The first thing I thought of when she told me this was, "Who receives Communion that way?"
Here's the answer:
Concelebrating priests receive the Eucharist from the main celebrant BEFORE he receives and they all Communicate together.
So what does it say when a priest does what my friend described? It treats the laity as concelebrating ministers of the Eucharist which is fundamentally dishonest and confusing. It also removes their right to receive on the tongue which is the preferred form of reception.
Pray for shepherds who scandalize the flock. The German Church is a mess as the divorced/Communion debate is illustrating.
Jesus said clearly that those who are faithful in small things will be faithful in greater. I'm not sure how small the liturgical abuse described is frankly. It sounds pretty serious to me. But, isn't it interesting that priests are often telling Catholics to conform to their own particular idiosyncrasies, like standing after Communion until everyone returns to the pew (real consideration for the elderly, eh?), while laity who refuse to conform to priestly browbeathing are anathemized and called lacking in humility. My take on it? Shepherd, heal thyself!
