That is hardly a comparison to the discussion.
God is spirit. Spirit has a wholly different existence than matter and we have very little idea as to the rules under which it operates.
But, in the Incarnation the Second Person of the Trinity became a man without ceasing also to be God.
In the same way the terrestrial elements communicate of the divine attributes in the Eucharist.
The analogy is as perfect as analogies get.
I don’t think it is proper to say of one miracle (the eucharist) that we know how it happens, but that of another (the Incarnation) we do not. Why is the one treatable and the other not?
This seems to be a dodge, and again there is the repeated reference in the fathers to the iconic connection between the meal and the Incarnation.
On the other hand, bread is matter. If the bread becomes flesh, it is not bread any longer because flesh and bread are both matter. The only thing which there is to be changed is the matter. Bread does not have a spirit of breadness about it which is changed into a spirit of fleshness.
I fail to see how this necessarily follows. Do you not say that the bread and wine become the body, blood,
soul and divinity?
If the bread becomes not only flesh but the soul and divinity of Christ, and if in the Incarnation, God, a Spirit, became a man without losing His divinity, I just don’t see how it follows that the bread would become the whole Christ and necessarily cease to be bread .
Since we confess the same Christology; i.e. that in Christ the divine and human are inseparable, I may have doubts about the necessity of the use of the expression (“body, blood, soul and divinity”, as though any of them could be separated from any of the others), I certainly admit the truth communicated.
There is a change from one to the other and the first ceases to be. This is how matter behaves.
But we are not talking about ordinary matter.
We are talking, when we refer to Christ, to God in a glorified body, capable of walking through walls, disguising himself so that his close friends could not recognize him, and able to be present everywhere the Eucharist is celebrated even at the same time in many different places.
