“The divine presence leaves whent he host is dissolved inside the body”
Ah...now this is very interesting! A definitive statement that can be examined.
I assume that you are referring to the wafer which is said to become the actual flesh of Christ upon being blessed. So what shall be said of the wine? At what point does “the divine presence” leave the wine?
And if this be so then is the participant ingesting bread and wine or flesh and blood? Does “the divine presence” leave at different points of ingestion for different persons? Say in the mouth, the stomach, the intestinal tract? Or is it a matter of time? After so minutes say?
But most importantly, How would anyone know this leaving of “the divine presence” had or had not occurred? Is there some teaching in the Catholic Catechism or of Catholic theologians? If so where?
I am most interested in learning how all this occurs!
Christ in present fully in either consecrated species, so long as either species remains in appearance, respectively, apparent bread or apparent wine. Body, blood, soul, and divinity of Christ is present either in the bread or in the wine. This is why a communion in bread alone or in wine alone is possible, and in fact for many centuries was the norm.
So it follows that so long as one of the two species remains what it appears to be, the entire Christ is present.
This is not something a Christian brain should be preoccupied with, especially at communion, but if you think it is important to know, here it is.
