We see that grace can accomplish more than nature, yet so far we have been considering instances of what grace can do through a prophet’s blessing. If the blessing of a human being had power even to change nature, what do we say of God’s action in the consecration itself, in which the very words of the Lord and Savior are effective? If the words of Elijah had power even to bring down fire from heaven, will not the words of Christ have power to change the natures of the elements? You have read that in the creation of the whole world he spoke and they came to be; he commanded and they were created. If Christ could by speaking create out of nothing what did not yet exist, can we say that his words are unable to change existing things into something they previously were not? It is no lesser feat to create new natures for things than to change their existing natures.
