You both are confusing transformation with transubstantiation. In transformation, both substance and accidents are changed. In transubstantiation the substance changes, the accidents remain.
The accidents of bread such as taste, shape, weight, ect, remain. The substance, what it is called and known as, is transubstantiated.
Ask a philosophical and religious question, get a philosophical and religious answer.
Uh—I don’t think that there is any confusion with transformation with transubstantiation in my answer—if you re-read it, I have substituted the word “properties” for “accident” because outside of a certain philosophical universe it is more likely to be understood, and I haven’t bothered to list the accidents because they might further obscure a simple answer, but I don’t think that the substance of my post differs from yours.
Nope...Substance is not a title or name...Substance is the result of the properties involved which results in taste, feel, look, smell, etc...
Accidents are unintended consequences...Bread is the result of intended consequences and can be changed by the properties...
