What is the Body of Christ in the host made of?
Clearly the taste and colour of the host are accidents - they remain after consecration. After consecration, the substance is changed - the host is no longer bread, it is the Body of Christ.
The Church teaches that the host is not the Body of Christ AND bread. So it is not the Body of Christ made of bread.
Is it still made of atoms? Is it still made of carbon and hydrogen and nitrogen atoms? Or are those atoms now a different substance, with the accidents of atoms?
If it is made of atoms, then is it still made of the proteins and carbohydrates that those atoms form? Or are those structures no longer carbohydrates and proteins, but rather the Body of Christ with the accidents of carbohydrates and proteins?
The DNA and cells that remain - are they still DNA and cells, or are they the Body of Christ with only the accidents of DNA and cells?
