I see you are quite busy with other posters, so I don’t know if you’ll see this, but I did want to respond briefly, just to let you know I wasn’t ignoring you.
As to the question you are asking, I have elaborated on it elsewhere and I am short on time and do not feel like unfurling the whole thing again. Bottom line, there are some who use the word “real” to mean “corporeal plus.” But real is whatever actually exists, and that can be spirit just as much as it can be atoms and quarks. God is spirit, and God is real. Therefore spirit is real.
Take that definitional framework back to the original context of the post of mine you’re quoting, and it should be quite clear to you what I am saying. Transubstantiation, no. Spiritual presence, yes, and as real as it gets.
Peace,
