It’s Not Wrong for a Priest to Receive from a Layperson

According to a 1988 ruling by the Pontifical Council for Legislative Texts, even if a priest who is present is not concelebrating, he is to distribute Communion rather than a lay person.

If for whatever reason this does not take place, then it makes the most sense that the priest receive Communion like the rest of the congregation. It would be quite confusing if the priest simply walked up to the altar or took the host from the extraordinary minister’s ciborium.
