Even worse, I have been encountering a growing number of Catholics who lack the Church’s understanding of concomitance.
They think of the species of wine as being the Blood to the exclusion of the Body, and of species of bread as being ‘Body’ to the exclusion of Blood.
As often as I can, I go to a noon Mass near work. It is not my home parish.
Chatting with one lady, an EMHC, she asked why I never received the Blood. I answered that I did, at just about every Mass. She replied that she often held the chalice and never saw me receive from it. I replied that was immaterial, as I received the Blood present in the Host.
It took the involvement of the priest to get her to understand that, yes I received the complete Body, Blood, Soul and Divinity of Christ with the reception of a single species.
And even then, I think the acceptance was grudging.
