"The presence of Christ's true body and blood in this sacrament cannot be detected by sense, nor understanding, but by faith alone, which rests upon Divine authority. Hence, on Lk. 22:19: 'This is My body which shall be delivered up for you,' Cyril says: 'Doubt not whether this be true; but take rather the Saviour's [...]
"Because the sufferings of My Only-Begotten are seen perpetually in the secret places of Heaven; and thus that oblation is united to My Son in My ardent heat in a profoundly miraculous way and becomes most truly His body and blood. And thence the Church is quickened with blessed strength." -St. Hildegard of Bingen relaying [...]
"Hilary says (De Trin. viii): 'There is no room for doubt regarding the truth of Christ's body and blood; for now by our Lord's own declaring and by our faith His flesh is truly food, and His blood is truly drink.' And Ambrose says (De Sacram. vi): 'As the Lord Jesus Christ is God's [...]
