This is a new one to me, so I thought I’d toss it out there and see if anyone has an answer.

A deacon reader writes:

Can you find out for me, the validity of a mass intention in the absence of a priest by a deacon doing a communion service?

I gather, from the sketchy details, that a mass that was to be celebrated for a particular intention had to be changed to a communion service, conducted by a deacon. Can the mass intention be switched? Is it valid?

Any thoughts?
