The accidents are often referred to in catechisms etc as the “appearances”. Are appearances the same thing as “physical properties”? I would have thought not.
I think the main issue here is one of what do words mean. What is a substance and what are accidents. These come from metaphysics and the writings of Aristotle and were adopted by St. Thomas, who used them with the same basic meanings as those before him unless I am greatly mistaken. Everything has substance, which is what a thing is in itself, and then accidents depend on that. Wood
is wood substantially, and the accidents are everything not the substance, and they depend on the substance and arise from it. Burn the wood and change the substance to ash, and the accidents then arise from that and you will see, touch and feel ash. These accidents are not mystical or illusory, but rather real properties which depend on the substance.
The word appearance is clearly just a reflection that in this case the accidents do not actually depend on the substance. In every other case they do. Wood cannot have the accidents of iron, to use your example. Iron has the accidents of iron, and so on. Change the substance and the accidents change, since they depend on the substance. But, in the Eucharist, the accidents are not based on the substance of Christ’s body, but miraculously are still those of bread. But, and this is crucial, the accidents are only appearances in that they do not show us the substance, i.e. what the thing really is. They show us bread.
I believe that if you were to take the host down to a lab and had it analyzed it would be bread. It would have wheat and water, and the density, texture, everything would be bread. Under a microscope it would have the glutens and contents of bread. This isn’t a trick of the eyes either. The atoms for bread are there. They simply no longer belong to bread, but now are the Body of Christ.
Is it not the case that Our Lord said nothing because he meant what he said? The problem with the crowds was their lack of faith which even Christ could not cure.
Well, you are confusing a few things. It is true that Christ would not change his teaching, but when his disciples grumbled in their hearts the Lord chided them. He said “It is the spirit that quickeneth: the flesh profiteth nothing. The words that I have spoken to you, are spirit and life.” This was his response to their their thought that this saying was hard, and we should see it in that light. He is correcting them, regardless of their willingness to hear. His words are Spirit and life, but they are flesh and hear in the flesh, which profits nothing. It is their carnal understanding, what might be called the natural understanding, that he is rebuking. Their lack of faith then allowed them to fall away over this. Notice that the other disciples do not object that they in fact do understand what the Lord is saying, but only to say that they have nowhere else to go as he has the words of eternal life. Faith holds them firm, in spite of their ignorance and carnal understanding. Both factors are at work here.
3)The TRUE position ( mine of course! ) :Our Lord is present in His physical resurrection body but ( as Pope Paul says , " not in the manner in which bodies are in a place. " ie. in an impassible way…taking up no space, unable to be broken or hurt etc.
Consider that even here you seem to be caught in a contradiction. You say “taking up no space” but that is exactly what physical means. If something is a physical presence, it takes up space. If you say it doesn’t take up space, then the presence is in some other manner than physical. I am not saying I agree with what you are saying here, but only indicating that you may be thinking more in line of a non-physical change than you are willing to consciously consider.
Is not " a shell of appearance " just what I have been saying…why then call it physical
Because it is physical. The accidents of the bread are unchanged, and so physically it is identical to bread. But, it is an appearance because it does not reveal its substance, which is not bread. The appearance, which is physical, is not what is really there, which is Christ.
My point was not that you held this precise view ( which you don’t) but that ( in my opinion) your view tends towards it.
I don’t think that is a problem though. Tending is not really reflective of truth. For instance, some could and have said that Trinitarian dogma
tends towards polytheism, but that doesn’t change the truth. Many truths can be turned or twisted to falsehoods. The Protestants didn’t start with nothing, but took what the Church gave them and then they debased it. Many can come very close to true dogma in this regard, and then just miss it in some very important way. The distinction of substance and reality is very, very important, and changes everything in this matter.
Am I being obtuse or dishonest in seeing in this last point a sort of non sequitur? I interpret “manner in which bodies are in a place” not simply as “physical”…that would be begging the question; I see this as referring to the impassible nature of Our Lord’s presence, which is an important statement as it dismisses any superstitious act or belief.
No, I don’t think you are being obtuse or dishonest, though I am likely inadequate to such refined aspects of theology. I will make just a couple of points here. One, I don’t think impassibility is at play here. Impassible would be a reference to God’s unchangeability in reference to emotion. He does not experience pleasure or pain and so on. So, I cannot be quite certain what you may be meaning to say about the kind of presence Christ’s Body has in the Eucharist with this word.
I also don’t intend any non sequitur. When I look at the quote you posted I see a very subtle point being made. Christ’s body is physical, but it is present not in the manner in which bodies are in a place. One comment speaks to the reality of the body, the other to the manner of the presence. The body we receive is real, and is the same physical body which rose from the dead, but it is made present for us not in a physical change of accidents, but rather a substantial presence. It is a corporeal presence but not manifested through a necessarily physical change of the elements. I am glad to admit that I may be misunderstanding the words, but this is really how I have seen them to be intended.
