I have read all the replies and my sense of things not being quite right was correct. So if you find yourself in that kind of a situation what should you do? If I could have gone to another church I would have. The next nearest church is 60 miles away. Would it really have been better not to go at all? Of course, I didn’t know what the service was going to be like till I was in the middle of it. So its back to, what should you do if you find yourself in the middle of a service like that and you know they are not doing things in the right manner?
No, I certainly wouldn’t have stayed home. This service is designed to provide for the situations when there is no other Mass available to faithful who either a) regularly gather for Mass or b) are gathered for a particular occasion, expecting Mass (as the Solemnity last night), and, for some reason, a priest is not available (sick, detained, etc.). It sounds like this celebration was actually done for the right reasons, in the correct circumstances.
Questions I would ask, though, would be:
Was there a Mass scheduled for this time, and the priest was simply unable to make it for some grave reason?
Was there a Mass earlier or later in the day, that the faithful could have reasonably attended? In which case, the need for the Communion Service is debatable.
Was this a planned Communion Service, “just to have something”, in which case, I would not have scheduled the service, and guided the faithful to one of the other churches in the area, or one of the other Masses at another time of day.
In any case, you celebrated as you were able, and in good conscience. As others have pointed out, you may want to bring your concerns up to your parish priest, and, if there is the possibility of this happening again, I would suggest a training for suitably competent volunteers. I do assume that you have no deacon available, who would be the Ordinary Minister of this celebration were it to be necessary again.
