[Dr. Eckleburg]

If I understand you correctly, you are not complaining about not being able to partake of the Eucharist in the RCC service; you are questioning the truth of its actual stated essence and purpose.

Which as you've shown us, is carefully explained by Christ...

"And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, [it] cannot defile him; Because it entereth not into his heart, but into the belly, and goeth out into the draught, purging all meats?

Here Christ is saying anything exterior to Himself is a non-essential, and is ultimately ineffectual and therefore purged.

What is important is He who gives the new heart and what comes from this new heart.

Precisely so, dear sister in Christ!

The exclusion has no effect whatsoever on the body of Christ of Whom we are all members.

For ye are dead, and your life is hid with Christ in God. – Colossians 3:3

The exclusion only reflects on the doctrine.

To God be the glory!
