Let’s look at what Jesus thought of physically ingesting his flesh and blood.

Matthew 15:17 Do not ye yet understand, that whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught?

[Natural Law]

"Let’s look at what Jesus thought of physically ingesting his flesh and blood."

Except that Jesus was not referring to His body in Matthew 15:17, He was explaining a parable about Kosher requirements. To presume that this one out of context verse negates His many commands to eat His body and drink His blood and His references to the bread of life is just not plausible.

Further, you have to understand the philosophical difference between accident and substance to understand the Catholic teaching on this subject. If you would like some more information I would be more than happy to help you. If not I see no reason to arm wrestle you over this.
