From a reader:
I have a question about self-communication. I was at a monastery this weekend for a retreat and a monks allowed the laity to receive the Chalice. How they did it was a bit odd though. A lay brother took the chalice and set it on a table and stood by it. The communicants would go up. The brother would say "Blood of Christ" and the communicant would take the Chalice themselves and receive the Precious Blood and put the Chalice back down. The brother never held the Chalice during distribution. I didn’t receive this way because I wasn’t sure if it was permitted (and since I received the Host I didn’t think it was necessary). Is this considered self communication or am I being too scrupulous?
That is self-communication and it is not permitted.
44. The chalice may never be left on the altar or another place to be picked up by the communicant for self-communication (except in the case of concelebrating bishops or priests), nor may the chalice be passed from one communicant to another. There shall always be a minister of the chalice.
This describes what is necessary in the USA. I am reasonably sure that the norms are pretty much the same everywhere.
