Maybe it’s not too late to get your money back.
I’ve been a Catholic for 35 years this August, and I’ve received the Eucharist under both forms in every parish I’ve ever attended. That includes several foreign countries where I traveled.
More important from a theological perspective is this fact: when someone receives only the host, they are receiving the body, and the blood, and the soul and the divinity of Jesus. IOW, both species contain both His body and His blood. Scripture is clear on this:
1 Co 11:23-29
For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, “This is my body, which is for you; do this in remembrance of me.” In the same way, after supper he took the cup, saying, “This cup is the new covenant of my blood; do this, whenever you drink of it, in remembrance of me.” For whenever you eat this bread and drink this cup, you proclaim the Lord’s death until he comes. Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. A man ought to examine himself before he eats of the bread and drinks of the cup. For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.”
Paul says that anyone who eats OR drinks in an unworthy manner sins against both the body AND the blood. IOW, if you eat the bread unworthily, you sin against the body and blood
OR
if you drink the cup unworthily, you sin against the body and the blood.
Therefore, there is no problem for parishioners who do not receive the cup.
Now you know.
