- In the exposition of the faith by the Eastern Patriarchs, it is said that the word transubstantiation is not to be taken to define the manner in which the bread and wine are changed into the Body and Blood of the Lord;
for this none can understand but God; but only thus much is signified
, that the bread truly, really, and substantially becomes the very true Body of the Lord, and the wine the very Blood of the Lord.
In like manner John Damascene, treating of the Holy and Immaculate Mysteries of the Lord, writes thus: It is truly that Body, united with Godhead, which had its origin from the Holy Virgin; not as though that Body which ascended came down from heaven, but because the bread and wine themselves are changed into the Body and Blood of God. But if thou seekest after the manner how this is, let it suffice thee to be told that it is by the Holy Ghost; in like manner as, by the same Holy Ghost, the Lord formed flesh to himself, and in himself, from the Mother of God; nor know I aught more than this, that the Word of God is true, powerful, and almighty, but its manner of operation unsearchable. (J. Damasc. Theol. lib. iv. cap. 13, § 7.)
