It's a religious communal celebration. That's even the word that's used, for that matter. The celebration of the Mass.

There was a time not so long ago when the Catholioc Church used to impose a rule about not attending religious services of other religions, but thank God that's over and done with. If there are other religions still with those kind of rules, it's a sad thing, but that's how it goes, and I hope it won't last for ever.

I think it's the most naturaL thing in the world for religious services to form part of folk festivals. Whether they are interdenominational affairs, or a particular church (or meeting house, or synagogue or whatever) is playing host to whoever wants to come seems to me a matter for the people taking part to decide.

When I've been to the Fleadh Ceoil I've been to the Mass, and it's been worth going to for anyone, in my opinion. And I'd like it fine if they had religious celebrations in the other denominations as part of the Fleadh as well.
