Which part????
Jesus said that in order to have eternal life, you had to eat His body and blood. Catholics are the ones who demand that that passage be taken literally.
If that's the case, then the host MUST be literally be transformed into the literal flesh and blood of Jesus and literally be eaten.
Are you now telling us that that is NOT the case?
With each post of yours I read there is less and less evidence that you were ever Catholic. At best you were nominally Catholic. Catholicism has always referred to the Eucharist as the Host. This was especially true when you were allegedly Catholic. What do you think "host" means in plain, literal English? It is a shame that you apparently rejected the faith because you didn't acquire a proper understanding of it. There is more integrity in a person who says "I fully understand the issue and reject or disagree" than with a person who says "I haven't got a clue, I don't care to know, so don't bother me with the facts".
I'll ask you the question again; "Which part, the divine substance or the physical properties of the specific species?"
If you choose to be obtuse and to obfuscate to mask your inability or unwillingness to answer a tough but relevant question that is your prerogative. Just don't waste my time with mini-lectures and questions while doing so. Dialog is a bi-directional communication, not a hostile interrogation in which you get to ask all of the questions and answer none.
May you grow in Grace and Wisdom.
