning, but from the Holy Scriptures.
Cyril of JerusalemO God of our fathers, and Lord of mercy, who has made all things with your word, and ordained man through your wisdom, that he should have dominion over the creatures which you have made, give me wisdom that sits by your throne so that I might understand what is your will and be saved. For I am your servant. Amen.
