As a Celiac, I have been battling with this teaching myself for a few years now.
I have such a hard time accepting that, until the recent low-gluten hosts from the Benedictine nuns in Missouri, there was no safe way for a Celiac to receive communion. How can I accept the teaching on transubstantiation? Yes, the accidents remain, but how can the Eucharist feed the soul if it kills the body? I cannot receive from the cup either as there is a small piece of host in it too. There are a few parishes that will pour a bit of wine in a seperate cup, but most parishes will not do this, and had I not this special host now (which, throughout history, no one had) I would not be able to receive at all.
Another thought that plagues me: “my words are spirit and truth”. Bearing this in mind, and knowing that the “accidents” still remain, and that the “flesh profit nothing”, I believe the Eucharist is spiritual food. Why would we need to literally eat of something in order to have eternal life?
In John 6:35 Jesus said: 35And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
I think this verse is very key to understanding the rest of John 6 and the Eucharist. And the last: 63It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
One thing I can tell you in all honesty, that in all the time I have been unable to receive communion, and now since I had decided to leave the Catholic church while I ponder these things, I have been fed marvelously upon His Word. His words truly are spirit and life, and you don’t have to search the world over to find them (like I had to in order to find a special host), nor do you have to live in an era of technological advances in order to have access to them (as Celiacs have had to do in order to receive safely). I don’t have to wait for a mass to attend in order to receive my nourishment. Use a concordance and do a study on the Word and see how much God has tried to impress upon us the importance of His Word.
I think those who left Jesus when He said these things didn’t have “ears to hear”. It wasn’t a parable he needed to explain. Jesus plainly says that his words are spirit and life - all after telling us that his flesh and blood give life.
I’m not trying to convince anyone of any of this. These are just my thoughts, of which I admittedly see problems with. I happened to have thought a lot about this when I awoke this morning and wanted to add some of my own 2cents to the discussion.
