Saint Cyril of Alexandria (Church Father)

“Christ said indicating (the bread and wine): ‘This is My Body,’ and ‘This is My Blood,’ in order that you might not judge what you see to be a mere figure. The offerings, by the hidden power of God Almighty, are changed into Christ’s Body and Blood, and by receiving these we come to share in the life-giving and sanctifying efficacy of Christ.” (Saint Cyril of Alexandria, Commentary on the Gospel of Matthew, [26, 27], (c. 428)
