I’m not sure if this is the right place to ask this, but here goes. Every Sunday at Mass, I see the priest say the words of institution over a piece of bread and a chalice of wine - turning these hosts into the body and blood of Christ. Then, I see a wholely seperate container of bread and wholely seperate chalices brought out of the tabernacle to be handed out to the faithful. Are these hosts previously blessed with the words of institution? If so, when? Is there a whole seperate Mass? Are they “left-overs”? Or do the words said over the priest’s hosts count for these others? I’ve had this question for a while, but always just assumed it was a really dumb question. But, I also don’t want to have it come up in a conversation with one of my protestant friends and have me have to say “I don’t know.”
Thank you for your help.
