There are many statements in Nicholas of Cusa’s sermons that emphasize the importance of faith in those who receive the body and blood of Christ in Holy Communion. This is likely due to his early education among the Brethren of the Common Life, but it also relates to his peculiar brand of Platonism.

Therefore, this faith is best signified by means of the visible form of bodily food, which expels weakness and furnishes strength—as do, basically, the wheaten bread and the wine. Hence, take cognizance of the fact that in the power of the bread and the wine—[a power] that expels the weakness of the flesh’s ravenous hunger and that brings strength, or renews strength, (things which happen with respect to the outer man)—faith sees the power of the Word working similar things in the inner man. And that which nature ministers to the outer man by means of visible food, faith by means of invisible Food (which is the Word of God) obtains in the inner man (which is invisible),  (Sermon CLXXXIII).
