The Early Church Fathers, Sunday, October 21, 2012, St Cyril of Alexandria

"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."
