In RCIA, you will learn that due to the error of people thinking that they didn’t get ‘complete Jesus’ unless they took both cup and host (blood and body), as though the Body wasn’t complete without the Blood, and the Blood without the Body, meaning that Jesus was ‘two separate pieces’ (yuck), many centuries ago the Catholic Church only gave the congregation the host (body) because ALL CHRIST was contained therein. It kept a lot of problems at bay (people were no longer swilling from the cup, dropping the precious blood, etc), or getting upset if they didn’t ‘get both’.
Then the US bishops, from a praiseworthy attempt, feeling that humanity had advanced enough NOT to get the wrong idea and were ‘ready’ to receive both signs with knowledge and reverence, allowed the reception IF the individual bishops or priests so CHOSE.
IOW, there are MANY parishes in the US where only the Host is offered. And it is perfectly fine. One gets JUST AS MUCH JESUS through the Host as through Host and Chalice.
Unfortunately, people are NOT as advanced as the bishops thought. Instead of people understanding the Real Presence and receiving reverently, people think of the Eucharist as a symbol and get upset if they only get “HALF OF JESUS” (as they improperly understand), or think they MUST have both because only one is not ‘complete’. They’re right back to where they were centuries ago.
The bottom line is that while it is a ‘fuller’ sign for those who are in a state of grace and proper understanding, it is not ‘required’ that any Catholic receive ‘both cup and host/blood and body’ as first, only ONE of the two contains it ‘all’, and second, no Catholic need receive the Eucharist AT ALL at Mass, especially if he/she is not in a state of grace.
Anyway, God’s blessing to you. It sounds to me as though you will very likely be one of those who understands the teaching and will happily partake of BOTH Body and Blood, and that is perfectly fine and wonderful; just as wonderful would be if you understood and took only one, but again, it is up to you. As I said, I think you DO understand and will be a good example to your fellow Catholics once you are received into the Church.
